Product FAQs
5 answersWhich panelboards accept the Federal Pacific NF631015 circuit breaker?
This N-frame molded case circuit breaker is specifically designed for legacy Federal Pacific NF panelboards. It uses a bolt-on mounting configuration to connect directly to the panel busbars.
What is the maximum fault current the NF631015 can safely interrupt?
The interrupting capacity depends on the system voltage. It is rated to safely clear faults up to 25kA at 240VAC, 18kA at 480VAC, and 14kA at 600VAC. Always verify that the available fault current at the panel does not exceed these limits.
What wire gauge range is supported by the NF631015 terminals?
The standard lugs on this 15A breaker accommodate conductors from 14 AWG up to 1/0 AWG. Verify that your conductor size and insulation type align with local electrical codes for a 15-amp circuit.
Are the trip settings adjustable on the NF631015?
No. This breaker is equipped with a fixed thermal-magnetic trip unit. Both the Long-Time (thermal) and Instantaneous (magnetic) trip functions are factory-set and cannot be adjusted in the field.
Is the NF631015 part of the residential Stab-Lok series?
No. The NF631015 is a commercial-grade, bolt-on molded case circuit breaker belonging to the N-Frame family. It is not part of the residential Stab-Lok line, which utilizes a different plug-on design.
