ABSTRACT:
An alarm device for a circuit breaker box is provided that is especially designed for mounting on the face panel of conventional breaker boxes. The alarm device includes an audible signaling device and a switch box having a plurality of switches arranged in parallel electrical relationship for selectively coupling the audible signaling device to a source of operating power. The switch box includes a pair of spaced apart, apertured sidewalls for mounting the switches in side-by-side pairs of opposed switch members. A spring is interposed between each pair of switch members for urging the switch member pairs away from each other and into abutting relationship with electrical contacts carried by the sidewalls. In operation, the switch box is mounted between the vertical rows of breaker arm toggle switches of a conventional circuit breaker box. Individual alarm switch members are aligned in abutting contact with circuit breaker toggle switch members for shifting of the alarm switch members between open and closed positions in response to the shifting of the circuit breakers between normal and overload positions.
