Product FAQs
7 answersWhich panelboards accept the Federal Pacific NEF111020?
This N-frame molded case circuit breaker is engineered specifically for bolt-on installation in legacy Federal Pacific NEF commercial panelboards. It is not compatible with residential Stab-Lok load centers.
What type of mounting connection does this breaker require?
The NEF111020 utilizes a bolt-on mounting configuration, which provides a secure, vibration-resistant connection to the panelboard busbar compared to standard plug-in designs.
What are the wire gauge requirements for the terminal lugs?
The load-side lugs on this 20A breaker accommodate wire sizes ranging from 14 AWG up to 2 AWG. Always verify local electrical codes for proper conductor sizing based on the 20A rating.
What is a direct aftermarket replacement for the NEF111020?
The UBIF20N is a verified equivalent substitute for this legacy N-frame breaker, offering the same physical dimensions and electrical ratings for NEF panelboards.
Are the trip settings on the NEF111020 adjustable?
No. This breaker features a fixed thermal-magnetic trip unit. The long-time and instantaneous (LI) trip functions are factory-calibrated and non-interchangeable.
Is the NEF111020 suitable for HVAC equipment and lighting circuits?
Yes. This breaker is HACR rated for use with heating, air conditioning, and refrigeration equipment. It is also SWD (Switching Duty) rated for switching 120V fluorescent lighting loads.
Can the NEF111020 be used in reverse feed applications?
Yes. This breaker is rated for reverse feed setups, allowing it to be back-fed safely when required by the specific panelboard or circuit design.

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.
