GFCI Test
XWWarning
To avoid electrical shock, do not touch any exposed
metalwork during the test.
This test will switch off the power to the circuit.
To test a GFCI receptacle, do the following:
1. Insert the Tester probes into the GFCI receptacle under test.
2. Connect probes to the phase (hot) and ground (PE-protective earth)
of the GFCI receptacle.
3. Press for 1 second. The DC+ and DC- LEDs will alternately
switch on and off and, if activated, the beeper will sound indicating
that a test is in progress. The test may last up to 7 seconds.
4. Keep the probes connected while the LEDs are switching on and off.
If the GFCI trips, power to the circuit will be interrupted and the Tester
will stop indicating voltage. If the GFCI does not trip after
approximately 7 seconds, the GFCI test stops, indicated by no
switching of the DC+ and DC- LEDs but the tester will continue to
indicate the presence of voltage.
When testing and verifying GFCI circuits or components, do the following:
• Consult the GFCI manufacturer’s installation instructions to determine
that the GFCI is installed in accordance with its specifications.
• Check for correct wiring of receptacles and all remotely-connected
receptacles on branch circuits.
• Operate the pushbutton on the GFCI receptacle installed in the
circuit. The GFCI must trip. If it does not, the GFCI receptacle is not
operating properly. DO NOT use the circuit. Consult an electrician or
properly certified personnel.
If the GFCI does trip, retest the receptacle as explained above.
If the Tester fails to trip the GFCI, consider either of the following:
• The GFCI is fully functional but a wiring problem exists within the
installation or receptacle.
• The GFCI is faulty and the installation wiring is correct.
Consult an electrician to check the wiring and GFCI.
Note
• After a GFCI test, further GFCI tests will be inhibited for 0.5
seconds.
• It is not possible to switch the beeper off during a GFCI test.
XWWarning
To avoid possible electric shock or personal injury, follow
these guidelines:
• When testing GFCIs installed in 2-wire systems,
(systems where no ground wire is available at the
receptacle) the Tester may give a false indication that
the GFCI is not functioning properly. If this occurs,
recheck the operation of the GFCI using the test and
reset button.
