$12 off General Tools BF20 Circuit Breaker & GFCI Tester

The General Tools BF20 can perform four functions: Automatically identify the circuit breaker or fuse associated with any 110-Volt outlet without tripping the breaker or blowing the fuse. Identify five common wiring faults on a ground fault circuit interrupter (GFCI) outlet or conventional (non-GFCI) outlet. Check the functioning of a GFCI circuit. Safely—using non-contact voltage (NCV) detection—determine whether a line, cable or 110 Volt AC outlet is “hot” (energized).
