Product FAQs
6 answersCan I install the NB232020 in a standard Federal Pacific residential load center?
No. This is a bolt-on breaker designed specifically for commercial Federal Pacific NB panelboards. It is not compatible with residential Stab-Lok load centers, which require plug-on breakers.
What is the Connecticut Electric substitute for the NB232020?
The UBIF320NB is the direct aftermarket replacement manufactured by Connecticut Electric. It provides the same 20A, 3 pole configuration and bolt-on mounting for legacy NB panels.
How is the NB232020 secured inside the panelboard?
It uses a bolt-on mounting configuration that fastens directly to the busbar of Federal Pacific NB panelboards, providing a secure mechanical and electrical connection for commercial applications.
What are the wiring requirements for the NB232020 terminals?
The included load side lugs are rated for both aluminum and copper conductors. They can accommodate wire gauges from 14 AWG up to 2 AWG, allowing flexibility for various commercial circuit runs.
Does the NB232020 use the Stab-Lok connection design?
No. The NB series utilizes a bolt-on connection for commercial panelboards. It does not feature the Stab-Lok plug-on design found in older Federal Pacific residential load centers.
What type of trip unit is equipped on the NB232020?
It features a fixed thermal magnetic trip unit with long-time and instantaneous (LI) functions. This provides standard overload and short-circuit protection without adjustable settings.
