Product FAQs
5 answersWhich load centers are compatible with the THQL1120AFP2?
This 1-inch plug-on breaker is designed exclusively for GE PowerMark Gold and ABB ReliaHome load centers. It is not interchangeable with other panel brands.
Does this breaker use a plug-on neutral or a pigtail neutral?
The THQL1120AFP2 features a standard pigtail neutral. The attached white wire must be routed and secured to the panel's neutral bus bar for the AFCI circuitry to operate correctly.
What does "Combination Arc Fault" mean for the THQL1120AFP2?
As a Combination AFCI (CAFCI), this breaker detects both parallel arcs (line-to-line, line-to-neutral, or line-to-ground) and series arcs (loose connections or broken wires in series with the load), providing comprehensive fire hazard mitigation.
Is there a difference between the THQL1120AFP2 and the THQL1120AF2?
Both catalog numbers represent the exact same 20A combination AFCI breaker with a pigtail neutral. The "P" in THQL1120AFP2 simply denotes retail blister packaging, while THQL1120AF2 indicates standard wholesale box packaging.
How should the AFCI function be tested after wiring is complete?
Energize the circuit and press the test button located on the face of the breaker. The breaker must trip immediately to confirm the internal arc fault detection is functioning properly.
