Abstract:
1. An electrical safety monitor for monitoring electrical energy potentials of one or more electrical power input lines of an A.C. circuit, the electrical safety monitor including: one or more detector circuits, each of the detector circuits including: a discharge circuit electrically communicating with the one or more capacitors to cause a capacitor discharge at a predetermined capacitor voltage; a plurality of solid-state light-emitting devices disposed in a human-viewable arrangement, each light emitting device electrically communicating with a selected capacitor and producing a light output responsive to capacitor discharge of the corresponding capacitor; and the testing circuit arranged to provide a stored test current through each rectifier diode in the one or more detectors circuits providing verification of the electrical safety monitor integrity, wherein the testing circuit provides the stored test current in response to detecting a magnetic field in a vicinity of the electrical safety monitor; wherein test current is supplied via three connection inputs including: wherein upon one or more of the pluralities of rectifier diodes entering an open state, a corresponding one or more LEDs is not illuminated.
