Product FAQs
7 answersWhich panelboards are compatible with the NEF431015 circuit breaker?
This breaker is designed for use in legacy Federal Pacific NEF and CDP series panelboards. It bolts directly to the busbar in these specific enclosures.
Is the Federal Pacific NEF431015 still in active production?
No. Federal Pacific Electric is no longer in business, making the NEF series obsolete. Replacements are typically sourced from existing legacy inventory or specialized aftermarket manufacturers.
Are there direct aftermarket replacements for the NEF431015?
Yes, manufacturers like Eaton produce UL classified aftermarket replacements for legacy Federal Pacific frames. However, exact cross-references depend on the specific panelboard bus structure and local code requirements.
How does the NEF431015 mount into the panelboard?
This breaker features a bolt-on mounting style. It secures directly to the panelboard busbar using screws, providing a firm and stable connection suitable for commercial and industrial environments.
What wire sizes are accepted by the lugs on this breaker?
The terminals on the NEF431015 accommodate wire ranging from 14 AWG to 2 AWG. Ensure proper torque specifications are followed during installation.
Are the trip settings adjustable on the NEF431015?
No, this breaker features a fixed thermal magnetic trip unit. Both the long-time overload and instantaneous short-circuit trip functions are factory set and cannot be adjusted in the field.
Does the NEF431015 share the same design as FPE Stab-Lok breakers?
No. The NEF series is a commercial molded case circuit breaker with a bolt-on connection. It does not use the residential Stab-Lok plug-on design.

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.
