Is the NF631030 a direct replacement for existing Federal Pacific N-Frame breakers?
Yes, this is an exact replacement for existing 30A, 3-pole NF-series breakers. It matches the original physical dimensions and bolt-on mounting configuration required for Federal Pacific NF panelboards.
Are the thermal and magnetic trip settings adjustable on this model?
No, the NF631030 features a non-interchangeable trip unit with fixed long time and fixed instantaneous trip functions. The trip curve cannot be adjusted in the field.
What wire sizes are compatible with the lugs on the NF631030?
The factory-installed load lugs accept wire gauges ranging from 14 AWG up to 1/0 AWG. Ensure proper torque specifications are followed during installation as required by local electrical codes.
