ABSTRACT:
A contactor interlock assembly operable with a racking arrangement for engaging and disengaging a contactor unit with a bus bar arrangement disposed relative to a contactor unit support structure. The contactor interlock assembly includes an arrangement for disabling the racking arrangement when the contactor unit is "ON." A cable connects the racking arrangement to a lever bracket supported by the support structure which is operated by a lever on the contractor unit. The lever operates the lever bracket which causes the cable to disable the racking arrangement. The interlock assembly may also include a second lever bracket associated with a second contactor unit. The second lever bracket is coupled to the first lever bracket by a cable such that the contactor units are also interlocked, such that the operation of one contactor unit is made dependent upon the operation of the other contactor unit.
