CONTROLS AND FEATURES

Select ARL Circuits - Generator

Select the circuits to be powered by the generator. Remove the

selected breakers from the main panel.

If the removed breakers are of an accepting type, install them

in the ARL. If not,discard them and buy suitable breakers of the

correct ampacity.

Extend the branch circuit conductors from the main panel into

the ARL by using suitable gauge and color of approved building

wire and appropriate wire connectors.

The ARL is UL listed for several 1-inch interchangeable breakers

(see label on the inside cover of the ARL) or, page 10, of the

Circuit Breakers section.

Install only circuit breakers that are compatible with ARL branch

circuit.

Pull wire to new circuit breakers in ARL branch circuit from

circuit breaker in Load center.

Use Copper Wire only, 75°C Minimum

Connect each branch circuit conductor (wire) to its appropriate

branch circuit breaker from the Load center.

Repeat for each of the selected circuits.

The branch conductors must be connected to the same

ampacity breakers as they were when they were in the Load

center.

Make certain that the total amp capacity of the selected circuits

does not exceed the maximum capacity of the generator.

Balance the load on the ARL by dividing the branch circuit

breakers evenly between the two sides as shown in Figure 1.
