What wire sizes are accepted by the lugs on this breaker?
The terminal lugs accommodate wire sizes ranging from 14 AWG to 2 AWG.
Is the NEF217020 part of the residential Stab-Lok series?

Yes, the NEF217020 is rated for DC applications up to 125VDC with an interrupting capacity of 10kA.
How does this breaker connect to the panelboard bus?
It utilizes a secure bolt-on connection, which is required for commercial NEF and CDP panelboards to ensure a solid contact that resists vibration.
Are the trip settings adjustable on this breaker?
No, it features a fixed thermal and fixed magnetic trip unit that cannot be adjusted in the field.
Is Federal Pacific still manufacturing the NEF217020?
Federal Pacific is a legacy brand and original production has ceased. However, exact replacement units are still sourced to maintain existing NEF and CDP panelboards without requiring a full panel upgrade.
Can I install this breaker in a standard residential load center?
No. This is an N-Frame commercial breaker designed specifically for bolt-on NEF and CDP panelboards. It will not fit in standard residential plug-on load centers.

The LI designation means the breaker provides Long-Time and Instantaneous trip functions for 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.
