Product FAQs

6 answers
What load centers are compatible with the THQL1120PGFT breaker?

This breaker is designed for use in GE PowerMark Gold and ABB ReliaGear load centers equipped with a Plug-On Neutral (PON) design. It will not install correctly in older panels that lack a plug-on neutral bus.

Does the THQL1120PGFT require a pigtail wire for the neutral connection?

No. The P in the catalog number indicates it is a Plug-On Neutral breaker. It connects directly to the neutral bar in a compatible plug-on neutral load center, eliminating the need to route and terminate a separate pigtail wire.

Can I use this breaker in a standard GE Q-Line panel without a plug-on neutral?

No. If your GE load center does not have a plug-on neutral bus, you must use the pigtail version of this breaker, catalog number THQL1120GFT, instead of the PGFT model.

What level of ground fault protection does this breaker provide?

The THQL1120PGFT provides Class A ground fault protection, tripping when a ground fault of 5mA is detected. It also includes a built-in self-test feature that automatically verifies the GFCI circuitry is functioning properly.

Does the THQL1120PGFT provide arc fault (AFCI) protection?

No, this model provides ground fault (GFCI) protection only. For combination arc fault and ground fault protection in a plug-on neutral panel, a dual-function breaker like the THQL1120PDF is required.

Why might my THQL1120PGFT breaker arrive with ABB branding instead of GE?

ABB acquired GE Industrial Solutions in 2018. Depending on the manufacturing date, this breaker may be branded as either GE or ABB. Both versions are identical in form, fit, and function, and are fully interchangeable under manufacturer specifications.
