Questions & Answers

Will this work in an old Westinghouse panel?

1 Answer | 
Answer This Question

While dual function breakers will physically fit, they were developed later so no testing or UL info exist with legacy Westinghouse panels.

        Hi, since this involves a code-related question, I recommend reaching out to your local Authority Having Jurisdiction (AHJ) for guidance.

          We recently installed this for kitchen remodel. However, it failed the final inspection in San Jose because plug in tester cannot trip breaker. Is this expected? Any advice?

          Answer This Question

          Hi, the recommended method for testing our All-in-One circuit breaker is by using the TEST button located on the breaker itself. Please note that a handheld ground fault tester may not reliably trip the breaker. If you need official documentation explaining this, feel free to contact our technical support team at TRC@Eaton.com, and we’ll be happy to provide the letter.

            Does your breaker support plug in tester trip? We recently installed this. In San Jose, inspector test GFCI function by plug in tester to trip the breaker. However, breaker doesn't trip when using plug in tester. Do you know whether this is expected?

                    I’ve been very satisfied with this Eaton surge protector. It feels well made, was easy to install, and gives me peace of mind knowing my electrical equipment is protected from power surges. The quality is excellent, and it has performed reliably without any issues. I would definitely recommend it to anyone looking for dependable whole-home surge protection.

                    Highly Recommended: Reliable and Easy to Install I recently purchased the Eaton BR 20 Amp All-in-One AF/GF Breaker and couldn't be more satisfied with the experience. The online purchasing process was straightforward, and the item was delivered exactly on time. As for the product itself, the installation was incredibly easy—a major plus for anyone looking for a seamless setup. The best part? It worked perfectly and helped me pass the town inspection on the first try. If you're looking for a reliable, code-compliant breaker that saves you both time and hassle, this is the one to get. Pros: • Convenience: Simple online ordering and timely delivery. • Ease of Use: Very user-friendly installation. • Reliability: Passed inspection in one go without any issues.

                    Expensive, but it works. Redesigned from previous models, this is about the same size as standard breakers, it does not extend like the older AFCI breakers. So far so good with no false trips. This covers both AFCI and GFCI. If it wasn't for its price I'd replace some older GCFI outlets for this breaker.
