Questions about this item

Will the 40 A UBIF breaker fit in the older Federal Pacific NBLP panel I still have?

Yes — it is built for Federal Pacific NBLP commercial panels, so the 40 A two-pole unit mounts directly on the existing bus.

How can I confirm the 120/240 V breaker is seated and carrying load correctly after install?

Snap the bolt-on breaker firmly onto the panel bus, then verify 120 V on each pole to neutral and 240 V across the two poles with a multimeter under load.

Does the box include mounting hardware or do I need separate bolts for the NBLP panel?

The bolt-on breaker arrives ready to mount; no extra bolts or clips are required for a compatible NBLP panel.
