Abstract
A two-part motor control center interlock arrangement has a handle support plate and interlock slide positioned on an interior of the control center door operating by insertion of a tapered pin on the door interior within a key-hole slot on the interlock slide. The elongated slot of the key-hole slot automatically compensates for any tolerance accumulation between a circuit breaker handle, an interlock operating handle and the control center access door.
