Importance of Emergency Power
Emergency preparedness and
recovery are critical components
to safeguarding our communities.
THE COST OF POWER
The monetary impact of power outages on 679 US businesses
Year after year, we are reminded
of how dependent we have
become on the underlying
infrastructure that delivers the
clean water, electricity, and
communications we often take for
granted. It is only after a
hurricane, tornado, flood, ice storm
or earthquake has knocked out our
utility systems that we realize the
ramifications of losing access to
these fundamental services.
Billion Dollar Climate Disasters by State 1980 - 2013¹
The graphs to the right illustrate an
unmistakable rise in the number of
natural disasters, as well as their
increased intensity.
There is often a large cost impact
for businesses without backup
power in the event of an extended
utility power outage; municipal
facilities without power can cause
severe social problems. Being
diligent and taking appropriate
steps to minimize operational
downtime is good
business practice. While some
standby power solutions can
be quite costly, ESL’s pre-wired
emergency power connection
equipment is very cost-effective
when comparing all the separate
pieces of alternate solutions. In
addition, our emergency power
products provide users with safe
and simple operation so that gridtied facilities can quickly connect
to portable power.

Manual Transfer Switch
70A – 800A Wall Mount
ESL’s UL/cUL 1008 Listed StormSwitch
manual transfer switch is the ideal solution
for portable generator connection to gridtied facilities. StormSwitch combines a
robust commercial-grade transfer switch
with color-coded cam-style connectors
for quick connection to a portable power
generator. Integral utility and generator
manual disconnects are interlocked to prevent cross connecting the power
sources. Once installed by a licensed electrician, the StormSwitch is so
easy and safe to operate that only basic training is required. Buying and
installing automatic transfer switches with a permanent generator for
each site can be quite costly and requires ongoing maintenance. With
StormSwitch, multiple locations can be equipped with a manual transfer
switch and share a single portable generator, a significant cost savings.

3-way Manual Transfer Switch
125A - 800A
Load bank testing can be challenging and
time consuming. In addition, the process
leaves critical operations systems
(COPS) susceptible to power loss during
testing since the permanent generator
has been disconnected from the system.
ESL’s TripleSwitch is a dual purpose
solution to service critical operations
facilities that utilize an automatic transfer
switch and permanent generator. The
TripleSwitch provides three interlocked
disconnects to isolate standby generator circuits during load bank testing,
while providing the additional benefits of ESL’s StormSwitch manual
transfer switch. This ensures that a quick, safe method to connect to
a portable generator for redundant backup power is available. ESL’s
TripleSwitch combines generator quick connects for redundant backup
portable power at a much lower cost, smaller footprint, and can virtually
eliminate wiring mistakes.
Cost Advantages of the TripleSwitch:
• Man power to run testing process is reduced
• Reduction of testing set-up and disconnect time
• Prevents costly repairs of stripped lugs on permanent
generator
• Provides a redundant and safe way to
connect a backup generator in the event the
permanent generator malfunctions, requires
routine maintenance repairs, or if utility power
to your facility fails during load bank testing

Outlet Box
400A - 1600A Without Circuit Breaker
125A - 2000A With Circuit Breaker
ESL’s Outlet Boxes are designed to provide end users a safe and simple method of taking power from a
facility’s power source and distributing it to exterior electrical equipment via 400A cam-lock cables in lieu of
utilizing a portable generator. Outlet boxes are simple pass-through boxes that are mounted to the exterior
of a building and wired to an existing power source. These boxes can be designed with or without a breaker
based on your facility needs, and provide operators with color-coded female cam-style receptacles to ensure a
quick and safe connection. In addition, if your facility has an available breaker up stream, outlet boxes can be
designed to include a dead switch to the main utility breaker on the door for added safety. Utility breaker would
be manually reset after device connection.

Why UL 1008 Should Be Specified
When comparing NRTL Listings of different products, it is important to know what the appropriate UL standards are and how
they apply to your specific application. You may not always be purchasing what you think you are. UL 1008 is specifically
designed for transfer switch equipment. Products with a UL 1008 certification means the whole assembly is certified and has
undergone rigorous testing to ensure performance, safety, and reliability. Non-Automatic transfer switches that are Listed
under the UL 1008 standard are evaluated in accordance with Articles 517-Health Care Facilities, 702-Optional Standby
Systems of the National Electrical Code (ANSI/NFPA 70) and the National Fire Protection Association Standard for Health
Care Facilities (ANSI/NFPA 99). The inspection process is also easier when emergency power transfer switch equipment is
UL 1008 Listed.
Frequently Asked Questions
What are the advantages/
disadvantages of using a manual
transfer switch with a portable
generator versus an automatic
transfer switch with a permanent
generator?
Advantages:
• Significantly lower cost
• No on-site fuel storage required
• No maintenance or standard
periodic testing
• Easier installation – days instead
of weeks
• Smaller size
• Portable generator can be rented
or used at other facilities
• Does not require multiple permits
that a permanent generator would
Disadvantages:
• Longer time before generator
power is established
What is UL 1008 and how does it
affect me?
Local building inspectors typically
require all new electrical equipment
installed in their jurisdiction to be
“Listed” which means the equipment
has been approved by Underwriter
Laboratories or another recognized
test lab. For standby systems that
allow portable generator connection,
UL 1008 is the proper standard for
manual transfer use. If the equipment
is not Listed, it may not be acceptable
to the inspector.
Can’t I just connect my generator
directly to my panel?
Accidentally backfeeding the utility
grid can be very dangerous. For a
direct connection you would need
a Certified Electrician available
anytime you needed to hook up your
generator. There are other methods
©2014 ESL Power Systems, Inc. All Rights Reserved. www.eslpwr.com
and products available for powering
up from a portable generator, but
the StormSwitch is the best product
available that combines the simplicity
of cam-style connectors with a safety
interlock device that prevents back
feeding the utility grid.
Can vandals open or steal the
StormSwitch? Can they shut off my
power?
Once installed, the device is always
in use. The StormSwitch door can be
padlocked, preventing unauthorized
entry. The disconnect handles
can be padlocked in the “OFF”
position for further security. With a
minor modification, the disconnect
handles can also be padlocked in the
“ON” position, however, this is not
recommended. For complete security
the StormSwitch is equipped with
a lockable handle cover to prevent
unauthorized use.
Where can I make conduit
penetrations on the StormSwitch?
Conduit line/load penetrations can
be made around the top portion of
the enclosure (top left, top right, top
back, top top) and/or bottom left of the
enclosure only. For the StormSwitch
BeBe, conduit line/load penetrations
can only be made through the bottom
left side of the enclosure.
Can the StormSwitch be Service
Entrance Rated?
Yes, the StormSwitch has the option
to be SUSE (Suitable for use as
Service Entrance in the USA). This
option should only be used when the
StormSwitch is installed at the building
service entrance.
I am in Texas. Can the StormSwitch
survive the rain/heat/cold/bugs
here?
The StormSwitch is a Type 3R
enclosure. This means it is suitable for
outdoors and will protect components
from rain. To ensure that insects,
debris, small animals do not enter
the enclosure, ESL provides a hinged
cover over the cam openings in the
bottom of the enclosure that is locked
closed when the door is shut.
What is the TripleSwitch designed
to do?
The TripleSwitch was designed to
simplify and reduce the cost of load
bank testing procedures in addition
to providing a backup for the backup.
This unique 3-way manual transfer
switch system provides a quick
and completely safe way to supply
power to the facility from a portable
emergency standby generator during
load bank testing in the event the utility
power is disrupted due to a power loss
or if the permanent generators are
offline.
Is it difficult to make the generator
connection to the StormSwitch,
TripleSwitch or TempTap product
line?
No, they utilize the industry standard
400A series 16 cam-style connectors.
ESL’s StormSwitch, TripleSwitch
and TempTap are color-coded to the
voltage, e.g. 208Y/120 green, white,
black, red, blue.
How do I know what product will
best work with my specific needs?
ESL’s knowledgeable sales personnel
will gladly assist with helping to identify
the proper product for your application.
The key factors will be the voltage
system and the desired emergency
load that is to be fed.
