Designed for older residential load centers, this single-pole 20A ground-fault interrupter provides essential 5mA Class A personnel protection. It installs seamlessly into Federal Pioneer and Federal Pacific Stab-Lok panels, serving as an exact replacement for the discontinued NA120GF model. The unit requires two panel spaces and features a built-in push-to-test button to verify proper operation, helping facilities meet modern NEC requirements for damp or wet locations.

Product FAQs
6 answers
Is this breaker compatible with older US Federal Pacific Electric (FPE) panels?
Yes. Federal Pioneer is the Canadian equivalent to Federal Pacific. This breaker is fully compatible with both Federal Pioneer and Federal Pacific (FPE) Stab-Lok load centers.
Does this breaker replace the discontinued NA120GF?
Yes, the NAGF20FED serves as a direct replacement for the obsolete FPE and Challenger NA120GF 20A single-pole GFCI breakers.
How many panel spaces does the NAGF20FED require?
Although it is a 1-pole breaker, the GFCI circuitry requires it to occupy two standard Stab-Lok panel spaces.
What level of ground-fault protection does this breaker provide?
It provides 5mA Class A personnel protection, which is required by the NEC for damp or wet locations.
How is the neutral connection made for this GFCI breaker?
It features a pigtail neutral wire that must be connected directly to the panel neutral bus bar to power the ground-fault detection circuitry.
How do I verify the ground-fault protection is working?
The breaker includes a built-in push-to-test button. It should be tested periodically to ensure the personnel protection circuitry is functioning correctly.
