The CBA-1000 verifies the safe operation of 120VAC 15A and 20A circuit breakers. The handheld instrument plugs into any receptacle outlet to conduct a series of measurements like available voltage, wiring correctness, and voltage drop under load. It verifies if the breaker will safely respond to a short-circuit load on the branch circuit. During a breaker performance test, the instrument will detect series faults such as improper wire size, bad splices, and loose connections. All test data is recorded and can be viewed on the LCD or downloaded to a PC with the manufacturer’s software.
