Product FAQs
7 answersWhich panelboards accept the NEF214100 circuit breaker?
This breaker is a direct replacement component designed specifically for legacy Federal Pacific (FPE) NEF panelboards. It bolts directly into the existing enclosure without the need for aftermarket mounting adapters.
Is the NEF214100 compatible with Federal Pacific Stab-Lok residential panels?
No. The NEF214100 is a commercial N-Frame molded case circuit breaker with a bolt-on mounting style. It will not fit into residential Stab-Lok load centers, which require specialized plug-in breakers.
How is the NEF214100 secured to the busbar?
It features a bolt-on connection type that fastens directly to the panelboard bus. This provides a secure, vibration-resistant contact that is required in many commercial and industrial distribution systems.
What are the acceptable wire sizes for the NEF214100 lugs?
The factory lugs accommodate wire gauges from 4 AWG to 1/0 AWG. Ensure you torque the terminals to the manufacturer specifications printed on the breaker label during installation to prevent thermal issues.
Can the NEF214100 be used in DC control circuits?
Yes. In addition to standard AC distribution, this breaker is rated for 125VDC applications with a 10kAIC interrupting capacity, making it suitable for specific industrial DC control and power systems.
Can the trip settings on the NEF214100 be adjusted in the field?
No, this breaker is built with a fixed thermal and fixed magnetic trip unit. The long-time and instantaneous trip functions are factory-calibrated and non-interchangeable.
What frame group does the NEF214100 belong to?
It is part of the Federal Pacific N Frames group. When sourcing replacement hardware or enclosures, ensure they are specifically rated for NEF frame dimensions and bolt patterns.

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.
