Troubleshooting guidelines
Condition
Push-to-test switch will not trip
circuit breaker.
LED turns ON and Blinks before
circuit breaker trips (indicated by
handle in center/trip position).
LED turns ON and Blinks
continuously.
Breaker trips upon being
energized (no LED indication).
Breaker trips upon being
energized.
Breaker trips upon being
energized.
Breaker trips when random loads
are applied to apparently
unprotected circuits.
GFCI self-test breaker functional checks
Unplug all items from the receptacles in the circuit. Reset the breaker by switching it OFF and then ON.
1. If the breaker trips, go to step 2.
If LED turns on or blinks continuously or LED turns on or blinks and the breaker handle moves to TRIP position ,
go to step 3.
If breaker remains in the "ON" position, go to step 4.
2. If handle moved to the TRIP position in step 1:
• First move handle to "OFF" position and TURN OFF POWER TO PANEL.
• Disconnect "LOAD POWER" and "LOAD NEUTRAL" wires from breaker.
• Restore power to panel and move breaker handle to the "ON" position.
If handle now remains in the "ON" position and trips when TEST BUTTON is depressed, GFCI breaker is operating
properly and there is a ground fault in the system (or) one of the poles of GFCI Self-Test are not connected/powered
from the Line side. Locate ground fault or connect/power-up both the poles, remedy and again perform installation and
functional checks.
3. If the LED turns on or blinks continuously or LED turns on or blinks and the breaker handle moves to TRIP position, then
replace the GFCI breaker. This LED is indicating that the GFCI breaker is no longer capable of providing protection.
4. Push TEST BUTTON. If the handle moves to the "TRIP" position and load is disconnected, the GFCI Breaker is operating
properly. To reset breaker, move handle to "OFF" and then to "ON" for normal operation. The issue is with one of the items
you unplugged or disconnected.

Potential cause
Circuit breaker is OFF/tripped.
Load center is not energized.
Load center neutral (pigtail) is not connected to
the neutral bus bar.
Circuit breaker is damaged.
This condition indicates that GFCI lost its
ground fault sensing capability due to a sensing
circuit failure.
This condition indicates that GFCI lost its
ground fault sensing capability due to a sensing
circuit failure.
Neutral (White) Wire is grounded on the Load
Side of the GFCI.
Excessive leakage to ground. Leakage currents
in excess of the trip level of the GFCI Self-Test 6
milliamp sensitivity between live parts of the
system wiring and ground, or between the live
side of wiring within equipment and its housing.
Swimming Pool Circuit — Connect only to
swimming pool equipment that has been
installed in accordance with the 1965 or later
National Electrical Code.
Multi-Wiring (Shared neutral wiring) — When
the GFCI neutral wire is common to two or more
separate circuits, the GFCI will trip when a load
current exists on any of the other sharing
circuits. This is an insidious problem and may
not be detected until someone plugs in a
receptacle or imposes some other load in some
remote part of the building.

Solution/action
Turn circuit breaker ON. Reset the
breaker by switching it OFF and
then ON.
Check to be sure load center
is energized.
Check neutral (pigtail) connection.
Replace circuit breaker.
Replace circuit breaker.
Replace circuit breaker.
The neutral ground must be cleared
for proper operation of the GFCI.
The leakage to ground must be
cleared for proper operation of
the GFCI.
Some shared neutral circuits can
be successfully protected by using
a 2 pole GFCI breaker. Other forms
of shared neutrals can only be
corrected by some rewiring. This
GFCI must have its own private
circuit.
