SYSTEM OPERATION
Load Management
The number of circuits that can be operated
simultaneously during a utility failure will depend on the
wattage capacity of your generator. Most optional
standby system generators do not have the
capacity to handle loads on all transfer switch
circuits at the same time.
Review the load management plan developed with the
installer. It may be necessary to selectively turn on and
off certain loads while using generator power so that
necessary appliances can be operated.
To transfer from utility power to generator power:
1. Align female socket of connecting cord set with
inlet box receptacle’s mating male prongs, as
shown in Figure 11. Push cord set connector in and
twist clockwise to lock.
2. Align male prongs on other end of cord set with
mating female terminals of generator’s 240V
receptacle, as shown in Figure 12. Push in
connector and twist clockwise to lock.
3. Ensure generator is outdoors as described in
generator operator’s manual.
4. Start generator following instructions given in the
generator operator’s manual.
5. Turn OFF breaker labeled “UTILITY SUPPLY” in
transfer switch.
6. Turn OFF all branch circuit breakers in transfer switch.
7. Slide mechanical interlock in transfer switch and turn
“GENERATOR SUPPLY” breaker to ON position.
8. Turn ON branch circuit breakers one at a time
following your load management plan developed
with installer. DO NOT overload generator as
described in generator operator’s manual.
To transfer from generator power back to utility
power:
1. Turn OFF breaker labeled “GENERATOR
SUPPLY” in transfer switch.
2. Turn OFF all branch circuit breakers in transfer switch.
3. Slide mechanical interlock in transfer switch and
turn “UTILITY SUPPLY” breaker to ON position.
4. Turn ON branch circuit breakers one at a time.
5. Shut off generator following instructions given in
generator operator’s manual.
6. Disconnect connecting cord set from generator
and inlet box.
IMPORTANT: ALWAYS unplug cord when not in use
and store INDOORS.
