Disconnect needed to know if I could use the same conduit for the line and load or do you have to run separate conduits. Tried to find it in nec but was not able to locate.
 
The prohibition is on service conductors in the same conduit as feeders and/or branch circuit conductors. Generally, you can do it with branch circuit or feeder conductors, but you may need to consider derating.

Also, trying to imagine what you are doing. If the conductors on the load side of the disconnect go to the same cabinet as the supply conductors, there’s marking rules in article 312 that apply for that. Not sure what you’re doing but this may apply to you.

We put in a new hot water heater and the old disconnect is behind the heater and the inspector wants it moved so we were going to use one conduit for line and load do to it is in a really bad location to try and get to conduits. Thanks Curtis

Yes you can run both line and load in the same raceway. As Josh stated you may need the derate if you have more than 3 CCC's in the single raceway. If the raceway is 24" or less no derating required.
 
Them breaker locks are legal and we have used them for hardwire double ovens, dishwashers and hoods. Just don't like how easy they come off when AC guys or inspectors access panel. Rarely do they put them back where they belong.
 
We found an area where a bunch of new homes where built an inspectors allowing breaker locks in lieu of disconnects for air handlers. Nec 440.14 and we mentioned it and it really ticked off the builders when he started enforcing
 
Think of a light (or any) switch, line and loads in the same raceway or cable are common installations, this would be no different.

We did it for hot tub install where the GFI disco was within sight but no conduit visible as we piped it from behind in a storage closet. Line in from panel, load back through same pipe back through panel then underground to final terminations at tub. Home owner didn't want to see the raceway but he had no choice on the disconnect
