Abstract of the Disclosure An apparatus and method for testing voltage arresters and current shunting circuits within a telephone circuit protector are described. A typical protector tested by the apparatus and method includes two voltage arresters and two current limiting circuits. One set of a voltage arrester and a current limiting circuit are tested for voltage breakdown, continuity and ground faults by actuation of a single test operating switch. The other voltage arrester and current limiting circuit are then selected and tested by a single actuation of the test operating switch. Breakdown voltage, continuity, ground fault and low battery visual indicators are provided.
