6. At the Load Manager™ switches, move desired

circuit switches from “LINE” position to “GEN”

position (as shown in Figure 21).

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 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

“LINE” position.

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.
