SAFETY
IMPORTANT SAFETY INSTRUCTIONS
lTheNational ElectricalCoderequirestheuse ofatransfer
switch or other suitable transfer equipment whenever a
portable generator is connected to a building’s electrical
system. Transfer switches isolate generator power from
utility power and prevent backfeeding of electric power
into the utility system.
DANGER
Fire and electrocution hazard.
DO NOT connect to a building’s electrical system
unless the generator and a transfer switch have
been properly installed and the electrical output
has been veried by a qualied electrician. The
connection must isolate the generator power from
utility power and must comply with all applicable
laws and electrical codes. Failure to properly isolate
the generator power could cause property damage
and create a dangerous backfeed of electricity
which could kill or seriously injure utility workers.
WARNING
Use approved transfer
switches and equipment to isolate generator power
from utility power. Using non-approved transfer
switches can result in death, serious injury, and
equipment damage.
lInstallation and maintenance of this transfer switch must
be performed by a qualied electrician in accordance
with applicable electrical codes. Some jurisdictions
may require the installation to be inspected by local
authorities. Keep all relevant installation, inspection,
and maintenance information.
WARNING Using transfer switches that
are improperly installed and maintained could result
in electrocution or re, which can cause death or
serious injury.
DANGER
Do not wire or operate the
transfer switch or any electrical equipment while
barefoot, with wet hands or feet, while standing in
water or in wet conditions. Doing so will create a
dangerous electrical shock hazard that will result
in death.
DANGER
Handle transfer switches
with care during installation. Never mount or wire
a damaged transfer switch. A damaged transfer
switch could malfunction and create electrical
hazards that could result in death, serious injury,
and equipment failure.
WARNING
Only licensed and qualied
professional should wire and install transfer
switches. Improper installation can result in death,
serious injury, and equipment or property damage.
lAlways ensure that the main circuit breaker in the load
center is in the OFF position before installing the transfer
switch, changing the electrical source, or performing
maintenance.
DANGER Risk of Electrocution. Turn the
main circuit breaker in the load center OFF before
connecting circuits to the transfer switch. Contact with
live terminals will result in severe electric shock,
personal injury, and death.
DANGER
In case of an electrical
emergency, immediately shut the power OFF. If
necessary, separate the victim from live conductors
using non-conductive items like a PVC pipe or wooden
broomstick. If the victim is unconscious administer rst
aid and get medical assistance immediately. Failure
to act promptly will result in death or serious injury.

ELECTRICAL
CHOOSING LOAD AND TRANSFER
CIRCUITS
lWith the help of a qualied electrician, decide which
branch circuits inside the load center will use generator
power when the switch is operational. Choose up to six
circuits that include 120V appliances and equipment
and up to two circuits that include 240V appliances and
equipment.
NOTE: If you are unsure about the voltage requirement
for a device connected to a branch circuit, remove
that device before connecting the branch circuit to the
transfer switch.
lAfter identifying the branch circuits, select corresponding
transfer circuits based on amperage and wattage.
Branch circuits with 15A breakers can be paired to one
of six transfer circuits with 15A breakers. Branch circuits
with 20A breakers can be paired to one of two transfer
circuits with 20A breakers. Try to distribute loads with
similar wattage requirements equally on either side
of the switch. Refer to Wattage Capacity later in this
section.
NOTE: Do not pair circuits if the amperage rating
for branch circuit exceeds the rating for the transfer
circuit.
WATTAGE CAPACITY
Be certain that the generator can produce enough
start-up and running wattage to power all of the
items connected to the circuits you select. Wattage
information for most devices can be found directly on
the unit.
NOTICE
Do not overload the generator’s
capacity. Exceeding the generator’s wattage/
amperage capacity can damage the generator and/
or electrical devices connected to it.
Starting watts are typically higher than running watts
since some electrical motors draw more power when
rst started. Use the watt meters on the transfer switch
to monitor start-up surges and ensure the generator is
not overloaded.
For optimal performance the loads on the left side of
the transfer switch (circuits A-E) should be balanced
with the loads on the right side (circuits F-J) to within a
1000W. If necessary turn off the generator, ensure that
the main circuit breaker in the load center is in the OFF
position, and rebalance the load.
SAFETY
SAFETY INSTRUCTIONS FOR USING
PORTABLE GENERATORS
lPortable generators should only be used outside and
far away from vents, windows, and doors.
NOTICE
Install battery-powered carbon
monoxide detectors or plug-in carbon monoxide
detectors with battery back-up in living areas.
Using a generator indoors CAN KILL YOU IN MINUTES.
Generator exhaust contains carbon monoxide. This is a
poison you cannot see or smell.
DANGER
NEVER use inside a home
or garage, EVEN IF doors
and windows are open.
Only use OUTSIDE and far
away from windows, doors,
and vents.
lThis transfer switch should only be connected to a
generator with neutral oating.
lAlways turn the generator off before connecting or
disconnecting the power cord.
lMonitor the wattage meters and balance electrical
loads to avoid tripping the generator’s circuit breakers
or hindering the generator’s performance.
NOTICE
Do not connect branch circuits
with appliances or systems that exceed the switch
or the generator’s load capacity. Exceeding the load
capacity could damage the switch, the generator,
and any connected devices.
