Ground fault circuit interrupter with self-test
feature (GFCI)
Type THQ/THHQ 15A-30A, 2 pole
Installer instructions
Install the ground fault circuit interrupter with
Self-test (GFCI) using the following procedure:
1. Ensure power to the panel is “OFF” and read all warnings
on the adjacent page before installation of the GFCI
commences.
2. Move handle of breaker to “OFF” position.
3. Connect the coiled white wire (pigtail) of the GFCI to any
terminal on the neutral bar in the panel.
4. System Voltage – Both sides of the 120/240 Vac supply
must be present, otherwise the GFCI will trip.
5. On 120/240 Vac load applications connect the WHITE
insulated neutral load wire of the circuit to be protected
to the GFCI’s terminal lug marked LOAD NEUTRAL. On 240
Vac load applications where the neutral is not required,
no connection is made to the GFCI’s terminal lug marked
LOAD NEUTRAL.
6. Connect the BLACK insulated load wire of the circuit to be
protected to the GFCI’s terminal lug marked “LOAD
POWER”.
7. Connect the RED insulated load wire of the circuit to be
protected to the remaining GFCI’s terminal lug. Check to
assure the GFCI is still in “OFF” position and all wires are
properly connected.
8. Install the wired GFCI into the panel.
9. Restore power to the panel.
10. Follow Test Procedures as indicated at the bottom of
next section.

WARNING:
Failure to follow these instructions could
result in death, personal injury, or property damage.
See Troubleshooting Guidelines on the second page of
this instruction sheet. This equipment must be installed
and serviced only by a qualified electrician.
WARNING:
Turn off power to main breaker before
beginning installation. Failure to do so will risk electrical
shock and possible death, personal injury, or property
damage.
WARNING:
Do not reverse-feed or back-wire. Do not
subject circuit breaker to megger, high-voltage, or
high-pot tests. Remove the circuit breaker before
high-pot testing the circuit or the system.
CAUTION:
The Ground Fault Circuit Interrupter (GFCI)
must be supplied with power from the load center in
order for the push to test to function properly. If the
power is on and push to test fails to trip or the LED turns
on or blinks (indicating the self-test feature has detected
an issue), the GFCI may not be able to detect leakage
current. The circuit breaker is defective and should be
replaced.
NOTE:
These instructions do not cover all details or
variations in equipment nor do they provide for every
possible contingency that may be met in connection with
installation, operation, or maintenance. Should further
information be desired or should particular problems
arise that are not covered sufficiently for the purchaser’s
purposes, the matter should be referred to the ABB
Company. See contact information on next page.
Test procedures (GFCI should be
tested regularly, at least once per
month.)
1. With handle B in “ON” position,
press “PUSH TO TEST” button A up
or down.
2. Handle B should move to “TRIP”
position, indicating that GFCI has
opened the circuit.
3. To restore power, move handle B to
“OFF” and then “ON”.
IMPORTANT:
If handle B does not move to “TRIP” position
when “TEST” button is pressed, the GFCI’s protection is
not complete. Replace breaker immediately.
PON panel neutral connection in PowerMark Pro only
IMPORTANT:
Q-Line Plug-on Neutral (PON) eMCBs do not
have a pigtail and can only be installed in PowerMark Pro
Load Centers. The PON eMCB neutral stab will automatically
connect to the panel’s integrated neutral bar during normal
product installation. Please refer to the diagrams below.
