ABSTRACT:
Transient voltage surge suppression (TVSS) meter adapter status indication perceptible by a nearby observer. When TVSS over-voltage protective means is on-line, a visible and/or audible signal is generated within the meter adapter housing and is transmitted to the exterior. Light emitted by an indicating lamp connected in series with the over-voltage protective element is transmitted to the exterior by means of a translucent rod to which the lamp is juxtaposed extending through the meter adapter housing wall and terminating just outside. Sound emitted by a buzzer similarly located is transmitted through the housing wall upon demand of an an observer outside, who actuates a normally open switch in series with the buzzer by juxtaposing a small magnet against the housing wall.
