I have a 200A main panel I am running a 2" conduit with the main feeder for this panel. Before penetrating the 200A main panel I set a 12"x12" x4" junction box then ran the conduit inside the 200A main panel with the main feeder. Inside the same 2" conduit I am running 1-120V circuit to a receptacle circuit.
Is it NEC acceptable to run line and load power in the same conduit? If it is where in the NEC book does it state this.

Branch circuits and feeders can be in the same conduit.

Service conductors and conductors for sure 'nuff emergency circuits (among other things) cannot share conduits with anything else.

I like all of 300.3(C)(1) or (2) your answer really in (1) but its good to remember (2) exists as well... :grin:

& what He said...

All i could think then of was:

Look at Figure 90.3, & article.

Articles:
1-4 gets the wire in
5-7 adds or subtracts to its application\style

Yes and that what's we do address, the Wiring to the Service!

Welcome !

If it was a strait pull thru that junction box with no splices, there may be another issue.
