Patent ID: 7446271

Claim:
A system comprising: a breaker interlock device adapted to mechanically couple a handle of a first circuit breaker to a handle of a second circuit breaker, said breaker interlock device defining a first cavity adapted to receive said handle of said first circuit breaker, said breaker interlock device defining a second cavity adapted to receive said handle of said second circuit breaker, said breaker interlock device comprising: an upper portion partially defining said first cavity and said second cavity, said upper portion defining a first fastener receiving hole and a second fastener receiving hole; a first lower portion adapted to partially define said first cavity, said first lower portion defining a third fastener receiving hole, said first lower portion adapted to be releasably attachable to said upper portion via a first fastener, said first fastener adapted to fasten said upper portion to said first lower portion via said first fastener receiving hole and said third fastener receiving hole, when operatively installed, said breaker interlock device adapted to cause said first cavity to move transversely from a first location to a respective second location responsive to a movement of said handle of said first circuit breaker; and a second lower portion adapted to partially define said second cavity, said second lower portion defining a fourth fastener receiving hole, said second lower portion adapted to be releasably attachable to said upper portion via a second fastener, said second fastener adapted to fasten said upper portion to said second lower portion via said second fastener receiving hole and said fourth fastener receiving hole.
