Product FAQs
5 answersWhich panelboards accept the Federal Pacific NEF437015?
This N-Frame breaker is engineered specifically for legacy Federal Pacific NEF panelboards. It serves as a direct bolt-on replacement for older commercial and industrial distribution systems, eliminating the need for complex retrofits.
What are the wiring and termination specifications for this breaker?
The NEF437015 features standard load-side lug terminals designed to accept conductors ranging from 14 AWG to 2 AWG. It mounts to the panel bus using a secure bolt-on connection to ensure stable mechanical and electrical contact.
How does the trip unit function on the NEF437015?
It utilizes a fixed thermal-magnetic trip unit with long-time and instantaneous (LI) trip functions. This non-interchangeable design provides standard overload and short-circuit protection for 15-amp branch or feeder circuits in legacy systems.
Is the Federal Pacific NEF series still in active production?
No, Federal Pacific Electric is obsolete and no longer manufactures new equipment. The NEF437015 is a legacy component used strictly for maintaining existing NEF panelboards when a complete system upgrade is not immediately viable.
What should be considered before installing a replacement FPE NEF breaker?
Due to the obsolete nature of Federal Pacific equipment, licensed electricians should thoroughly inspect the existing panel bus for signs of wear, arcing, or thermal damage before installing a replacement breaker. Many jurisdictions and insurance providers recommend planning for a complete panel upgrade.

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.
