Product FAQs

5 answers
Which load centers are compatible with the THQL1120GFTS circuit breaker?

This 1-inch plug-in breaker is designed for use in GE PowerMark Gold load centers, GE A-Series panelboards, AQ lighting panels, and ABB ReliaHome load centers.

Does the THQL1120GFTS require a pigtail neutral connection?

Yes, this breaker features a short pigtail neutral wire that must be connected to the neutral bus bar in the panel to properly power the ground fault circuitry.

What level of ground fault protection does the THQL1120GFTS provide?

It provides Class A 5mA ground fault protection for personnel, which is required by the NEC for wet or damp locations such as bathrooms, kitchens, and outdoor receptacles.

How does the self-test feature operate on this GFCI breaker?

The breaker automatically runs periodic internal diagnostics to ensure the ground fault circuitry is functioning properly. If a problem is detected, the breaker will trip and must be replaced.

Can the THQL1120GFTS replace older GE GFCI breakers?

Yes, this self-testing model supersedes legacy non-self-testing breakers like the THQL1120GF and serves as a direct replacement in compatible GE and ABB panels.
