Description
Built for residential safety, the GE THHQL1115GFT provides 15 amps of ground-fault protection. It features an integrated self-test mechanism that routinely verifies internal circuitry to ensure continuous 5mA Class A defense. This plug-on breaker mounts into GE PowerMark Gold, ABB ReliaHome, and A-Series panelboards. It serves as an exact upgrade for the older THHQL1115GF model, utilizing a standard pigtail neutral. Rated for 22kAIC at 120VAC, the unit is both HACR and SWD rated.Specifications

Product FAQs
8 answersWhich load centers accept the THHQL1115GFT breaker?
This plug-on breaker is compatible with GE PowerMark Gold load centers, ABB ReliaHome load centers, and GE A-Series panelboards.
What is the difference between the THQL1115GFT and the THHQL1115GFT?
The primary difference is the short-circuit interrupting rating. The standard THQL1115GFT is rated for 10kAIC at 120V, while the THHQL1115GFT is the high-interrupting capacity version rated for 22kAIC at 120V.
Can the THHQL1115GFT replace an older THHQL1115GF breaker?
Yes, the THHQL1115GFT is the direct replacement for the legacy THHQL1115GF. The T suffix indicates the addition of an automatic self-test feature to comply with updated UL 943 standards.
What level of ground fault protection does the THHQL1115GFT provide?
This breaker provides Class A ground fault protection for personnel safety. It is calibrated to trip when it detects a ground fault leakage current of 5mA.
How is the neutral connection wired on this GFCI breaker?
The THHQL1115GFT utilizes a standard pigtail neutral. The coiled white pigtail wire must be terminated directly to the neutral bus bar in the panelboard to power the internal GFCI circuitry.
How does the self-test feature operate on this unit?
The integrated self-test mechanism automatically runs periodic diagnostic checks to verify the internal ground fault circuitry is functioning properly. If a failure is detected during a self-test, the breaker will trip and must be replaced.
When is a 22kAIC rating required over a standard 10kAIC breaker?
A 22kAIC rating is required when the available fault current at the panel exceeds 10,000 amps. This is common in commercial applications or residential services located in close proximity to utility transformers.
What does the LIG trip function code indicate on this breaker?
The LIG designation means the breaker provides Long-Time (thermal overload), Instantaneous (magnetic short-circuit), and Ground Fault protection in a single unit.
