Product FAQs
7 answersWhich load centers accept the GFCB220 circuit breaker?
This breaker is designed specifically for Eaton and Cutler-Hammer Type BR load centers. It requires two standard 1-inch spaces for its plug-on mounting connection.
How is the neutral wire configured on this GFCI breaker?
The GFCB220 utilizes a pigtail neutral design. The coiled white wire must be terminated directly to the neutral bus bar in the panel to power the internal ground fault circuitry.
What is the tightening torque for the load terminals?
The box lug terminals should be torqued to 25 lb-in when securing 14-4 AWG copper or aluminum conductors.
How are load neutrals handled when wiring this 2-pole GFCI?
For 120/240V circuits, the load neutral must be connected directly to the neutral lug on the breaker. The breaker's white pigtail is then connected to the panel neutral bar.
What is the ground fault trip threshold for this model?
This breaker provides Class A ground fault protection, which is calibrated to trip when a ground fault leakage current of 5 mA is detected.
How does the trip mechanism operate on the GFCB220?
It features a thermal-magnetic trip unit for standard overload and short-circuit protection, combined with internal electronic circuitry that continuously monitors for ground fault imbalances.
Can this breaker be used to protect circuits in wet locations?
While the breaker itself must be installed in an appropriately rated enclosure, it is designed to provide ground fault protection for branch circuits extending into wet locations such as pool pumps, hot tubs, and outdoor receptacles.

- CKChris K.Rated 5 out of 5 stars7/13/23works great
I enjoy ordering from this co.. They even pulled through on a 1200A switchgear breaker that couldn't be sourced through Schadler Yesco. Really solid Co..

Thanks
- PNPaul N.Rated 5 out of 5 stars9/13/21Exactly what I needed at a great price and fast delivery
I have a well pump house that runs on 220v and the last time I needed to replace the breaker there was a local "Electrical" supply store where I could buy this part - ok, so it was like 15-18 years ago. Fast forward to 2021 and every local place I called basically said, "...oh yeah, that's a common breaker, we don't carry it." To the rescue comes SuperBreakers! Best price, fast shipping, perfect fit. Shut off power, popped out old breaker, popped in my new SuperBreaker, power back on and well is pumping again. Will definitely use SuperBreaker for all my breaker needs.
