Product FAQs
5 answersCan I install the NEF425070 in a residential FPE Stab-Lok load center?
No. This is a commercial bolt-on molded case circuit breaker designed exclusively for Federal Pacific NEF panelboards. It will not fit or operate in residential Stab-Lok load centers.
Is the Federal Pacific NEF425070 still in active production?
No. Federal Pacific Electric (FPE) ceased operations decades ago. The NEF series consists of obsolete legacy components, meaning replacements must be sourced from specialized inventory rather than current factory production.
Can the NEF425070 be utilized in industrial DC control circuits?
Yes. In addition to standard AC applications, this breaker is rated for direct current systems up to 250VDC. It provides a 10kA interrupting capacity for DC distribution and control panels.
What are the wire size requirements for the terminal lugs?
The factory lugs on this breaker accept conductor sizes from 4 AWG up to 1/0 AWG. Always verify that your selected wire gauge and insulation temperature rating meet National Electrical Code requirements for a 70A circuit.
Does the NEF425070 share the same safety issues as FPE residential breakers?
The widely documented safety controversies surrounding Federal Pacific primarily involve their residential Stab-Lok line. The NEF series is a different commercial molded case design. Regardless, all legacy electrical equipment should be thoroughly evaluated and installed by a qualified professional.

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.
