About This Product

The 2014 NEC has mandated Ground Fault and Arc Fault circuit protection on many 15 Amp and 20 Amp kitchen and laundry circuits. General Electric offers both Ground Fault and Combination Arc Fault (GFCI and CAFCI) protection in a simple to apply and cost effective solution. GFCI protection guards against ground fault as an effective means of preventing electrical shocks. GFCI circuit breakers accomplish this by detecting when current is "leaking" somewhere outside its intended path. If your body provides path to ground for this "leakage" you could be burned, shocked or even electrocuted. CAFCI protection guards against damage or fires which can result from arcing and sparking that can arise from deteriorated wires, poor connections and breaches in wire insulation. With more than 67,000 home fires claiming more than 485 lives and injuring 2,300 victims annually, the added safety provided by CAFCI protection is an important step forward in reducing this risk.

Questions & Answers

Will this trip when using standard kitchen appliances (e.g., food processor even on pulse, blender, mixer) even though it has variable speeds?
BySep 24, 2024
1 Answer | 
Answer This Question

This breaker is designed to protect against arc faults and ground faults, not against surges caused by appliances. While some users have reported nuisance tripping with certain electronics, standard kitchen appliances like food processors, blenders, and mixers should not cause the breaker to trip unless there's an actual arc fault or ground fault present.

Are the dimensions correct? Is this really 6 inches wide and long (across both columns on the breaker), OR it fits the standard breaker of 1 in H x 2.25 W?
BySep 24, 2024
1 Answer | 
Answer This Question

The dimensions listed are 6.63" W x 1.32" H x 6.57" D. A standard single-pole breaker is approximately 1" H x 2.25" W. This is a dual-function breaker, so it's larger than a standard single-pole breaker.

Does this protect against ground fault currents DC content (pulsating DC)?
ByAug 5, 2023
1 Answer | 
Answer This Question

This breaker is designed to protect against ground faults, but it primarily focuses on AC ground faults. The specifications and documentation do not mention any specific protection against DC ground fault currents, including pulsating DC. For further clarification or specific DC ground fault protection requirements, it is best to consult a qualified electrician.

      Buy The New ABB-Labeled Version; It's From the Same Folks Who Used to Make Them For GE.
      Too many nuisance trips. As of April 26, 2026 in most parts of the country (except Texas) you will find the 20 Amp. version out of stock. It will never be in stock again as ABB is now only selling it under the ABB name. Home Depot is selling it under Internet # 331122690, Model # THQL1120DFA, Store SKU # 1011988701. It is the same THQL1120DF as the General Electric following ABB's purchase of GE's circuit breaker division. It is manufactured in the Dominican Republic. Look at the reviews for the newer THQL1120DFA; a lot of people say they bought them because early ABB production was too sensitive (READ: Nuisance Tripping). I bought the package shown in the photos off eBay. It is probably a Home Depot store return. I can confirm it works in place of GE branded breakers. Don't go running to a Home Depot store that shows it has one GE breaker in stock. That one was shoplifted a long time ago.

        Goes bad quickly.
        I installed these for my remodel and over two years have had 6 go bad. They are highly sensitive and once they’ve started tripping it just spirals downwards from there.

          Recently remodeled my basement and my electrician recommended these circuit breakers. They provide both GFCI and AFCI protection in one unit. Pricey but worth the cost.

          This breaker worked perfect for my remodel job
          by
          It is to early to make a decision about these breakers. They initially appear to be OVERLY sensitive, anything with motors (refrigerator, microwave, furnace) seem to trip them. I have only had them for a week, so it is to early to recommend, or not recommend them.

          The unit itself is easy to install. However, the packaging is very poor. It is not descriptive, and the package does not allow you to see the reverse side of the breaker. I needed a breaker with a double clip. Because this is a controlled item at the store, it is very hard to get help. Clear packaging would have helped someone like me, a nonprofessional, match up what I needed. As it was, I had to got back to the store three times, and several returns, to get the correct breaker.
