Abstract
A defeatable interlock mechanism for an electrical equipment enclosure requiring a circuit breaker to be tripped before opening includes a support platform having an operator handle stem operably connected to the circuit breaker, an interlock slide plate slidably positioned along the support platform and having a keyhole-shaped slot for receiving a door interlock pin therein, and a lever operably connected to the interlock slide plate and configured to defeat the interlock mechanism when the door interlock pin is engaged with the slot. The lever is pivotally supported at a fulcrum point intermediate the ends of the lever and extends through an escutcheon to an exterior surface of the enclosure. Movement of the lever causes the interlock slide plate to disengage the door interlock pin and allow the unit door to open even while the circuit breaker is in the “on” position.
