Condition
Push-to-test switch will
not trip circuit breaker
LED turns ON or Blinks
before circuit breaker trips
(indicated by handle in
center/trip position).
LED turns ON or Blinks
continuously.
Breaker trips upon being
energized.

Breaker trips when random
loads are applied to

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.
One of the poles of the circuit breaker is not powered
or is somehow disconnected from the Line side.
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 or trip 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.
One of the poles is not powered or is disconnected
from the GFCI Self-Test's Line side.
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.
Fix connection issue.
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.
Both the poles must be connected and be
powered simultaneously.
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.
