Abstract
An apparatus is for visual indication of an energized state of electrical conductors. The apparatus includes two electrodes structured to capacitively couple to two energized electrical conductors, respectively, in order to harvest an electric field. A rectifier is powered from one or both of the two electrodes. An illuminated indicator or a non-illuminated indicator is powered from the rectifier.
