Abstract
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 including one or more capacitors corresponding to one or more electrical power input lines arranged to charge responsive to an electrical energy potential on the corresponding line and 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. A testing circuit generates a test current through the one or more detectors circuits providing verification of the electrical safety monitor integrity.
