Abstract:
An interlock for an electrical panel having first and second power sources interconnected with respective first and second switches, wherein the first and second switches have respective first and second switch members movable in a substantially parallel relationship between an ON position and an OFF position, wherein the first and second switches are located adjacent each other on the panel and wherein a space is defined between the first and second switches, the interlock comprising:a support arrangement secured to the electrical panel within the space between the first and second switches, wherein the support arrangement includes a pair of spaced apart substantially planar support members wherein the support arrangement is configured so as to overlie an outwardly facing surface defined by the second switch so as to prevent removal of the second switch from the electrical panel; and an interlock member movably mounted to the support arrangement within the space between the planar support members, wherein the interlock member is movable between a first interlock position in which the interlock member enables movement of the first switch member between its ON and OFF positions while preventing movement of the second switch member to its ON position, and a second interlock position in which the interlock member enables movement of the second switch member between its ON and OFF positions while preventing movement of the first switch member to its ON position.
