Multiple circuits (separate neutral) in a conduit with receptacles


I am running multiple circuits (3 circuit separate neutral) in a 1/2" conduit. They will go to several junction boxes as well as junction which has receptacle on it. Is this ok to have a junction box with several circuits passing through (without connection) with receptacle?

You can pass circuits through junction boxes, as long as you do not exceed the fill capacity of the box. Also, depending on the gauge of the THHN in your conduit (and the type of conduit itself), you may be pushing the fill capacity of 1/2 conduit with three circuits using independent neutrals.

You can get 9 #12 THHN in a 1/2" EMT conduit.

Is this single phase or 3 phase?

Single phase can not share 3 circuits.

But the neutrals are not shared.

This is single phase. What do you mean by cannot share 3 circuits?

If your intention is to share one neutral with three circuits on your single phase service.....you absolutely CANNOT do it.

Not applicable to your install. You have 3 hots and 3 neutrals.

I read the OP and wasn't sure what thone was going to do. Still haven't heard enough from thone to really know. It's the "seperate neutral", not seperate neutrals that made me question it.

My bad!

Yes, I am planing to run separate neutrals for each circuit.

Thanks to you all!

And you will bond all boxes, right?
