Product FAQs
5 answersWhat panelboards are compatible with the THQB2125GFT circuit breaker?
This bolt-on breaker is designed for use in GE A-Series panelboards, GE AQ lighting panels, and ReliaGear RQ panelboards. It is not compatible with standard Powermark Gold load centers, which require plug-on THQL breakers.
How is the neutral connected on the THQB2125GFT GFCI breaker?
This breaker features a pigtail neutral wire that must be connected directly to the panel neutral bus. This connection is required to power the internal ground fault circuitry, even if the 240V load does not require a neutral.
What is the ground fault trip threshold for this breaker?
The THQB2125GFT is a Class A GFCI device designed for personnel protection. It will trip when it detects a ground fault current imbalance of 4 to 6 milliamps.
Can I use the THQB2125GFT to replace a THQL2125GFT?
No. While both are 25A, 2-pole GFCI breakers, the THQB2125GFT has a bolt-on connection for commercial panels. The THQL2125GFT has a plug-on connection for residential load centers. They are not interchangeable.
What does the LIG trip function code mean on this breaker?
The LIG code indicates the breaker provides Long-Time thermal overload protection, Instantaneous magnetic short-circuit protection, and Ground Fault protection.
