Product FAQs
6 answersWhich panelboards accept the Federal Pacific NEF214090 circuit breaker?
This N-frame breaker is specifically engineered to mount into legacy Federal Pacific commercial and industrial panelboards. It is not compatible with residential Stab-Lok load centers.
Is there a modern replacement available for the NEF214090?
Yes, because original Federal Pacific breakers are legacy components, facility managers often use the UBIF090N as a verified aftermarket substitute. It is designed to fit the exact same N-frame enclosures.
What wire gauge is required for installing the NEF214090?
The factory-installed load-side lugs accept wire sizes from 4 AWG up to 1/0 AWG. Ensure your conductor sizing aligns with the 90-amp rating and local electrical codes for your specific application.
How does the interrupting capacity of the NEF214090 change across different voltage systems?
The breaker provides a 14kAIC rating for standard 277VAC commercial lighting circuits, but the interrupting capacity increases to 25kAIC when installed in 120VAC applications. It also supports 125VDC systems with a 10kAIC rating.
How is the NEF214090 secured to the panelboard bus?
This model utilizes a bolt-on connection rather than a plug-on design. This ensures a highly secure, vibration-resistant contact suitable for commercial and industrial environments.
What type of trip unit is installed in the NEF214090?
It features a non-interchangeable thermal-magnetic trip unit with fixed long-time and instantaneous (LI) functions, providing standard overload and short-circuit protection.

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.
