Product FAQs
6 answersWhat panelboards are compatible with the Federal Pacific NEF427080?
The NEF427080 is designed for use in legacy Federal Pacific NEF and CDP series panelboards. When installing this N-frame breaker into a CDP panelboard, specific twin mounting hardware kits, such as the NEF1K, are typically required to adapt the breaker to the bus.
Is the NEF427080 part of the Federal Pacific Stab-Lok series?
No. The NEF427080 is a commercial bolt-on molded case circuit breaker and is not part of the residential Stab-Lok plug-on series known for safety issues. However, because Federal Pacific is no longer in business, many facility managers and insurance providers still recommend evaluating all legacy FPE equipment for potential upgrades.
Can the NEF427080 be used in DC electrical systems?
Yes, this thermal-magnetic breaker is rated for both AC and DC applications. It supports up to 250VDC with a 10kA interrupting capacity, making it suitable for specialized industrial DC circuits in addition to standard 240VAC and 480VAC systems.
What type of trip unit does the NEF427080 use?
This breaker features a fixed thermal-magnetic trip unit with long-time and instantaneous (LI) trip functions. The fixed thermal element protects against sustained overloads, while the fixed magnetic element responds to sudden short circuits.
What wire sizes do the lugs on the NEF427080 accept?
The factory lugs on this 80A breaker are sized to accept wire gauges ranging from 14 AWG up to 1/0 AWG. Always ensure proper torque specifications are followed during installation to maintain a secure and compliant connection.
Is the Federal Pacific NEF427080 still manufactured by the original company?
Federal Pacific Electric (FPE) is no longer in business, making original OEM production obsolete. Replacements for the NEF-7 frame are sourced through specialized legacy electrical distributors or via verified aftermarket exact-fit substitutes designed to mount into existing FPE panelboards.

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.
