Product FAQs
6 answersWhich panelboards are compatible with the Federal Pacific NB231080?
The NB231080 is designed for use in Federal Pacific NBLP, NBC, NBDP, and CDP panelboards.
What wire sizes are accepted by the lugs on the NB231080 breaker?
The terminal lugs on this breaker accept wire gauges ranging from 4 AWG to 1/0 AWG.
What does the LI trip function on the NB231080 indicate?
The LI designation means this thermal-magnetic breaker provides both long-time overload protection and instantaneous short-circuit protection. The trip settings on this model are fixed and cannot be adjusted in the field.
Does the NB231080 require special mounting hardware?
As a bolt-on breaker, it secures directly to the busbars of compatible Federal Pacific panelboards using standard bolted connections. It does not snap or plug into place.
Are there direct aftermarket replacements for the Federal Pacific NB231080?
Federal Pacific Electric is no longer in business. Because aftermarket manufacturers do not produce direct replacements for the NB frame, you must use an original Federal Pacific NB231080 to maintain compatibility with your existing panelboard.
Is the NB231080 part of the Federal Pacific Stab-Lok residential line?
No. The NB231080 is a bolt-on molded case circuit breaker designed for commercial panelboards like the NBLP and CDP series. It does not use the Stab-Lok plug-on design found in residential load centers.
