PVC into a metal J-box leaving in EMT. Not service, no splices in box just a pull can. Does this can need to be grounded? I'm not seeing where it needs to be. Did I miss something?
Ground this or not?

It needs to be bonded on one end or the other...end of the EMT.
What volt?

What's on the other end of the EMT?

Is there an EGC so that the EMT can be grounded where it terminates. IMO, the EMT must be grounded but the JB would not need a jumper to bond it. Actually it would be if the EMT was grounded.

If the EMT is terminated in a grounded enclosure on the other end it would provide the grounding means for this pull box. If we are dealing with >250 volts to ground, verification of listed for grounding would be an issue.

Roger, I don't think I understand your statement. As long as the EMT is bonded to the EGC on one end and the box is bonded to the EMT on the other end and why would if make a difference which is the feed side?

I think Roger was saying if the emt came from the panel then there would be no need to bond it, however if the PVC was from the panel then the emt needed bonding.
Curt, Dennis is correct, what I was saying is, if the EMT is from the distribution side (the panel) it and the box would already be bonded, if the PVC is from the distribution side we would have to add an EGC and bond the box which will (should) provide the bonding to the EMT.

I still don't follow that explanation. It does not matter if the metallic raceway is grounded at the line or load end.
Of course it doesn't matter at which end the EGC is established but, read the OP and tell me where an EGC is said to be in place on either side.
The way I read the question is that there is a metallic raceway on one side of a metal box and on the other side there is PVC, now the question goes, is it necessary to bond the box which would in turn bond the metallic raceway? If the EMT is from the bonded side (the panel) nothing else needs to be done, if the PVC is the line side with no other bonding an EGC must be established.

So what you are saying is that if it's not bonded you need to bond it.
Makes perfect sense to me.

Its 480V 3ph 4W plus EGC, feeder for panel.

The feed end starts in PVC then hits the metal pull box, out of the pull box is EMT to the new panel. EGC will be in pipe.

The EGC is your saving grace. No bond required, unless splices are made in the box in question.

That is what I thought. Like I said its just a pull box, no splices will be in there.
