Patent ID: 7465892

Claim:
A system comprising: a breaker interlock sub-system adapted to mechanically resist switching a handle of a first circuit breaker from an OFF position to an ON position when a handle of a second circuit breaker is in an ON position, said first circuit breaker adjacent to said second circuit breaker, said first circuit breaker, said breaker interlock sub-system comprising: a faceplate assembly defining a first slidable plate receiving slot and a second slidable plate receiving slot; a first slidable plate releasably attachable to said faceplate assembly, said first slidable plate defining a first slot adapted to receive a first fastener, said first fastener adapted to attach said first slidable plate to said faceplate assembly, said first slidable plate, when in a first slidable position, via direct contact with said handle of said first circuit breaker, adapted to resist movement of said handle of said first circuit breaker from said OFF position to said ON position, said first slidable plate adapted, when in a second slidable position, to not resist movement of said handle of said first circuit breaker from said OFF position to said ON position; a second slidable plate releasably attachable to said faceplate assembly, said second slidable plate defining a second slot adapted to receive a second fastener, said second fastener adapted to attach said second slidable plate to said faceplate assembly, said second slidable plate, when in a primary slidable position, via direct contact with said handle of said second circuit breaker, adapted to resist movement of said handle of said second circuit breaker from an OFF position to said ON position, said second slidable plate adapted to, when in a secondary slidable position, not resist movement of said handle of said second circuit breaker from said OFF position to said ON position, said second slidable plate adapted to contact said first slidable plate such that said first slidable plate cannot be in said first slidable position when said second slidable plate is in said primary slidable position; and a breaker panel adapted to releasably house said first circuit breaker and said second circuit breaker, said breaker panel comprising a dead front, wherein said first slidable plate is adapted to be movable to a third slidable position relative to said first circuit breaker and said second slidable plate is adapted to be movable to a tertiary slidable position relative to said second circuit breaker, said dead front adapted to be removable with said first slidable plate in said third slidable position and said second slidable plate in said tertiary position, said breaker interlock sub-system adapted to function with said dead front removed.
