Abstract:
A method of preventing two circuit breakers from operating in the same electrical circuit, with each circuit breaker having a crossbar and contact assembly, the method comprising the steps of:providing a first operator rod configured to engage the crossbar and contact assembly of one circuit breaker; providing a second operator rod configured to engage the crossbar and contact assembly of the other circuit breaker; providing an interlock yoke having two ends, with a notch proximate each end of the yoke; mounting the yoke a spaced distance from the two circuit breakers; pivoting the yoke a distance between the two circuit breakers; and aligning each notch with one of the first and second operator rods, wherein, when one operator rod is moved by the crossbar and contact assembly of one circuit breaker, that operator rod pivots the yoke causing the other operator rod to block the operation of the other circuit breaker.
