RACKING MECHANISM
Refer to Figure 3, page 8. With the circuit breaker resting
on the cubicle rail, the following sequence should be used
to rack the circuit breaker into the cubicle.
1. Push trip bar in, open racking window and insert rack-
ing crank.
NOTE Racking window cannot be opened unless
manual
trip bar is pressed in. While the trip bar
is pressed in, the circuit breaker is in the TRIP-
FREE position and cannot be closed.
2. With the racking crank, rotate the racking screw (105)
counterclockwise until the racking shaft is in the dis-
connected position. The clevis can now engage the
racking pins in the cubicle. The circuit breaker should
now be pushed along the rail into the DISCON-
NECTED position. Double check that the racking clev-
is does engage the pins in the cubicle.
3. Clockwise rotation of the racking screw will rack the
breaker into the TEST position. At the TEST position,
the racking window can be closed, allowing the trip
bar to reset and the circuit breaker can be operated.
Further racking will place the circuit breaker between
the test and fully connected positions. Between posi-
tions, the interlock bar will not engage the position
holes of the cubicle. The breaker will be held TRIP-
FREE and cannot be closed.
