Examine the circuit breaker
compartment to see that it is clean and
clear of debris that might interfere with
circuit breaker travel.
b. Racking the Circuit Breaker into the
Circuit Breaker Compartment
The described racking procedures
apply only for indoor type and non arc
resistant constructions. For all other
constructions, refer to the appropriate
instructions or instruction bulletin(s) for
the applicable racking procedures.
Racking a circuit breaker into the
circuit breaker compartment may
be accomplished by several similar
methods.
The Closed Door Racking circuit breaker
(CDR) may be racked manually or
electrically using the optional Power
Racking device. Power racking enables
the user to rack the circuit breaker
with a motor-driven mechanism with
an electric control. This enables the
user to perform the racking function
without being located in front of the
circuit breaker compartment. The
power racking device mounts onto
the compartment door. Refer to the
instruction bulletin provided with the
Power Racking Device
for the proper
operation and use.
Before inserting a circuit breaker into the
circuit breaker compartment, be sure that
the indicator flag on the front cover of the
circuit breaker displays “TEST/ DISCONNECT”.
CAUTION

Before attempting to rack a circuit breaker
in or out of a circuit breaker compartment
equipped with a key interlock, make sure
