Abstract
Circuitry is utilized to interconnect loads to the power distribution system and only conducts current when voltage conditions from the system are appropriate. Therefore, the load is deenergized whenever reversed connections are made to the power distribution system, or whenever an open circuit exists in any line thereof. Latching means can be included in the circuitry to continually energize the load when an open circuit develops in either nongrounded or hot line of the power distribution system after the load has been initially energized therefrom. Furthermore, the effect of the latching means is externally controlled through a switching means so that remote circuit conditions can be synchronized therewith. When an indicating means is incorporated as the load, the circuitry functions as a detector and when the circuitry is utilized with a circuit breaker to deenergize the load, ground fault protection can be incorporated therewith.
