EXECUTIVE SUMMARY
Background
The Power System Analysis included Short Circuit, Protective Device Coordination, and Arc Flash
Hazard studies of electrical equipment at Eastern Municipal Water District Temecula Valley RWRF.
This study includes new equipment to be installed as part of a facility photovoltaic installation.
The Short Circuit study investigated the ability of equipment to interrupt and withstand a short circuit
occurrence. The Protective Device Coordination study determined the selective operation of protective
devices to assure the device closest to a fault or overload operates in order to minimize the number of
apparatus that are affected. The Arc Flash Hazard assessment calculated the amount of energy that
would be released in the event of an arcing short circuit at each equipment location. Personal
Protective Equipment (PPE) was then specified based on the available arc energy and other factors
such as the operating voltage of the equipment. PPE must be utilized by personnel performing work on
electrical equipment, unless the equipment has been de-energized and confirmed to be safe by lock-out
and tag-out testing procedures.
Data Gathering
Data for the analysis were collected from construction drawings, manufacturer’s submittals and shop
drawings. The data gathered included electrical plan and single-line drawings, equipment details, and
protective device ratings. Available fault current at the utility services was provided by Southern
California Edison.
Short Circuit Study
A short circuit study was performed in order to determine the maximum available short circuit current
at each equipment component included in this study. The calculated values of short circuit current were
compared to the equipment short circuit ratings. Equipment must have a withstand or interrupting
rating that exceeds the calculated value of short circuit current in order to safely withstand the
occurrence of a short circuit. If a device is subjected to short circuit currents greater in magnitude than
its ratings, equipment damage and injury to personnel are likely.
The short circuit study showed that all system components studied were suitably rated for the available
short circuit current. All devices in the system had a withstand or interrupting rating that exceeded the
worst-case calculated short circuit current, in compliance with California Electrical Code 110.9.

Protective Device Coordination Study
The goal of the Protective Device Coordination study is to provide proper coordination and time
separation between the operation of protective devices. Proper coordination among protective devices
will minimize the amount of equipment that would be affected by a short circuit or overload event. In
the event of a short circuit or overload, the protective device closest to the short circuit should operate
when devices are properly coordinated. In the event that the closest device does not clear the short
circuit the next upstream device should then operate.
Recommended protective device settings for adjustable devices are provided in Section 3 of this report.
The recommended protective device settings will provide coordination between upstream and
downstream circuit breakers, as well as minimize Arc Flash incident energy values.
Arc Flash Hazard Study
The Arc Flash Hazard study determines the incident energy and flash hazard boundary resulting from
an arcing short circuit. Warning labels for the equipment were produced as part of this study that
identify Arc Flash hazards, including approach boundaries, shock hazard boundaries, and required PPE
to be worn by personnel working on the equipment while it is energized.
The following equipment had calculated incident energies above 8.0 cal/cm2. Incident energies above
8.0 cal/cm2 require personnel to wear arc flash hazard suits with an arc rating that matches or exceeds
the incident energy calculated and printed on the arc flash warning label. Reduction of the incident
energy values at the following equipment is not readily feasible due to either relatively low available
fault current, or lack of adjustable settings on protective devices such as thermal-magnetic circuit
breakers and fuses. However, additional barriers and guards can be installed on equipment to provide
enhanced protection against accidental contact with energized equipment parts. Refer to Section 4.4 for
more details.

Validity Statement
This Power System Study and Arc Flash Hazard assessment is accurate as of the date of this report for
the equipment installed as shown on the attached one-line drawings. Changes to the electrical system
circuits, including system impedance, short-circuit duty, voltage, or fault clearing times, will invalidate
this study and require re-evaluation, calculation, and installation of new warning labels. This study
should be updated on a regular basis and at intervals no greater than allowed by applicable Codes and
standards.

Study Notes and Assumptions
•
•
•
SKM did not have a library file in the program for the XHHW conductors specified for this
project. Copper conductors with THHN/THWN insulation were used for circuits 600V and
below unless otherwise noted. The variance concerns the type of insulation used over the
conductor; not the conductor itself, and will not significantly affect the results of the studies
presented in this report.
The 1600A model LCL fuses used in the 1600A disconnect are shown in the study reports
as “Federal Pacific”. Federal Pacific’s fuse line was acquired by Edison Fuse Products,
which was later acquired by Cooper/Eaton. Eaton is providing the electrical equipment for
this project, including the LCL fuses. The time-current characteristics have not changed for
this particular model of fuse.
All overcurrent protective devices will perform as designed by the manufacturer, and
operate according to the manufacturer’s published time-current curves.

SHORT CIRCUIT STUDY
2.1
General
The purpose of the Short Circuit Study is to determine the levels of bolted fault current that can
flow in an electrical system when a fault occurs at a specific location in that system. Arc flash
calculations use this level of bolted fault current for determining arcing fault current and
incident energy levels. Circuit breakers and fuses must have an interrupting rating which
exceeds the maximum bolted fault current available at its location. Equipment such as
switchboards and panelboards must have a withstand rating of equal or greater value than the
calculated bolted fault current.
The Short Circuit Study models the electrical system impedance by determining an equivalent
impedance for all system components and then calculates bolted fault current at various busses.
The short-circuit duty is a function of the utility short circuit capacity, on-site source
contributions such as motors and generators, and system impedance from cables and
transformers. Bus locations may be identified by referring to the one-line diagram in Appendix
G of this report.
Two short circuit study cases were calculated: The first case uses the short circuit current
calculated by Solar City and the design engineer of record, the second case uses the short
circuit current calculated by Southern California Edison (SCE) in 2013. The value of current
calculated by Solar City was 64,174A at 480V. The values calculated by SCE were 25,500A 3phase, 27,300A single phase to ground, at 480V. As long as the main service switchboard or
service equipment is not upgraded, the short circuit values calculated by SCE should still be
valid.
The much larger value of short circuit current provided by Solar City is most likely based on an
infinite bus value of the largest utility transformer sized for the full 3,000A rating of the
existing 480V switchboard. Short circuit values using the infinite bus method yield
conservatively high values of current, and will be the “worst case” values calculated. The
values provided by SCE are based on the rating of the utility service transformer presently
installed, which is frequently rated less than the full-load rating of the customer switchboard.
Refer to Appendix D for values calculated by SCE. Utilities typically install a smaller-rated
transformer due to the fact that most customers have a peak electrical demand much less than
the full-load rating of the customer’s main service. Even though the short circuit value provided
by Solar City may be higher than what can be provided with presently installed service
equipment, the value is useful for specifying interrupting ratings of equipment. If the utility
service is upgraded in the future, the equipment installed for the photovoltaic system will still
have an adequate interrupting rating, and will not require component replacement as long as the
EMWD switchboard is not upgraded.
PES ran four study cases which considered the short circuit duties calculated by SCE and Solar
city, as well as short circuit current contribution from the photovoltaic arrays:

1. Short circuit values calculated by Solar City, no photovoltaic contribution.
2. Short circuit values calculated by SCE, no photovoltaic contribution.
3. Short circuit values calculated by Solar City, photovoltaic contribution per the inverter
datasheet. Per the inverter datasheet, the maximum short circuit contribution from the
inverter is 69.6A three-phase, 52.9A single line to ground. The inverter will only
conduct short circuit current for one cycle. After a maximum of 20ms, the inverter will
stop conducting current. Refer to Appendix F for the short circuit contribution from the
inverter.
4. Short circuit values calculated by Solar City, photovoltaic contribution per the inverter
datasheet. Per the inverter datasheet, the maximum short circuit contribution from the
inverter is 69.6A three-phase, 52.9A single line to ground. The inverter will only
conduct short circuit current for one cycle. After a maximum of 20ms, the inverter will
stop conducting current. Refer to Appendix F for the short circuit contribution from the
inverter.
2.2
Short Circuit Model Simplifications
A number of conventional simplifying assumptions were used to establish a system model that
reasonably represents the magnitude of fault current the system is capable of producing. The
assumptions generally produce a conservative or worst case set of values. The major
assumptions utilized in this study include the following:
•
•
•
•
•
•
2.3
Fault current calculations include initial symmetrical fault with ½ cycle asymmetrical
contribution.
Available fault current values at the utility services were obtained from Southern
California Edison and Solar City construction drawings, and are assumed to be valid for
the system model and conditions of this study.
Protective device impedances and equipment bus impedances were neglected.
Pre-fault voltages were set at 1.0 per unit.
Impedance elements remain constant during a system fault.
Reported fault levels represent three-phase and single-line-to-ground bolted faults.
Short Circuit Study Results
The results of the short circuit study identified that all components included in this study were
suitably rated for the available fault current under both study cases. Using both the short circuit
values calculated by Solar City, and the values calculated by SCE, each device had a withstand
or interrupting rating that met or exceeded the calculated available fault current, in accordance
with California Electrical Code 110.9.
For complete results of the Short Circuit study, including source and impedance ratings input
into the model and calculation results, refer to Appendix A of this report. Bus locations may be
identified by referring to the one-line diagram in Appendix G of this report.

PROTECTIVE DEVICE COORDINATION STUDY
3.1
General
The primary function of electrical power system fault protective devices is to detect a fault
current and to isolate the fault by activating the proper interrupting device. A fault should be
removed as quickly as possible by the closest upstream protective device to minimize fault
damage, maintain maximum service continuity, and protect property and personnel.
3.2
Calibration and Testing of Protective Devices
Current transformer ratios and sensor devices must be verified before making any changes to
protective device settings. After verification, protective devices can be set to provide the
characteristic curves shown in the appropriate TCC. In general, the specified settings will
provide operation of the devices as shown. However, equipment tolerances and possible
defects in device operation may result in deviations from the desired operating times. Therefore
the device settings should be calibrated by field tests to help assure the desired response.
Coordination depends on operation of the protective devices as shown, though the devices may
be normally inactive for long periods. To assure continuing device coordination, it is essential
that all protective devices are maintained, tested, and calibrated at regular intervals, as
recommended by the manufacturer.
3.3
Recommended Protective Device Settings
Recommended settings are provided below for all adjustable circuit breakers. Non-adjustable
circuit breakers and fuses are not listed below. The recommended settings will minimize arc
flash incident energy by minimizing breaker trip time, while maintaining device coordination
between main and feeder protective devices. These recommended protective device settings
should be programmed during equipment testing and commissioning.

ARC FLASH HAZARD STUDY
4.1
General
The arc flash hazard study determines the incident energy and flash hazard boundary resulting
from an arcing fault. Required PPE is then selected based on incident energy levels. Warning
labels are then produced that identify arc flash hazards, approach boundaries, and PPE ratings
to be worn by personnel working on the equipment while it is energized.
Work on energized parts exceeding 50 volts to ground may only be done in accordance with
Article 130.2 of the 2015 NFPA 70E.
“Energized electrical conductors and circuit parts shall be put into an electrically safe work
condition before an employee performs work if any of the following conditions exist:
(1) The employee is within the limited approach boundary.
(2) The employee interacts with equipment where conductors or circuit parts are not exposed
but an increased likelihood of injury from an exposure to an arc flash hazard exists.”
The Arc Flash module of SKM Power Tools was used for calculation of incident energy. The
IEEE 1584 calculation method was used, along with the guidelines in the 2015 edition of
NFPA 70E as a basis for this study.
Arc flash calculations require available three-phase bolted fault current values and protective
device clearing times. SKM utilizes the three-phase bolted fault values computed in the short
circuit study, and then determines arcing fault current. This arcing fault current is used to
determine protective device clearing time based on time-current curves issued by the device
manufacturer and stored in the SKM CAPTOR library.
The SKM Arc Flash module scans the entire system topology, starting from the faulted bus out,
to find the first protective device with an over-current trip curve. The upstream protective
device(s) was also included in the search by selecting the "Check upstream devices for miscoordination" option within the SKM Arc Flash module.
Upstream refers to the flow of power from the primary sources to the faulted location from the
perspective of standing at the fault location. If there are multiple contributions to the faulted
bus, the search process will be repeated until each contribution is cleared by its protective
device, or the search reaches the end of the topology.
Protection devices with a function name of "Ground" or "Neutral" were excluded from the
protective device search. Using the arcing fault current and protective device clearing time,
incident energy values are calculated by SKM based on IEEE 1584 and NFPA 70E standards.

SKM Arc Flash Module Calculation Assumptions
•

•

•
•
Arc Flash calculations were performed using the short circuit current calculated by Solar
City, and the values calculated by SCE. The worst-case incident energies from both cases
were used. Calculation results are listed in Appendix C, along with a note describing which
case produced the worst-case incident energy values.
The trip time is determined from the TCC curves stored in the SKM CAPTOR library for
all protective devices located in the branch that contains the faulted bus, and the device with
the fastest trip time for the given arcing fault current is used.
A constant working distance is assumed. The worker is stationary during the entire arc flash
incident.
When applying generic current-limiting fuse representation, the current-limiting range is
assumed to start where the fuse clearing curve drops below 0.01 sec.
When applying generic current-limiting fuse representation, fuses operating in the current
limiting range are assumed to clear in ½ cycle for currents 1 to 2 times the current where
the current-limiting range begins, and ¼ cycle for currents higher than 2 times the current
where the current-limiting range begins.
For purposes of the arc flash study, the interrupting device is rated for the available short
circuit current. No equipment damage is considered due to the available fault current
exceeding the protective device’s interrupting rating. Equipment that is underrated for the
available bolted fault current should be replaced with devices that meet or exceed the
available bolted fault current in order to prevent equipment damage and injury to personnel.
The next upstream protective devices were included in the search. The device that clears the
arcing fault fastest is used.
Ground fault and motor over load devices are excluded.
For multi-function protective devices, only time and instantaneous phase overcurrent
protective devices (ANSI devices 50 and 51) are used to determine the trip time.
Only the larger incident energy based on low or high protective device tolerances is
reported.
When the total fault current cleared is less than the threshold percent specified in the study
setup, or no upstream protective device is found, the bus is labeled as Dangerous and the
incident energy and flash boundary are not reported.
If the trip time obtained from the time current curve is larger than the maximum protection
trip time defined in the study setup, the maximum protection trip time is used.

Arc Flash Hazard Study Results
The following equipment had calculated incident energies above 8.0 cal/cm2. Incident energies
above 8.0 cal/cm2 require personnel to wear arc flash hazard suits with an arc rating that
matches or exceeds the incident energy calculated and printed on the arc flash warning label.

For all equipment, personnel must use PPE with an arc rating that meets or exceeds the incident
energy printed on the arc flash warning label. Note that the arc flash incident energies are valid
only when the recommended circuit breaker settings in Section 3.3 are applied.
The incident energies in the table above can not be reduced due to the impedance of
transformers TR-1 and TR-2 reducing the available fault current, which increases the time
required for protective devices to interrupt the arc. Incident energies at the equipment above
also can not be reduced due to the lack of adjustable settings on devices such as thermalmagnetic circuit breakers or fuses. The relatively high hazard risk category at TR-1 and TR-2
exists on the exposed 480V lugs. In the event of an arc flash on the transformer 480V lugs, the

transformer’s 12kV fuses would be called upon to interrupt the arc. The transformer’s
impedance results in a lower magnitude of fault current seen by the primary fuses, which
results in an increased opening time of the fuses, longer arc duration, and more heat energy
released from the arc. The Hazard Risk Category can not be reduced because the transformer
primary fuses have been selected by the manufacturer. The primary fuses must be properly
sized to accommodate the transformer’s inrush current. Smaller fuses may not withstand the
inrush current of the transformer. Replacement of the backup current-limiting fuses requires
transformer disassembly. Therefore, reduction of the Hazard Risk Category by changing the
protective devices is not feasible.
Installation of insulating shields over the exposed 480V terminals within the transformer
compartment will help prevent accidental contact with exposed energized parts, and reduce the
chances of an arc flash occurring within the transformer’s 480V compartment. Insulating boots
can be installed over the transformer lugs, or a sheet of insulating material such as fiberglass
could be installed in the compartment. Drop-on insulating boots that cover the transformer
480V terminals are available from manufacturers such as Thomas and Betts. The Arc Flash
Hazard at the transformer 480V terminals can also be avoided by de-energizing the transformer
from an upstream disconnect.
At PNL-1 and PNL-2, insulating shields that protect the terminals of the main circuit breakers
are available from Eaton/Cutler-Hammer, the manufacturer of the equipment installed as part
of this project. Insulating shields should be installed over the circuit breaker terminals if they
are not already provided from the factory.
Since the photovoltaic system will be tapped into the line side of Switchboard MSB main
breaker, there is no 480V protection at this tap. The tap, from the point of connection to the
1600A fused disconnect, should NOT be exposed while the systems are energized. Warning
labels advising against access to the tap while the system is energized should be affixed at the
point of the tap. Southern California Edison (SCE) should be contacted to disconnect service
prior to starting work on the tap at the line side of the 1600A disconnect. SCE requirements for
the interconnection of the photovoltaic system may require this tap to be sealed by the utility,
preventing access by facility personnel.
No energized work shall be performed on the service entrance equipment and conductors, or
the line side of the main circuit breaker. Contact Southern California Edison to perform deenergization of services before starting work on the line side of a service main circuit breaker.
In order for the Arc Flash Hazard study results to be valid, the recommended protective device
settings for the main circuit breaker should be programmed and tested by a qualified electrical
testing company.
Refer to Appendix C of this report for complete Arc Flash calculations performed at each
equipment location included in this study.

PROJECT RECOMMENDATIONS
1. Apply Recommended Protective Device Settings
It is recommended to program circuit breaker settings given in Section 3.3 of this report.
Applying the recommended protective device settings in Section 3.3 of this report will
provide optimal device coordination between the main and feeder circuit breakers, while
minimizing arc flash incident energies.
2. De-energized Electrical Work Policy
Establish the policy of working on electrical equipment that has been de-energized
whenever feasible. The directive for avoiding work on energized equipment is listed in
NFPA 70E - Standard for Electrical Safety in the Workplace -Justification for Work. “Live
parts to which an employee might be exposed shall be put into an electrically safe work
condition before an employee works on or near them, unless the employer can demonstrate
that de-energizing produces additional or increased hazards or is infeasible due to
equipment design or operational limitations.”
Working on electrical equipment that has been established as being in an electrically safe
condition, in accordance with NFPA 70E, Article 120, eliminates the Arc Flash hazard and
electrical shock hazard for most electrical equipment.
By working on de-energized equipment whenever feasible, the exposure of personnel to
Arc Flash and shock hazards is reduced.
3. Develop Arc Flash Hazard Management Program
1) PPE with a minimum Arc Thermal Performance Value (ATPV) of 8 calories is
recommended as daily wear for qualified employees routinely involved in electrical
maintenance.
2) PPE suitable for work on equipment with higher incident energies than 8 calories must
be provided.
3) Determine training requirements for various employee work responsibilities. Identify
qualified employees versus unqualified employees, and develop electrical safety
training tailored to the qualifications of employees.
4) Determine and publish Arc Flash Hazards Management Program policies.
5) Implement program.

EMWD/Arc Flash

4. Require and implement PPE and Protective Measure Policies against Arc Flash Hazards
Provide and require employees to practice and implement policies for use of proper
Personal Protective Equipment (PPE) for work in all areas of Arc Flash hazards, as required
by the facility Arc Flash Hazard Management Program. Qualified employees properly
wearing PPE according to the calculated incident energy will mitigate injuries experienced
by an arc flash.
“Employers must provide workers with appropriate PPE as per the OSHA 29 1910.132
(h)(1) PPE payment requirement, i.e., (PPE) used to comply with this part, shall be
provided by the employer at no cost to employees. Paragraph (h) became effective
February 13, 2008, and employers must implement the PPE payment requirements no later
than May 15, 2008.”
Provide clearly visible Arc Flash boundary markings so personnel know when they are
entering an Arc Flash zone and the PPE required prior to entering the Arc Flash zone
(movable cones, tape, etc.). Boundary markings will help prevent unqualified personnel
from entering an Arc Flash or shock hazard boundary while work is performed on
energized equipment.
5. Project Validation and Maintenance
In order to maintain a safe and compliant facility, it is imperative that the Arc Flash study is
updated as changes are made to the electrical distribution system. Changes in the electrical
system including impedance, protective device settings, and short circuit duties will affect
the incident energy values calculated in this report. As a result, changes in the electrical
system will invalidate these values.
Procedures for keeping this analysis up-to-date include, but are not limited to, updating the
single-line diagrams for the electrical distribution system, recalculating the Short Circuit
Study, the Coordination Study and the Arc Flash Hazard Assessment and updating the
equipment warning labels to incorporate the latest results. Perform a complete review of all
engineering studies performed as part of this Power System Analysis at a minimum of
every 5 years, or as required by future NFPA 70E requirements. The review should include
all recorded changes to the electrical infrastructure. If there are changes to hazard levels,
then equipment should be re-labeled appropriately.
Inaccurate incident energies and insufficient PPE can result in serious injury to personnel.
By keeping the Arc Flash Hazard Analysis valid and up-to-date, personnel can use proper
safety equipment to mitigate hazards. The risk of injury to personnel is minimized when
employees have the knowledge of the dangers in the workplace and utilize the right safety
equipment to diminish those dangers.

6. Provide Training of Arc Flash/Shock Hazards to Workers
Provide adequate training and rules governing the work and hazards on all electrical
equipment for both Qualified and Unqualified employees. Personnel must be adequately
trained to read Arc Flash/Shock hazard warnings and how to prepare themselves for the
dangers of an Arc Flash/Shock hazard.
By providing training, hazard notification, and PPE, the electrical system will be compliant
with OSHA and NFPA regulations regarding Arc Flash hazards as of this report date. The
risk of injury to employees as a result of shock/arc flash will be mitigated when employees
are aware of hazards and have taken necessary precautions for working on electrical
equipment, including, but not limited to, wearing proper PPE and establishing approach
boundaries.
7. Develop an Overcurrent Protective Device (OCPD) Management Program
Implement a comprehensive OCPD Management Program. Establish a Circuit Breaker
Maintenance program in accordance with manufacturer’s recommendations for testing and
maintenance. Require all future maintenance and replacement of fuses and circuit breakers
to use the same make and model number for replacement components.
The Arc Flash Hazard study depends on operation of the protective devices as shown on the
manufacturer’s TCC curves. These devices may be normally inactive for long periods. It is
essential that all protective devices and associated relays and sensors are tested and
calibrated at regular intervals, as recommended by the manufacturer.
The calculated Arc Flash hazard levels in the facility electrical distribution system are
dependent on the fault clearing times of the actual fuse types (UL Classifications) and
circuit breaker types and their trip settings installed in the system. All maintenance changes
to OCPDs must be recorded in writing, i.e., red-lined drawings and drawing revisions. In
order to maintain the integrity of this Arc Flash Study, all changes to OCPDs will require
future re-calculation of incident energy levels to determine new hazard levels.
OCPD coordination in the electrical distribution system is dependent on the fuses, circuit
breakers and trip settings currently installed, and recommended. Replacement of protective
devices with units that are not identical will affect system protection device coordination,
and may adversely affect incident energies calculated in this report.
A documented program of scheduled circuit breaker testing and maintenance will ensure
that the circuit breakers are in operational condition and that they will function properly
during a short circuit condition. Periodic testing of circuit breakers and associated relays
ensures proper operation of the circuit breaker’s protective function. Without circuit breaker
maintenance, Arc Flash Hazards can increase significantly over time due to slow opening
response times of dirty or worn mechanisms, even with no changes to the electrical system.

8. Equipment Maintenance
Buildup of debris in equipment enclosures poses a risk of a short circuit, flashover, and/or
equipment failure. In addition, electrical connections can become loose over time. Loose
electrical connections can cause high-resistance heating of conductors and connecting
devices, and pose a fire hazard. The protective device operating mechanism must be
lubricated and exercised to assure proper operation. Periodically de-energize and operate
protective equipment and perform maintenance as recommended in 2013 NFPA 70B,
“Recommended Practice for Electrical Equipment Maintenance.” Clean interior of
equipment enclosures. Check bolted connections for proper torque, that all electrical
connections are secure, and perform any other maintenance per manufacturer’s instructions.
Maintain a log of maintenance and inspections performed.

EMWD/Arc Flash

APPENDIX C
ARC FLASH CALCULATIONS
A table of arc flash calculations performed at each equipment bus is included on the following pages.
The columns in the table are described as follows, reading from left to right:
Bus Name
Fault location for report. For line side and load side report options the bus refers to the equipment
where the line side and load side protective devices are connected.
Protective Device Name
Lists the protective device that clears the arcing fault.
Bus kV
Bus voltage at the fault location, given in kilo-volts.
Bus Bolted Fault Current (kA)
The magnitude of current flowing to a bus fault that occurs between two or more conductors or bus
bars, where the impedance between the conductors or bus bars is zero.
Bus Arcing Fault (kA)
The calculated arcing current on the faulted bus.
Protective Device Arcing Fault Current (kA)
The arcing fault current flowing through each protective device feeding the arc fault. Note that the
total arc fault current may flow through several parallel sources to the arc location.
Trip / Delay Time
The time required for the protective device to operate for the given fault condition. In the case of a
relay, the breaker opening time is entered separately from the relay trip time. For fuses, the trip time is
assumed to be the total clearing curve or high tolerance of the published clearing curve.
Breaker Opening Time
The time required for a breaker to open after receiving a signal from the trip unit to operate. The
combination of the Trip/Delay time and the Breaker Opening time determines the total time required to
clear the fault. This column does not apply when a fuse operates to clear the fault.
Duration of Arc
The summation of Trip/Delay Time and Breaker Opening Time.
Arc Type
Identifies whether the fault location is in an enclosure or in open air. In open air the arc energy will
radiate in all directions whereas an enclosure will focus the energy toward the enclosure opening. The
In Box / Air selection is available when the NFPA 70E study option is selected. For the IEEE 1584
Page C - 1
September 30, 2015
PES No. 4863B-15
EMWD/Arc Flash
Temecula Valley RWRF
study selection the In Box or In Air is determined automatically from the Equipment Type
specification.
Arc Flash Boundary
The distance from exposed live parts within which a person could receive a 2nd degree, curable, burn.
Working Distance
The distance between the arc source and the worker’s face or chest.
Incident Energy
Incident energy is calculated in calories per square centimeter (cal/cm2). This value is a function of
working distance, system voltage, available bolted fault current, arc current, and the time required for
circuit protective devices to clear the fault and extinguish the arc.
Required Protective FR Clothing Category/PPE Level
Level of Personal Protective Equipment (PPE) necessary to protect a person from the Arc Flash energy
calculated for the specific location and working distance.

Definition
A pressure wave created by the heating, melting,
vaporization, and expansion of conducting material and
surrounding gases or air.
The sudden release of heat energy and intense light at the
point of an arc. Can be considered a short-circuit in the air,
usually created by accidental contact between live
conductors.
A study that analyzes potential exposure to Arc flash hazards.
The outcome of the study establishes Incident Energy levels,
Hazard Risk Categories, Arc Flash Protection Boundary and
required level of PPE.
A protection boundary established to protect personnel from
Arc flash hazards. This boundary is the distance at which an
unprotected worker can receive a second-degree burn to bare
skin.
Arc Thermal Performance Value which is defined in ASTM
F 1959, Standard Test Method for Clothing, as the incident
energy on a material or multilayer system of materials that
result in a 50% probability that sufficient heat transfer
through the tested specimen is predicted to cause the onset of
a second degree skin burn injury based on the Stoll curve,
cal/cm².
The amount of heat needed to raise the temperature of one
gram of water by one degree Celsius. 1 cal/cm² is equivalent
to the exposure on the tip of a finger by a cigarette lighter for
one second.
A device that, when interrupting current in its current limiting
range, reduces the current flowing in the faulted circuit to a
magnitude substantially less than that obtainable in the same
circuit if the device were replaced with a solid conductor
having comparable impedance.
Equipment or components that have had all possible energy
sources removed.
A dangerous condition caused by equipment failure or
contact with an energized conductor or circuit part. Hazards
include shock, Arc flash, burns and arc-blast.
A study to identify the potential electrical hazards that may
be exposed to personnel. The assessment should address both
shock and Arc flash hazards.

principles and safe work practices to protect workers exposed
to electrical energy.
The property of material whereby combustion is prevented,
terminated, or inhibited following the application of a
flaming or non-flaming source of ignition, with or without
subsequent removal of the ignition source. Flame resistance
can be inherent to the material or applied by a specific
treatment.

A means of classifying the hazard to personnel as defined by
NFPA 70E. Each category (0-4) requires PPE and is related
to incident energy levels.
The amount of thermal energy impressed on a surface
generated during an electrical arc at a certain distance from
the arc. This is typically measured in cal/cm².
The highest rms symmetrical current, at specified test
conditions, which the device is rated to interrupt. The
difference between Interrupting Capacity and Interrupting
Rating is in the test circuits used to establish the ratings.
An approach boundary to protect personnel from shock. A
boundary distance is established from an energized part based
on system voltage. To enter this boundary, unqualified
persons must be accompanied by a qualified person and must
use PPE.
Energized electrical conductive components or circuit parts
Equipment used to protect personnel which can include
clothing, tools, etc.

Definition
An approach boundary to protect personnel from shock.
Work in this boundary is considered the same as making
direct contact with an energized part. Only qualified persons
are allowed to enter this boundary and they must use PPE.
This analysis will determine the opening time of the
protective devices relative to the time-current curves as
issued by the fuse and/or circuit breaker manufacturer.
Protective device settings are recorded and recommendations
are provided for better protective device coordination (where
applicable).
One who has the skills and knowledge related to the
construction and operation of the electrical equipment and
installations and has received safety training to recognize and
avoid the hazards involved.
An approach boundary to protect personnel from shock. A
boundary distance is established from an energized part based
on system voltage. Only qualified persons are allowed to
enter this boundary and they must use PPE.
A trauma subjected to the body by electrical current. When
personnel come in contact with energized conductors, it can
result in current flowing through their body often causing
serious injury or death.
A study that analyzes potential exposure to electrical Shock
hazards. The outcome of the study establishes circuit voltage
and shock protection boundaries.
The prospective symmetrical fault current at a nominal
voltage to which an apparatus or system is able to be
connected without sustaining damage exceeding defined
acceptance.
A study which analyzes and determines the available phase
and ground fault duties for all buses and equipment. The
analysis outputs will indicate fault currents available and
device interruption ratings required at each bus. Any
equipment which is not rated for the available fault current is
also identified.
A diagram that shows, by means of single lines and graphic
symbols, the course of an electric circuit or system of circuits
and the component devices or parts used in the circuit or
system.
A person that does not possess all the skills and knowledge or
has not been trained for a particular task.
Closest distance a worker’s body, excluding arms and hands,
would be exposed to the arc.
