Product FAQs

7 answers
Which load centers are compatible with the CHFN120GF breaker?

This breaker is designed exclusively for use in Eaton and legacy Cutler-Hammer Type CH load centers. It features a plug-on mounting design but will not fit in Type BR panels or enclosures from other manufacturers.

Does the CHFN120GF require a plug-on neutral load center?

No. This breaker features a pigtail neutral connection, utilizing a coiled wire that connects directly to the panel's neutral bus bar. It is designed for standard Type CH panels that lack plug-on neutral capabilities.

What is the difference between the CHFN120GF and the CHFP120GF?

The CHFN120GF features a pigtail neutral connection designed for older or standard-neutral load centers. The CHFP120GF is the plug-on neutral (PON) variant of this 20-amp GFCI breaker, engineered strictly for newer Eaton CH PON panels.

Which legacy part numbers does the CHFN120GF replace?

The CHFN120GF is the direct modern replacement for earlier Eaton and Cutler-Hammer 20A GFCI breakers, specifically superseding obsolete catalog numbers CHFGF120 and CH120GF.

Does this breaker provide dual-function AFCI/GFCI protection?

No. The CHFN120GF provides dedicated Ground Fault Circuit Interrupter (GFCI) protection to safeguard against electrical shock. It does not contain Arc Fault (AFCI) detection circuitry.

Can the CHFN120GF be installed on a multi-wire branch circuit with a shared neutral?

No. Because this is a 1-pole GFCI breaker, it monitors the current imbalance between the ungrounded (hot) conductor and its dedicated neutral. Installing it on a shared neutral circuit will cause immediate nuisance tripping.

What wire gauge can be used with the terminals on the CHFN120GF?

The box lug terminals on this breaker are rated to accept copper or aluminum wire sizes ranging from 14 AWG up to 6 AWG. Always verify that your chosen wire gauge meets NEC requirements for a 20-amp circuit.
