ELECTRICAL MAINTENANCE
Equipment Planned Maintenance System
Maintenance Duties (MD)
SECTION 1 – INTRODUCTION
1. 1 BACKGROUND
Without proper maintenance, the safety and integrity of equipment/plant can not be ensured
even if the equipment/plant has been designed and manufactured with due consideration to
health and safety.
The Occupational Health and Safety Act (the Act) and Occupational Health and Safety (Plant)
Regulations 1995 place an obligation on employers to ensure equipment/plant is maintained.
The Act also requires employers to provide and maintain, so far as is practicable, a working
environment that is safe and without risks to health for employees who undertake inspection
and maintenance work.
1.2 MANAGERS OVERVIEW
Electrical Safety is of the utmost importance in our stores. This manual describes electrical
maintenance duties in formats i.e. Maintenance Duties (MD501) which can be carried out by
Gloria Jean’s Coffees personnel and qualified technicians, and Qualified Technician
Maintenance Duties (QMD501) which can only be carried out by a qualified technician. The
document outlines the in-service electrical tasks considered necessary for both the store (MD
501) & tasks for the licensed electrical contractor (QMD 501) as minimum planned
maintenance to ensure the safety of person(s) using electrical equipment.
Electrical equipment is required to be inspected tested & tagged to Australian Electrical
Standard (AS3760) by a qualified & certified personnel on an Annual & Bi Annual basis to
detect unsafe conditions. This is to ensure we take reasonably practicable steps to ensure that
no danger results from the use of such equipment. This in effect, requires the implementation
of a systematic and regular program of maintenance, inspection and testing.
It is the Franchise Partner or Store Manager’s responsibility to co-ordinate the Electrical
Contractor to schedule this work.
All of the required inspections & checks that are outlined in this manual shall not remove the
responsibility from the personnel carrying out the works to undertake procedures in accordance
with requirements within the relevant state specific Occupational Health and Safety Legislation,
and Australian Standards for in-service safety inspection and testing of electrical equipment /
appliances / plant.
The Electrical Planned Maintenance Qualified Technician Tasks (QMD501) includes various
inspections that need to be completed by a Licensed Electrical Contractor. A licensed electrical
contractor will ensure correct diagnostic of faults & legal remedial works in store. Your electrical
contractor should already be familiar with and practising these tests & procedures that need to
be applied to our stores for the provision of a ‘safe place’. The electrical contractor should have
a current copy of the relevant Standards. The in store inspection procedures are mandatory.

ELECTRICAL MAINTENANCE
Equipment Planned Maintenance System
Maintenance Duties (MD)
On completion of the checks, the original signed copy of the report sheet/book must be given to
the store manager and filed in section 5 of the OH&S manual within the store premises. The
report sheet will outline inventory of all electrical equipment tested by description a list of failed
items, new repaired items log and next due date. The manager is required to record completed
tasks on completion and in accordance with the Gloria Jean’s Coffees Daily Book - Equipment
Planned Maintenance Yearly Schedule.
This manual must be stored in the Equipment Planned Maintenance Binder which forms part of
the Operations Standards Manual within the store & shared with your approved electrical
contractor for their review.
1.3 ELECTRIC SHOCK
Electric shocks caused by electrical equipment occur without warning and are often serious.
The severity of the electric shock can range from a tingling sensation to electrocution and
death, the factors which affect the severity of electric shock are the :(a) value of shock current
(b) time for which it flows
(c) the path through the body
1.4 IN – STORE INSPECTION
As a manager you are required to inspect electrical cords regularly, the things to look for when
carrying out a visual check are as follows:(a) frayed or split outer casing
(b) badly worn, perished or kinked insulation
(c) ensure that any lead is mechanically secured at termination
(d) chipped, cracked, discoloured or broken fittings
Additionally, you are required to visually inspect and detect any adverse condition to any
electrical apparatus observed to be unsafe and or faulty, such as exposed electrical
components & wiring. Examples of electrical apparatus to which this applies but not limited to
are:- power outlets, lighting & fittings, switches, equipment, plant, switchboards, computers,
monitors, air conditioner, vacuum cleaner, power tools, electric water urns / heaters, insect
traps, coffee bean grinders, ice machine, coffee, espresso machines, toasters, grillers,
microwave, hand dryers, dishwasher, refrigerated & ambient pastry display cabinets, garbage
compactor, refrigerated & freezer cabinets, beverage mixers, bean bar scale, brewer, music
hard drives & system, register, refrigerated beverage whipper dispenser.
Do not operate equipment if it has a damaged cord or plug; if it is not working properly, or if it
has been damaged or dropped. Faulty electrical equipment / plant can also lead to fires, which
may also cause death or injury to others. Report any such defect.

ELECTRICAL MAINTENANCE
Equipment Planned Maintenance System
Maintenance Duties (MD)
It is best practice to have your Licensed Electrical Contractor visually check all lighting
equipment, luminaires diffusers for correct position and integrity. Replace all damaged diffusers
and defective lamps. Other electrical lighting components which may require replacing will be
done by the licensed Electrical Contractor or qualified technician.
No person should attempt to repair any electrical equipment unless qualified to do so.
1.5 REPAIR OF ELECTRCAL EQUIPMENT & PLANT
If the equipment is found faulty it must be immediately disconnected from the energy source by
unplugging the power supply lead by the plug body only, isolate & withdraw from service.
Equipment is required to be labeled by the person carrying out the inspection to warn against
further use until repaired by authorised service agent or service personnel. In the event the
equipment is deemed permanently inoperable then dispose of or destroy.
At no time should you re-activate tripped Residual Circuit Breaker Device (RCD) or Earth
Leakage Circuit Breaker (ELCBs). Immediately place service call to qualified electrical service
personnel or authorised equipment service agent. Failure to do so may result in electric shock
and/or further damage to electrical components that may fail to continue to operate effectively
as per design or fail to provide protection against electric shock.
Equipment should be serviced by qualified personnel only. Contact the Supplier for
adjustment or repair.
1.6 PROTECTION
A Residual Current Device (RCD) is a device intended to isolate the circuits connected to it in
the event of a predetermined current flow to earth. RCDs are also known by other names Earth
Leakage Circuit Breaker (ELCB).
All power outlets, portable equipment and kitchen equipment must be protected by an Earth
Leakage Circuit Breaker (ELCB) or Residual Current Device (RCD). Display RCD sign
whenever RCD is fitted in the vicinity of the distribution board / switchboard as required by local
council regulations.
It is necessary for the Electrical Contractor or authorised service personnel to verify an RCD
has operated due to an earth fault when responding to a service call. It is necessary for the
authorised service personnel to be satisfied that an earth fault does not exist and the
equipment has been serviced. Additionally, the RCD is required to be tested with the correct
equipment confirming that it still operates as designed.

MD501
ELECTRICAL MAINTENANCE
Equipment Planned Maintenance System
Maintenance Duties (MD)
An RCD installed at a workplace must be kept in good working condition and be tested on a
regular basis by a competent person to ensure its continued effective operation. A record
should be kept of these tests. A “competent person” is someone who is an individual who, by
way of training and/or experience, is knowledgeable of applicable equipment, is capable of
identifying workplace hazards relating to the specific operation, is designated by the employer,
and has authority to take appropriate actions.
RCDs will not protect against all electrical incidents; for example RCDs will not protect against
the serious shock situation where a person contacts both active and neutral conductors without
current flowing to earth.
RCDs are an addition to safety measures not a substitute for them.
1.7 FREQUENCY OF ELECTRICAL
CONDUCTED BY STORE
PLANNED
MAINTENANCE
INSPECTION
Monthly
•
Check the operation of each exit and emergency light by depressing the “test” pushbutton
on each fitting and checking whether the light changes to battery supply.
•
Any incorrect operation must be reported to the Store Manager and any faults remedied.
•
A monthly inspection of all lights to determine whether any lamps or fluorescent starters
have failed. Replace all readily accessible failed lamps or starters provided that they are
not damaged.
Note: Any lamp failures noticed at other times should be rectified as they occur.
•
Special note is to be taken that tungsten halogen lamps must not be touched with bare
hands as the acid from the skin will deteriorate the quartz glass envelope of the lamp.
•
Other than replacement of lamps and readily accessible starters it is recommended that all
other light fitting maintenance be carried out by fully qualified licensed electricians.
Note: Polished lighting diffusers should not be touched with bare hands as finger prints are
often difficult to remove. Cotton gloves should be utilized when cleaning or handling
polished diffusers.

SECTION 5 – ELECTRICAL MAINTENANCE INSPECTION AND
TESTS:
All Tasks Must Be Performed by Qualified Technician Only
Warning Electrical Shock Hazard
Potential hazards and cautions may be exposed during these procedures. Follow safe
working practices and procedures to control the hazards.
5.1 ELECTRICAL TAGS
On completion of each safe test / inspection, durable, non-metallic, non-reusable tags robust
enough for our environment are required to be attached to each individual piece of equipment to
verify that the equipment has been checked, tested & passed. The integrity of the tag is required to
be maintained given our aggressive environment.
Tags must contain all necessary information including due date of the next inspection. This will be
noted on the tag as well as electrical contactors details.
Where the equipment test as safe, a tag needs to be attached to the power lead within 300mm of
the plug end by way of black nylon cable tie or fastening system fit for purpose once the equipment
has passed its inspection prior being placed back in service.
5.2 REMEDIAL WORKS & ACTION
All remedial works should be completed in accordance with AS3760 & AS3000
Locking out of equipment is the most effective way of preventing it from becoming operational
during maintenance or failure. If any work is to be carried out on a particular piece of equipment
and there is a possibility of somebody inadvertently turning it on, the qualified person carrying out
the work must personally fasten a red and black "DANGER" tag or lock to the main isolating switch.
In the event that the electrical contractor shall remove from operation any equipment found to be
faulty and tag “Caution – Do not operate” on the equipment or attached to the relevant circuit
breaker if the equipment is permanently fixed wired
As a result of the electrical inspection or checks, the electrical contractor is required to record on
the report sheets any remedial work, defects and action taken. Defects require immediate action
before equipment can be placed back into service. This needs to be reported to the Store Manager
who will log the defect & arrange for the immediate action.

vii) Thermal Scan of Main Switchboard(s) and associated report. This test is to be done when
the switchboard is fully loaded for at least 2 hours with all air conditioning running. Note:
This test is required only when the switchboard is heavily loaded near its capacity or
shows signs of heating problems.
viii) The recommended period for the above check - minimum annually.
ix) All maintenance is to be carried out by fully qualified licensed electricians.
x) If a fault has occurred on the switchboard or a circuit has tripped the cause of the fault
must be determined and rectified prior to re-commissioning the switchboard or re-closing
the circuit. Thorough maintenance of the switchboard will be required and the tripped
component fully checked prior to its re-commissioning. If there is any doubt as to the
condition of any component after any fault, the component is to be replaced.
xi) Whenever annual maintenance is carried out, spot load checks should be done on all
major circuits with a tong tester and the results recorded. Any circuits that are approaching
80% of the rated load should be reported to the building manager. Any circuits exceeding
80% of the rated load must be carefully checked to ensure overheating of any components
does not occur.
5.6.3 DISTRIBUTION BOARDS (DB) [IF APPLICABLE]
Maintenance
Maintenance is generally similar to the maintenance described for the main switchboard, but does
not require the shut down of the site power supply. However the supply to each distribution board
should be isolated while maintenance is being carried out. A thermal scan is only required if:
i)
ii)
iii)
iv)
There is any doubt about the condition of a DB
The DB has been subject to a fault and put back into service
The DB is rated at least 100amps and is more than 5 years old
The DB is fully utilised
Distribution Boards generally incorporate moulded case circuit breakers and residual current circuit
breakers (earth leakage circuit breakers) for circuit protection. Some DB’s also incorporate
contactors, relays and time switches for the control lighting.

Qualified Maintenance Duties (QMD)
In addition to the general maintenance of distribution boards (DB’s), the operation of residual
current circuit breakers should be tested by pressing the test button on each circuit breaker and
resetting the breaker by placing the circuit breaker switch in the ‘ON’ position. Note: it may be
necessary to first place the circuit breaker in the ‘OFF’ position, before switching to ‘ON’.
In addition to the above, check that a circuit schedule is attached to the inside of the door of the
DB, that it is accurate and typed in a neat and tidy manner. Amend and/or replace as necessary.
5.6.4 TESTING OF RCD’S
•
As described in clauses 5.4 & 5.6.3
5.6.5 EMERGENCY AND EXIT LIGHTS
Emergency and exit lights are of the single point type where each light has its own integral battery
pack and charger unit.
The battery charger for each light is fed from an un-switched active (other than the switching
provided by the emergency and exit lighting test facilities) originating at the lighting circuit feeding
the same general area of the emergency or exit light. In this way the batteries are being charged at
each fitting at all times.
The initial capacity of the battery for any newly provided emergency or exit light is 2 hours for the
first 12 months and 1 ½ hours thereafter i.e. the battery will initially operate the light for 2 hours if a
power failure occurs. After 12 months the battery capacity is expected to reduce to 1 ½ hours. This
is the minimum acceptable period after 12 months. After a total discharge it takes approximately 16
hours for the batteries to fully recharge.
The life of each battery is in excess of 2 years.
Each emergency and exit light has a ‘test’ pushbutton and a light emitting diode (LED). The LED
illuminates when the light is on normal power and the battery is charging.
An emergency and exit lighting test circuit has been provided with every distribution board
providing power to emergency and exit lights. The circuit has the following features:
•
•
•
‘Test’ pushbutton (or key switch) and ‘Test’ indicator
0-2 hour timer
‘Reset’ pushbutton

QMD501
ELECTRICAL MAINTENANCE
Equipment Planned Maintenance System
Qualified Maintenance Duties (QMD)
When the ‘test’ (or key switch) pushbutton is operated the emergency and exit lighting circuit from
that DB simulates a power failure and the emergency and exit fittings operate via the battery pack
within the fittings. The test runs until the timer automatically resets the system onto mains power
and the normal mode.
Note: The timer should be set for 2 hours (120 minutes) for the first 12 months after building
commissioning and for 1 ½ hours (90 minutes) thereafter.
Should the test need to be interrupted, the ‘reset’ button can be pushed and the system will return
to normal mode of operation.
The following maintenance should be carried out:
Bi-Annually
a)
•
Visual inspection of all lights for any signs of deterioration, damage or failures and any
faults remedied.
•
Full 2 hour discharge test in the first 12 months and 1 ½ hours thereafter of the lights by
operating the emergency and exit lights test circuit in each DB and checking whether the
batteries operate the fitting for the full 2 hours (1 ½ hours after 12 months). Any fitting that
does not provide the 2 hours (or 1 ½ hours) operation should have the batteries replaced.
•
The Emergency Lighting Log Book (as required by AS2293) should be filled in after the full
2 hour (or 1 ½ hours) discharge test. This log book is normally kept in the main switch
room/building manager’s office/security room.
Annually
b)
•
Visual inspection of all lights for any signs of deterioration, damage or failures and any
faults remedied.
•
Full 2 hour discharge test in the first 12 months and 1 ½ hours thereafter of the lights by
operating the emergency and exit lights test circuit in each DB and checking whether the
batteries operate the fitting for the full 2 hours (1 ½ hours after 12 months). Any fitting that
does not provide the 2 hours (or 1 ½ hours) operation should have the batteries replaced.
•
The Emergency Lighting Log Book (as required by AS2293) should be filled in after the full
2 hour (or 1 ½ hours) discharge test. This log book is normally kept in the main switch
room/building manager’s office/security room.

A Fire Safety Statement of Compliance for the emergency lighting should be forwarded to
the local council as required by the local council.
Notes:
1. When a test arrangement is not provided, each lighting circuit which feeds emergency and
exit lighting must be tested by opening the circuit breaker feeding that lighting circuit.
2. Any emergency lighting circuit that only feeds emergency and exit lights is incorrect as
emergency/exit lights must be fed from the local general lighting circuit and from the line
side of any light switching. Any incorrect arrangement must be corrected.
5.6.6 GENERAL LIGHTING INSTALLATION
The following maintenance is to be carried out:
a) Annually
b)
•
Cleaning of all light fittings including reflectors and diffusers.
•
All components should be checked and any defective components replaced including
damaged diffusers and noisy ballasts.

Special note is to be taken that tungsten halogen lamps must not be touched with bare
hands as the acid from the skin will deteriorate the quartz glass envelope of the lamp.
•
Other than replacement of lamps it is recommended that all other light fitting maintenance
be carried out by fully qualified, licensed electricians.
•
Polished lighting diffusers should not be touched with bare hands as finger prints are often
difficult to remove. Cotton gloves should be utilized when cleaning or handling polished
diffusers.

Qualified Maintenance Duties (QMD)
a)
Visual inspection as follows:
• Check all accessories for damage or deterioration.
• Check that all GPOs and switches are correctly marked with the relevant circuit number.
• Replace/repair defective components and correct or add markings as necessary.
b)
Operational check of accessories as follows:
• Check that light switches operate crisply and that there is no undue arcing during operation
• Check that GPOs and socket outlets operate
• Check that pushbuttons operate
• Check that isolating switches operate
• Repair or replace any components that are defective.
In particular, light switches controlling fluorescent lighting circuits must be checked for operation.
Unless the action is normal and crisp, damage may have occurred due to switching transients.
Replace any suspect switches. The replacement switches for fluorescent light loads should be a
type that is designed to cope with fluorescent light transients. Clipsal switch mechanisms 30FLM,
30FLM15 and 30MD20 are suitable.
5.6.8 MAINS AND SUBMAINS
a) Mains
Mains to Gloria Jean’s Coffees are reticulated from the supply authority or the building main
switchboard to the Gloria Jean’s Coffees main switchboard.
All maintenance is to be carried out by fully qualified licensed electricians.
The following maintenance is to be carried out:
Determine whether any deterioration or damage has taken place by completing a visual inspection
of the entire length of the cables. Repair any damage or if not repairable arrange to replace the
damaged cable.
Check that all cable strapping is tight and that all cable ties have been cut short. Tighten or replace
any strapping that has become loose or untidy.
Check the connections at both ends of each cable core. Tighten any that have become loose.
Isolate the supply and carry out an insulation resistance test with a suitable megger. The reading
should not be less than 3 megohm. If less than 3 megohm investigate the cause and correct.
