Limited space circuit breaker mechanical interlock apparatus

A circuit breaker mechanical interlock apparatus comprising

• a housing having a back wall and a pair of side walls depending from the back wall, the back wall and the side walls defining a receptacle for receiving a plurality of switch-type circuit breakers, each of the switch-type circuit breakers having a manually operable switch that is movable between at least two positions;
• an interlock slide mounted on the housing and movable between a first position wherein the interlock slide overlies a first circuit breaker of the switch-type circuit breakers and thereby prevents manual operation of a first switch corresponding to the first circuit breaker and a second position wherein the interlock slide overlies a second circuit breaker of the switch-type circuit breakers and thereby prevents manual operation of a second switch corresponding to the second circuit breaker;
• and
• a faceplate secured to the housing;
• wherein the interlock slide is retained between the housing and the faceplate.

An interlock slide for a circuit breaker mechanical interlock apparatus having a housing that defines a receptacle for receiving a plurality of manually operable switch-type circuit breakers, the interlock slide comprising

• a locking bar that overlies a first circuit breaker of the switch-type circuit breakers and thereby prevents manual operation of a first switch corresponding to the first circuit breaker when the interlock slide is in a first position;
• means supporting the interlock slide on the housing such that the interlock slide is movable from the first position to a second position wherein the locking bar overlies a second circuit breaker of the switch-type circuit breakers that is parallel to and linearly adjacent to the first circuit breaker and thereby prevents manual operation of the second circuit breaker;
• and
• a faceplate secured to the housing;
• wherein the interlock slide is retained between the housing and the faceplate.

A circuit breaker mechanical interlock apparatus for preventing more than one power source from energizing an electrical system at any given time, the apparatus comprising

• a housing defining a receptacle for receiving a plurality of switch-type circuit breakers, each of the circuit breakers having a manually operable switch that is movable between at least two positions for actuating one of a plurality of power sources electrically connected to a first circuit breaker of the switch-type circuit breakers and to the electrical system;
• and
• at least one interlock slide movably mounted on the housing adjacent the receptacle and opposite the switches of the circuit breakers, each interlock slide being movable relative to the circuit breakers to a first position wherein the interlock slide overlies the first circuit breaker and thereby prevents movement of a first switch corresponding to the first circuit breaker and to a second position wherein the interlock slide overlies a second circuit breaker of the switch-type circuit breakers and thereby prevents movement of a second switch corresponding to the second circuit breaker;
• and
• a faceplate secured to the housing;
• wherein each interlock slide is retained between the housing and the faceplate.
