MOVING THE CIRCUIT BREAKER FROM

THE CONNECTED TO THE DISCONNECTED

POSITION

DANGER

Hazard of fire, explosion, severe injury, death and property damage. Circuit breaker must be OFF before moving to or from the CONNECTED position.

TO MOVE THE CIRCUIT BREAKER TO THE DISCONNECTED POSITION:

1.Check to be sure that the On-Off Indicator reads OFF (Green). Push the manual trip lever in the direction of the arrow if necessary to open the circuit breaker. The interlock release lever cannot be raised unless the circuit breaker is OFF.

2.Grasp the handles on the breaker with both hands and, while lifting the interlock release lever with the left hand, pull the breaker out of the cell until the arrow on the front cover indicates the DISCONNECTED position has been reached (Fig. 23), then release the lever. Check to make sure the interlock release lever has returned to its original lowered position.

3.Optionally, disconnect the control circuit plug from the breaker (Fig. 24). The plug may remain connected if desired in order to perform tests on the control circuit with main power removed from the circuit breaker. If the plug is disconnected, it must be reconnected before the circuit breaker is returned to the CONNECTED position.
