Product FAQs
7 answersWhich load centers are compatible with the GFTCB220 circuit breaker?
This plug-on breaker is designed for use in Eaton Type BR load centers. It is also backward compatible with legacy Westinghouse, Challenger, and Bryant panels that accept Type BR breakers.
Does the neutral pigtail on the GFTCB220 need to be connected if the 240V load does not use a neutral?
Yes. The white neutral pigtail must be landed on the panel's neutral bar for the breaker's internal ground-fault sensing circuitry to operate, even if the dedicated 240V load does not require a neutral wire.
What is the ground-fault trip sensitivity of the GFTCB220?
This breaker features a 5mA trip threshold, meeting UL 943 Class A requirements for personnel protection against electric shock in wet or damp locations.
Can I use the BRN220GF in place of the GFTCB220?
Yes. The BRN220GF is Eaton's newer catalog number for this exact form factor. It serves as a direct, code-compliant replacement for the legacy GFTCB220 and GFCB220 breakers in Type BR load centers.
What conductor materials and sizes are supported by the GFTCB220 terminals?
The box lugs accept both copper and aluminum wiring, accommodating conductor sizes from 14 AWG up to 4 AWG.
What type of trip functions does the GFTCB220 provide?
It utilizes a thermal-magnetic trip unit providing Long-Time (overload) and Instantaneous (short-circuit) protection, combined with Ground-Fault sensing (LIG) for comprehensive circuit and personnel safety.
Is the GFTCB220 suitable for straight 240V loads that do not require a neutral?
Yes. While it is rated for 120/240VAC multi-wire branch circuits, it can also protect straight 240V equipment like well pumps or air conditioners. Just remember the breaker's own neutral pigtail must still be connected to the panel.

Jake was the guy that handled my order. Everything went smooth, he was polite and knowledgeable!
- RCRebecca C.Verified BuyerRated 1 out of 5 stars8/11/25wrong breaker and over charged for shipping.
Sent me the wrong breaker and over charged me for shipping. When I ordered my breaker, I paid an extra $24 for UPS ground shipping so that I would get the breaker quicker than normal shipping. When I called in they told me that the normal shipping was already UPS ground. So, I paid for nothing. Also did not send the breaker that I had queued up to purchase.

Initially placed order for wrong breaker. I called them up and the agent quickly cancelled wrong order, and placed the order for the correct breaker. It was a very quick and painless process. Breaker shipped and arrived quickly. This breaker was out of stock at a lot of places and was hard to find. Super breakers had it in stock and shipped promptly.
