Abstract
An LCDI device comprising a first switching element coupled to a second switching element. A shield conductor coupled to the first switching element form a system that monitors output conductors of the device for faults. The second switching element is coupled to a relay that electrically connects input conductors of the device to output conductors of the device when the relay is energized by the second switching element. When a fault occurs, the first switching element generates a signal to the second switching element which de-energizes the relay causing said relay to electrically disconnect the input conductors from the output conductors.
