Product FAQs
8 answersWhat load centers are compatible with the Eaton CHFN220GF?
This breaker is designed exclusively for Eaton CH series load centers. It requires two 3/4-inch spaces and connects to the neutral bar using the included pigtail wire.
Can I use the CHFN220GF to replace an older CH220GF or CHN220GF?
Yes, the CHFN220GF is the direct, current-generation replacement for legacy CH220GF and CHN220GF 20A GFCI breakers. It fits the same CH series panels and provides the same 5mA Class A ground fault protection.
Does the CHFN220GF require a plug-on neutral panel?
No, this breaker features a pigtail neutral connection. It can be installed in standard Eaton CH load centers by wiring the pigtail directly to the panel's neutral bus bar, making it compatible with older legacy panels.
How much panel space does the CHFN220GF require?
As a 2-pole breaker in the CH family, it requires two standard 3/4-inch spaces in your load center.
What wire sizes are accepted by the CHFN220GF terminals?
The box lug terminals on this breaker accept copper or aluminum wiring from 14 AWG up to 3 AWG.
What level of ground fault protection does the CHFN220GF provide?
It provides Class A ground fault protection, which trips at 5mA to protect personnel from electrical shock hazards in wet or damp locations.
How can I tell if the CHFN220GF has tripped due to a fault?
The CHFN series features a visual trip flag and a trip-to-OFF handle mechanism, making it easy to identify when the breaker has tripped compared to one that was manually turned off.
What applications is the CHFN220GF suitable for?
This 2-pole, 120/240VAC breaker is ideal for 240V equipment or multi-wire branch circuits requiring 20 amps and GFCI protection, such as pool pumps, hot tubs, or outdoor receptacles.
