Abstract:
A system for monitoring and providing a safety disconnect for a plurality of light circuits, comprising:a monitor device electrically coupled to a light circuit service panel, said monitor device comprising: a switching means complementary to an existing disconnect means operable to independently disconnect a light circuit from a power source; input means for collecting real-time data, said input means including: means for detecting unequal current levels in said plurality of light circuits; means for continuous surveillance of ground wire continuity for the light circuit; means for continuous sensing of the current level in a light circuit; means for continuous sensing of the voltage level in the light circuit; and a processor coupled to said input means, said processor operable to perform the steps of: analyzing said current level in each light circuit in real time by comparing the current level with known parameters; analyzing said voltage level in each circuit in real time by comparing the voltage level with known parameters; computing power usage in each circuit and analyzing said power usage by comparison with known parameters; determining if disconnect conditions exist in each circuit; and disconnecting the circuit from a power source if said disconnect conditions exist.
