CAUTION
1) Support Lock Pin, Support Hanger, and
Installation Template
Note:
The circuit breaker must be removed
from service when the support lock
pin is installed.
The lock pin and support hanger must be
installed to support the remote racking
device on the compartment door.
A template for placing the support hanger
in the correct location is available. Refer to
When installed, the racking device support
latch fastens onto the support lock pin, and
the slide assembly engages the support
hanger. The position of the racking device
enables the drive socket to engage the
circuit breaker racking shaft through the
access door to perform racking procedures.
To install the lock pin and support hanger,
follow directions accompanying the parts
order. For information on ordering the
support lock pin, support hanger, and
template, See
2) Testing and Inspection
a. Electrical Operation Check
To pretest the equipment, insert the
50’ cord from the box into the racking
device locking receptacle. Then insert
the motor control box power supply
cord into a 110VAC 15A receptacle, and
operate the box on the racking in and
racking out settings while the device is
not installed on the circuit breaker or
compartment door.
3) Remote Racking Device Inspection
a. Inspect the remote racking device
for proper lubrication, signs of wear,
or damage. If plugs and wiring are
damaged, return the equipment to
Powell for repair.
b. Inspect the switchgear compartment
to ensure that it is clean and clear of
debris that might interfere with circuit
breaker racking and travel within the
compartment.
