Product FAQs
4 answersWhich load centers and panelboards are compatible with the THQL2145GFT2?
This breaker is designed for use in GE PowerMark Gold load centers, GE A-Series panelboards, and ABB ReliaHome load centers that accept 1-inch plug-on Q-Line breakers.
What level of ground fault protection does the THQL2145GFT2 provide?
It provides Class A ground fault protection, which trips at a 5mA threshold to protect personnel from electrical shock. It also features automatic self-testing to ensure the GFCI circuitry remains active and compliant with current electrical codes.
How is the neutral connection made for this GFCI breaker?
This breaker features a pigtail neutral connection. The coiled white pigtail wire must be connected directly to the panel neutral bus bar for the ground fault detection to function properly.
Is the THQL2145GFT2 manufactured by GE or ABB?
ABB acquired GE Industrial Solutions, so this breaker may be branded as either ABB or General Electric. Both brands represent the exact same Q-Line breaker and are fully interchangeable.
