The motor control box (Figure 1, h) supplies
power and enables the selection of operating
modes for the electric racking device. The
motor control box has a 50 foot cord
(Figure 1, g) with a plug that is inserted into the
electric racking device twist lock power cord
receptacle (Figure 1, e). The length of the cord
enables the user to move to a remote location
from the circuit breaker during the racking in
or racking out procedures. The motor control
box power supply cord (Figure 1, f) plugs into a
110VAC outlet.

The electric racking device uses a hanger
bracket (Figure 1, b) to connect to the bottom
flange of the upper compartment. The drive
socket (Figure 1, c) engages the racking shaft
through the racking shaft access window
located on the switchgear between the upper
and lower doors (Figure 3). After the racking
device is installed, the motor adjustment knob
(Figure 1, d) can be turned to engage the drive
socket with the circuit breaker racking shaft.
When the racking device is connected to the
motor control box and energized, the drive
socket operates the circuit breaker racking
mechanism during the racking in or racking
out procedures.
