Use this Klein Tools RT310 AFCI/GFCI outlet tester to detect the most common wiring faults in standard, AFCI and GFCI outlets. This device is capable of simulating arc fault conditions, ground fault conditions and can detect a dual-open wiring fault with simultaneous open neutral and open ground wires.

This unit is designed to test North American-style outlets in a 120 volt AC configuration via a three-prong outlet plug on a 10-inch flexible electrical cord. The tester requires three AAA batteries, which are included and installed in the unit.

This is a USED item but is in excellent condition.
