Switch to utility power, Testing, Circuit breakers in load manager switch – Generac 1403-0 User Manual
Generac Portable Products Power Transfer System
6. At the Load Manager switches, move desired
circuit switches from LINE position to GEN
position (as shown in Figure 21).
The number of circuits that can be operated
simultaneously during a utility failure will depend on the
wattage capacity of your generator. Most portable
generators do not have the capacity to handle loads on
all Load Manager switch circuits at the same time.
Review the load management plan developed with the
installer (see Plan the Installation). It may be
necessary to selectively turn on and off certain loads
while using generator power so that necessary
appliances can be operated safely.
The watt meters provided on the Load Manager
monitor the current draw through each set of three
circuits (i.e.: circuits A, B, and C are monitored by
the lower left meter; circuits D, E, and F are
monitored by the lower right meter.) When switching
loads to the GEN position, watch the watt meter to
ensure that maximum current levels are not exceeded.
Switch To Utility Power
To revert from generator power to utility power after
utility power is restored:
1. At the Load Manager switches, place all
switches in LINE position, as shown in Figure 18.
2. Shut off the generator.
3. Disconnect the connecting cord set from the
generator and the connection box.
Following installation and periodically thereafter, test
the power transfer system as follows:
1. Ensure that all Load Manager switches are at
LINE position (see Figure 18).
2. Connect the connection cord set to the house
connector box (see Figure 19).
3. Connect the other end of the connection cord set
to the generator (see Figure 20).
4. Start the generator.
5. At one of the Load Manager switches, set the
A switch to the GEN position, as shown in
Figure 22. Verify that the load attached to the A
circuit is operating properly. Return A switch to
6. Repeat Step 5, above, for each remaining load
management circuit on both switches.
Circuit Breakers in Load Manager
Individual Load Manager switch circuits A through
F are each protected by a 15 Amp circuit breaker.
These breakers are labeled A, B, C, and so forth,
as seen in Figure 22, for example. If an electrical load
on one of these circuits exceeds 15 Amps, the Load
Manager switch circuit breaker will open.
To reset a Load Manager switch breaker:
1, Eliminate the overload condition.
2. Place the switch with the tripped circuit breaker in
the OFF or middle position.
3. Press in the circuit breaker button and observe that
the button remains in.
4. Place the switch that was in the OFF position back
to GEN (or LINE, if that is what is desired).
The load controlled by that Load Manager switch
circuit should now be operating properly.
If the circuit breaker does not reset, contact a licensed
electrician to repair the problem.
