Product FAQs
7 answersWhat panelboards accept the THHQB2115GFT circuit breaker?
This bolt-on breaker is designed specifically for GE A-Series and ABB ReliaGear RQ panelboards. It is not compatible with residential load centers that require plug-in Q-Line breakers.
Can I install a THHQB breaker in a panel that currently uses THQB breakers?
Yes, THHQB breakers share the exact same physical dimensions and bolt-on mounting configuration as standard THQB breakers. The THHQB series simply provides a higher interrupting rating for systems requiring 22kAIC.
What does the GFT suffix indicate on this GE breaker?
The GFT suffix designates that the breaker includes an internal self-test feature for its ground fault circuitry. This automatic testing ensures the GFCI components are functioning correctly to meet updated UL standards.
How is the neutral connection made for this GFCI breaker?
The THHQB2115GFT includes a factory-installed pigtail neutral wire. This coiled white wire must be routed and terminated directly to the neutral bus bar in the panelboard for the ground fault sensing to operate.
Does the THHQB2115GFT replace the older THHQB2115GF?
Yes, it is the direct replacement. The T at the end of the catalog number indicates the addition of an automatic self-test function, which was introduced to comply with updated UL 943 standards for GFCI devices.
Is the THHQB2115GFT interchangeable with a THQL2115GFT?
No. Although they share the same electrical ratings and GFCI functions, the THHQB is a bolt-on breaker for commercial panelboards, while the THQL is a plug-in breaker for residential load centers.
Does this breaker provide both equipment and personnel protection?
The THHQB2115GFT provides 5mA Class A personnel protection against ground faults, in addition to standard thermal-magnetic protection against overloads and short circuits. It is not an equipment protection (GFEP) breaker, which typically has a higher 30mA trip threshold.
