Product FAQs
5 answersCan I install the NE234050 in a standard Federal Pacific Stab-Lok panel?
No. The NE234050 is a bolt-on N-frame breaker specifically designed for commercial Federal Pacific NE panelboards, not residential Stab-Lok load centers.
What type of wire can be used with the NE234050 terminal lugs?
The lugs accommodate wire gauges from 14 AWG to 2 AWG. Ensure you use properly sized conductors based on the 50-amp rating and local electrical codes.
Is the NE234050 suitable for direct current (DC) applications?
Yes, in addition to its 240V AC rating, this thermal-magnetic breaker is rated for up to 250V DC systems, providing a 5kA interrupting capacity for DC circuits.
Are there direct aftermarket replacements for the Federal Pacific NE234050?
Yes, because original Federal Pacific breakers are legacy components, aftermarket manufacturers like Connecticut Electric (UBI) produce direct bolt-on replacements that fit the same NE panelboards.
Does the NE234050 feature an adjustable trip setting?
No, this breaker uses a fixed thermal-magnetic trip mechanism for both long-time and instantaneous (LI) functions. The trip points cannot be manually adjusted in the field.
