Product FAQs
4 answersWhat panelboards accept the NEF421020 circuit breaker?
This N-frame breaker is designed for bolt-on installation in legacy Federal Pacific NEF, CDP, and NDP series industrial panelboards.
Is the NEF421020 part of the residential Stab-Lok series?
No. The NEF421020 is a commercial and industrial N-frame molded case circuit breaker. It uses a bolt-on connection and is completely different from the residential Stab-Lok plug-on breakers.
Does the NEF421020 require special mounting hardware?
Depending on the enclosure, installing this breaker into Federal Pacific NDP or CDP panelboards typically requires specific bus connection hardware or strap kits, such as the NDPNE or NEF1K kits, to adapt the N-frame breaker to the panel bus.
Can the NEF421020 be used for reverse feed applications?
Yes. This thermal-magnetic breaker supports reverse feed setups, allowing it to be safely backfed in compatible commercial and industrial applications.

Superbreakers did a great job for us. We called and asked if the breakers were actually in their possession. Withing 30 minutes they called us back (which is rare these days), and we got our breakers the next morning.
