Abstract
A mechanical interlock for interlocking two circuit breakers such that only one of the circuit breakers is ON at a given time. The interlock is also configured such that it permits both circuit breakers to be OFF at the same time. The interlock includes a pivoting rocker arm and a linkage assembly associated with each breaker, wherein the rocker arm and linkage assemblies cooperate to transfer motion between the tie bars of the circuit breakers.
