  • Portable test apparatus for low current circuit breakers
    Patent number: 4998067
    Abstract: Portable testing apparatus for low current circuit breakers which enables short circuit and constant current tests to be conducted at the breaker panel. A first container includes a parallel array of resistive loads each under control of a corresponding relay. Low voltage control circuitry is provided in a second container and permits variation of the load appearing in series with the circuit breaker under test. The short circuit test can be performed at the first container which operates at the line voltage.
