Claims5
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 is adapted for said first circuit breaker to be adjacent to said second circuit breaker, said breaker interlock device is adapted for said first circuit breaker and said second circuit breaker to be in a side-by-side orientation, said breaker interlock device comprising:
- a first ear adapted to clipably attach said breaker interlock device to at least said first circuit breaker;
- a second ear adapted to clipably attach said breaker interlock device to at least said second circuit breaker;
- a clip adapted to snapably attach said breaker interlock device to said first circuit breaker and/or said second circuit breaker;
- and
- a boomerang-shaped latch adapted to contact said handle of said first circuit breaker and said handle of said second circuit breaker, said boomerang-shaped latch adapted to resist motion of said handle of said first circuit breaker from an OFF first position to an ON second position unless said handle of said second circuit breaker is in an OFF position.
