Product FAQs
5 answersWhat equipment is the Federal Pacific NM632800 designed to fit?
This N-frame breaker is an exact replacement for legacy Federal Pacific NM panelboards and switchboards. It features a bolt-on mounting style that secures directly to the bus without requiring aftermarket adapters.
What are the wire size requirements for the NM632800 lugs?
The included load-side lugs accommodate three conductors per phase. The acceptable wire gauge range is 3/0 AWG to 500 kcmil for each conductor.
What type of trip unit is installed in the NM632800?
It utilizes an interchangeable thermal-magnetic trip unit equipped with Long-Time and Instantaneous (LI) protection. The thermal element is fixed, while the magnetic instantaneous trip is adjustable to coordinate with your system's fault current requirements.
Is the Federal Pacific NM632800 still in active production?
No, Federal Pacific Electric (FPE) is obsolete and no longer manufactures new breakers. However, legacy N-frame breakers like the NM632800 are still sourced to maintain and service existing FPE switchboards and distribution panels.
What safety precautions should be taken before installing the NM632800?
Always ensure the panelboard or switchboard is fully de-energized before installation. Verify that the system voltage and available fault current do not exceed the breaker's maximum ratings. Installation should only be performed by a qualified electrical professional.
