Abstract
An assembly that prevents a circuit breaker from being racked into and out of a switchgear compartment unless the compartment door is closed completely. A coupling member protrudes through the door and has an exposed hexagonal-shaped end to receive a socket of a racking tool. When the door is closed, a recess of the coupling member receives a drive shaft that has a drive pin through it. The drive pin slides into a slot formed in the recess of the coupling member such that when the racking tool cranks the coupling member, the coupling member in turn cranks the drive shaft as the drive pin engages the slot in the coupling member. However, when the door is open, the coupling member is separated from the drive pin so rotating the coupling member does not turn the drive shaft. An optional padlock and deadbolt assembly provides added security against unauthorized access to the tool-receiving end of the coupling member.
