Built to safeguard 240V circuits in damp environments, this two-pole 20A interrupter delivers reliable 5mA Class A ground-fault protection. It mounts into classic Federal Pacific and Federal Pioneer Stab-Lok enclosures, acting as a reliable substitute for the obsolete NA220GF. Occupying four panel spaces, the thermal-magnetic design includes a common trip function and a convenient test button to ensure ongoing compliance with residential electrical safety codes.

Product FAQs
6 answers
Will the NAGF220FED fit my Federal Pacific Electric (FPE) panel?
Yes, this breaker is designed to fit both Federal Pioneer and Federal Pacific Stab-Lok load centers. It installs directly onto the stab-style busbar without requiring aftermarket adapter kits.
How many panel spaces does this 2-pole GFCI breaker require?
The NAGF220FED requires two standard 1-inch spaces in a Stab-Lok load center.
Does the NAGF220FED require a neutral connection to function properly?
Yes, this GFCI breaker features a pigtail neutral wire that must be connected to the panel neutral bus bar to accurately monitor current imbalances and provide ground fault protection.
How do I verify the ground fault protection is working after installation?
The breaker includes a built-in push-to-test button. Once installed and energized, pressing this button should immediately trip the breaker, confirming the GFCI circuitry is functioning correctly.
What level of ground fault protection does this breaker provide?
The NAGF220FED provides Class A personnel protection, meaning it is calibrated to trip when it detects a ground fault current of 5mA or more.
Can I use this breaker to meet code requirements for wet or damp locations?
Yes, Class A GFCI breakers like the NAGF220FED are designed to meet NEC requirements for personnel protection in areas prone to moisture, such as bathrooms, kitchens, garages, and outdoor receptacles.
