Test the Condition and Indication of GFI and Circuits with GFI and Circuit Tester
Instantly verify the correct wiring and check the operation of three-wire 120V ground fault circuit interrupters. GFI and Circuit Tester tests whether GFCI is acceptable at 5mA and 7mA. Indicates when GFCI starts tripping at 3mA due No line loss, too many in a series, etc. LED indicators signal correct wiring, open ground, open neutral, open hot, hot/ground reversed and hot/neutral reversed. 4-second interval between milliamp test impulses. 200-millisecond pulse
duration.
