Description
Designed to simplify panel wiring, the THQL1120PAF2 is a 1-pole, 20A combination arc-fault circuit interrupter from GE's Q-Line series. It utilizes a plug-on neutral connection that eliminates the need for a standard pigtail wire, speeding up installation. This breaker mounts into compatible GE PowerMark Gold and ABB ReliaHome load centers equipped with plug-on neutral bars. Providing 10kAIC at 120/240V, it detects both parallel and series arcing to protect residential circuits.Specifications

Product FAQs
8 answersDoes the THQL1120PAF2 require a neutral pigtail wire?
No. This breaker features a plug-on neutral (PON) clip that mounts directly to the neutral bus bar in compatible panels. This design eliminates the need to route and terminate a separate pigtail wire in the panel gutter.
Will this breaker fit in any GE Q-Line load center?
It only fits GE PowerMark Gold and ABB ReliaHome load centers specifically equipped with a plug-on neutral bus. It cannot be installed in legacy panels that lack PON architecture.
What differentiates the THQL1120PAF2 from the THQL1120AF2?
The P in THQL1120PAF2 indicates a plug-on neutral design for PON-equipped load centers. The THQL1120AF2 lacks this clip and instead relies on a standard neutral pigtail wire, making it necessary for older, non-PON panels.
Does this unit provide combination arc-fault protection?
Yes. It is a Combination Arc-Fault Circuit Interrupter (CAFCI), meaning it detects both series and parallel arcing conditions to meet NEC 210.12 requirements for 120V branch circuits in dwelling units.
Where do I connect the branch circuit neutral on this breaker?
The load neutral wire from the branch circuit lands directly on the breaker's dedicated load neutral terminal. The breaker then completes the neutral return path to the panel internally through its PON clip.
Is this 20A AFCI rated for 100 percent continuous duty?
No. Like standard miniature circuit breakers, it is rated for 80 percent continuous load. Continuous loads operating for three hours or more should not exceed 16 amps on this 20-amp device.
Can I use the THQL1120PAF2 in a system requiring more than 10 kAIC?
This specific breaker is rated for a maximum of 10 kAIC at 120/240V. If the electrical service requires a higher interrupting capacity, you must specify a different breaker series, such as the THHQL1120PAF2, which offers a 22 kAIC rating.
Can this replace a standard THQL1120 breaker during a panel upgrade?
Yes. For 120V branch circuits requiring arc-fault protection upgrades, it replaces standard 1-pole 20A THQL breakers, provided the existing load center has a compatible plug-on neutral bus.
