Pull box bonding required?

[Isaiah]

Does a pull box (has no terminations) have to be bonded? Does this meet 250.4(A)4;
that is “likely to become energized”?

Is the pull box metal and is the raceway metal?

The box is non metallic but the raceway is metallic

I would say it does not require bonding

Howe would you bond a non-metallic box?!

You do need to maintain raceway bonding continuity, via EGCs or bonding bushings.

But if the pull box were metal, in my opinion it would still be unlikely to become energized if there’s no terminations

I should clarify most of the PBs are nonmetallic but a few are sheet metal

I know "likely to become energized" is not defined, but I have a hard time imagining an electrical enclosure is not "likely to be energized" just because it doesn't have splices in it. If you can find one electrical inspector who finds that argument acceptable, I'll buy you a sandwich!

Is that actually required if each section of raceway is appropriately bonded on the other ends?

Plastic green screws.

If it's metal and the raceway is metal, isn't it already bonded?

Just want to also add there are other sections that would require the pull box to be bonded that don't use the phrase " likely to become energized".

The boxes have Myers hubs attached. Which sections?

With Meyers hubs use the meyers bonding locknut, it has a screw to attach a bonding jumper

Where a wire type EGC is used, and splices are made in a metallic box, it must be bonded.

If there is no splice in the box, the EGC is not required to be bonded to the box. But the box must be bonded through the raceway.

Non-conductive materials are not required, nor is it possible, to bond them. But the raceway on both ends need to be.

At least that has been my understanding. With the way the last couple weeks have gone, I’m probably wrong.

Likely to become energized does not play a part here because the box and the raceways are covered by 250.4(A)(3), not 250.4(A)(4).

The Scrutite Myers hub provides grounding via the serrated connection without a bonding jumper
