The Greenlee 5708 and 5708-I GFCI and Circuit Testers are intended to verify the operation of a three-wire 120 volt ground fault circuit interrupter that has a standard (NEMA 5-15R) receptacle.

In addition to the GFCI testing capability, the 5708 and 5708-I also verify that the wiring is correct. They do not perform comprehensive diagnostic testing, but perform a simple check that detects most common wiring faults on three-wire circuits. Be aware that these tools will not detect two hot wires in a circuit, reversed grounded and grounding conductors, or multiple wiring faults. Also, they cannot indicate the quality of a ground.

In this manual, the term “GFCI” refers to a ground fault interrupter or a ground fault circuit interrupter.
The 5708 and 5708-I GFCI and Circuit Testers are used to verify the wiring and to check the operation of three-wire 120 volt ground fault circuit interrupters. The units connect a resistor between the hot lead and ground to create a small amount of leakage current. The GFCI is intended to trip when the leakage current is between 5 and 7 milliamps. When the GFCI trips, the circuit is opened and all the LEDs will shut off. If the GFCI does not trip within a specified time period, the GFCI is faulty and must be replaced.

• The 5708 creates the leakage current for 200 milliseconds, then shuts off for 4 seconds. This sequence is repeated continuously.
• The 5708-I creates the leakage current for the time duration indicated on the front of the unit, then shuts off. Total cycle time is approxi- mately 17 seconds, regardless of the selector setting. The sequence is repeated continuously.
