Description
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.

Important Safety Information
Electric shock hazard:
• Do not apply more than the rated voltage between any two input
terminals, or between any input terminal and earth ground.
• Do not contact the test lead tips or any uninsulated portion of the
accessory.
Failure to observe these warnings can result in severe injury or
death.
Electric shock hazard:
• Do not use the unit if it is wet or damaged.
• Inspect the test leads or accessory before use. The item(s) must
be clean and dry, and the insulation must be in good condition.
Failure to observe these warnings can result in severe injury or
death.

Introduction
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.

1. To help prevent false readings, unplug any appliances or equipment
on the circuit under test.
2. Set the selector to 0 mA and plug the unit into the GFCI’s receptacle
(NEMA 5-15R type only).
3. Compare the LEDs illuminated on the 5708 or 5708-I to the
diagram on the face of the unit.
Note: If the LEDs indicate anything other than “Correct Wiring”,
have the wiring corrected by a qualified electrician.
4. Press the GFCI’s built-in reset button, then press its test button.
5. After resetting the GFCI, move the selector to the next higher setting.
The red test LED will turn on to indicate that testing is in progress, and
will turn off when the test is finished or when the GFCI trips.
6. Wait for the red LED to turn on and off. Observe the yellow LEDs on
the unit to determine if the GFCI has tripped. If not, move the
selector to the next higher setting. Repeat this process until the
GFCI trips or until the highest setting is reached. The setting at
which the GFCI trips is the Leakage Current Trip Point. See the
Settings Table.
Electric shock hazard:
•Contact with live circuits can result in
severe injury or death.
•The 5708 and 5708-I cannot properly test
two-wire circuits.

7. Plug the unit into every receptacle on the circuit, including all
remotely connected receptacles on all branches that are in series
with the GFCI. Using the procedure detailed above, verify that every
receptacle is properly wired to and protected by the GFCI.
Operation (cont’d)
Settings Table
Leakage Current Trip Point GFCI Condition
Trips at 3 mA GFCI is oversensitive.
Trips at 5 mA GFCI is acceptable.
Trips at 6 mA (5708-I only) GFCI is acceptable.
Trips at 7 mA GFCI is acceptable.
Trips at 10 mA GFCI is faulty. REPLACE THE GFCI.
Trips at 30 mA (5708 only) GFCI is faulty. REPLACE THE GFCI.
Does not trip. GFCI is faulty, or it was wired incorrectly
when it was installed. Have a qualified
electrician verify that it was installed
and wired according to the GFCI
manufacturer’s instructions. If the GFCI
still does not trip, REPLACE THE GFCI.
