5.6 Circuit Breaker Replacement Procedures

These procedures are only for RA Series service entrance transfer switches.

WARNING

The transfer switch presents a shock hazard that can cause severe personal injury or death.

Before beginning installation, remove all sources of AC power. If a generator provides

emergency power, move the generator operation selector switch to Stop, disconnect AC line

power, disconnect the battery charger from its AC power source, and disconnect the starting

battery (negative [-] lead first).

1. RA 100A/200A transfer switch models only:

a. Remove all sources of power from the transfer switch in the following order.

i. Move the operation selector switch on the generator set to Stop (Off).

CAUTION

Always disconnect a battery charger from its AC source before disconnecting the

battery cables. Otherwise, disconnecting the cables can result in voltage spikes

high enough to damage the DC control circuits.

ii. If there is an external battery charger, disconnect the battery charger from its AC power

source.
