Product FAQs
7 answersWhich load centers are compatible with the THQL2140GFT2 breaker?
This breaker is designed for use in GE PowerMark Gold and ABB ReliaHome load centers that accept Q-Line plug-on breakers.
Can I use this THQL breaker in place of a THQP breaker?
No. THQL breakers are full-size, measuring 1 inch per pole, while THQP breakers are half-inch slimline breakers. They are not directly interchangeable. You must verify that your panel accepts full-size THQL breakers.
How is the neutral connected on the THQL2140GFT2?
This breaker features a pigtail neutral connection. The coiled white wire must be connected directly to the neutral bus bar in the panel for the ground fault protection to function correctly.
What is the ground fault trip sensitivity for this breaker?
The THQL2140GFT2 provides Class A ground fault protection, meaning it is designed to trip when it detects a ground fault current of 5mA. This provides personnel protection for applications like spas, pools, and bathrooms.
Does this GFCI breaker include a self-test feature?
Yes, it includes an integrated self-test function that automatically runs periodic diagnostic testing on the internal circuitry to ensure the ground fault protection is working properly.
Why is this breaker listed as both ABB and General Electric?
ABB acquired GE Industrial Solutions. As a result, Q-Line breakers like the THQL2140GFT2 may be branded as either ABB or General Electric, but they are the exact same product and are fully interchangeable.
Does the THQL2140GFT2 replace older GE models?
Yes, the THQL2140GFT2 serves as a direct, upgraded replacement for the older THQL2140GFT model.
