First, remove the control fuses in the
compartment. Connect the jumper
cable to the secondary disconnect plug
in the compartment and to the circuit
breaker. Insert the fuses. The charging
motor will automatically charge the stored
energy mechanism’s main closing springs.
Operation of the breaker control switch
on the front door of the compartment
will cause the circuit breaker to close. The
circuitry is arranged to cause the charging
motor to operate again and charge the
main closing spring. Operating the breaker
control switch on the front door will cause
the circuit breaker to open.
Pole unit parts are energized at full circuit
voltage when the circuit breaker is in the
connected position. Prior to moving the
circuit breaker into the connected position,
make sure that the main barrier assembly has
been properly fastened in place. Failure to
do so may cause equipment damage and/or
minor or moderate injury.

Refer to the metal-clad switchgear instruction
bulletin and drawings produced specifically
for the installed equipment for additional
information and cautions before attempting
to insert the circuit breaker into the metal-clad
switchgear equipment.
To insert the circuit breaker into the upper
compartment a lifting device must be used.
Refer to the Lifting Device instruction bulletin
for details on how to insert a circuit breaker
into the upper compartment.
NOTICE
Be sure that the racking crank arms at the
sides of the circuit breaker point in the
direction of the primary disconnecting devices
and the circuit breaker position indicator
displays breaker test/disconnected.
NOTICE
Each circuit breaker and circuit breaker
compartment is provided with interference
plates which are designed to ensure that no
circuit breaker with less than the required
voltage, continuous current, or interrupting
current rating is placed in the incorrect circuit
breaker compartment. If you attempt to insert
an improperly rated circuit breaker into the
circuit breaker compartment, these plates will
interfere with each other and deter further
insertion. The interference will occur before
the circuit breaker reaches the disconnected
position. Do not attempt to force the circuit
breaker past the compartment interference
plate or remove the interference plates from
either the compartment or the circuit breaker.
Remove the incorrectly rated circuit breaker
and insert a properly rated circuit breaker into
the circuit breaker compartment.
