Product FAQs
6 answersWhich electrical panels are compatible with the THQL2150GF1?
This plug-on breaker is designed for use in GE PowerMark Gold load centers, GE A-Series panelboards, and ABB ReliaHome load centers.
What level of ground fault protection does the THQL2150GF1 offer?
It provides Class A 5mA ground fault protection, which is designed to protect personnel from electrical shock in wet or damp locations.
Is the THQL2150GF1 interchangeable with the THQL2150GFT?
Yes. The THQL2150GFT is the newer, direct replacement for the legacy THQL2150GF1 and THQL2150GF models. The T suffix designates the addition of an automatic self-test feature required by updated UL standards, but they share the same physical dimensions and panel compatibility.
How is the neutral connection handled on this GFCI breaker?
The THQL2150GF1 features a pigtail neutral wire that must be connected directly to the neutral bus bar in your load center to ensure the ground fault circuitry functions correctly.
What wire sizes do the box lugs on this 50A breaker accept?
The terminals are rated to accept 8 AWG to 3 AWG copper or aluminum wiring.
Is this breaker suitable for systems with high fault currents?
The THQL2150GF1 has a maximum interrupting rating of 10kAIC at 120/240VAC. It should not be installed in systems that require a higher short-circuit current rating.
