The installer must provide an upstream branch circuit breaker. The input circuit breaker on the dis-
tribution box and the output circuit breaker on the rear of the power distribution box disconnect all
power between the main cabinet and the distribution box.
Models equipped with a manual bypass breaker pass bypass power directly to the bypass breaker
from the input terminal block. The input circuit breaker on the distribution box does not disconnect
power from the manual bypass breaker.
