I was looking for a code section on the co-mingling of wires. I have recently had a turn down for having #10 type NM and #12 type NM in the same junction box.I have never known for this to be a problem. Could someone please shed some light on this for me. Thanks
 
There is no such requirement. I would demand the inspector provide a code reference, or approve the installation.
 
Yea, he caught me off guard, and actually made me feel like I was the idiot. I am to talk with him this afternoon to get to the bottom of this. Thanks for your help.
 
I agree with Charlie and Sparky, however some inspection departments get concerned that somehow the #12 conductors will get fused @ 30amps, as this is not their concern after they are done with inspections; I am agreeing with the above posts.

All grouning conductors should be tied together if they are not.

I've heard about you co-minglers of wiring. . Friends don't let friends co-mingle wiring ! . And I have would NEVER allow one of my kids to get into that co-mingling lifestyle. . It usually leads to uncontrolled games of twister and other debased fun which I forbid my kids to do out of jealousy because I'm no longer allowed to do those kinds of things myself [it's the stupid married thingy that ruins everything].

For your problem and situation, you'll need to find out if you have a "legally established easement or right-of-way" located with that junction box [90.2(B)(5)b]. . If you don't have that, then I would suggest that you think about leasing the junction box to "the electric utility for the purpose of communications, metering," etc [90.2(B)(5)c].

Unfortunately if you have to go the leasing route, the utility will probably demand that you remove all of your wires because they'll need the room for their stuff.

Hope I was of some help !

Remind the inspector of voltage drop issues. What do you do if you upsize to #10 for VD---How would you drop down the wire size? or would he expect you to continue the #10 for the entire circuit.

Hey-- ask him about the co mingling in a panel box-- Is that illegal also?
 
Sometimes i wonder where they found these kind of inspectors.Dont most states make them pass a test ?This inspector needs to find a new line of work.Like the rest i am waiting to here how this works out.

We do realize there are many good inspectors out there and there are just as many hack inspectors as there are hack electricians.

Most of the ec here take more shots at other ec's than the do at inspectors.

It is good that you don't take it personally because it is obvious that you and many others at this forum know a great deal and those comments are not meant for you.

Hey guys that is what we are stuck with,unreasonable inspectors and also hack electricians. Just wondering what there are most of. That may be a good question.

I hope I don't qualify for both. (smile)

Oh, does this apply in the service panel too?
