ABSTRACT:
Indicator means located in a plug or connector indicates when at least one phase of an AC multi-phase voltage is absent. The indicator means can be any one of a variety of light sources and/or an audible generator. The light source can be, for example, an LED, an illuminating ring visible from any angle around the body of the plug or connector, etc. An opaque barrier can be used to totally or partially block the light from the light source when light from the light indicator may be objectionable such as during a stage lighting application. The indicator means for detecting the absence of at least one phase can be on a printed circuit board connected to receive power from the conductors in the plug or connector.
