That was my thought as well but I'm beginning to wonder after reading thru all the post again. That was why I said in my earlier post that the OP could use the #10 CU at each end as long as he had suitable AL/CU connectors.
Sounds like you're on the right page now.
Yea thanks Im on the right page. Pretty much what I was saying from the OP and post #3 though. The fact that the two different types of wire (aluminum and copper) being in the same raceway is what got me thinking from the beginning. In residential I often have had to connect aluminum to copper with junction boxes using alumicons then to new devices, or for larger conductors like the range I've gone from #8 copper in new panel to a j box in crawl that tied to #6 aluminum that went to range box and never thought twice about it very common. The fact this involved different conductors in EMT is what I was thinking about. Some of the older romex Ive demoed had #6 aluminum conductors wrapped in strands of copper I had to twist that was the ground. But again the raceway is what I was concerned with.
Absolutely, yes.
I lump it in there as well, but there will be that occasional inspector that will call it out anyway, then you either need to comply or convince inspector otherwiseIsnt there a code section that arguable covers such "other cables"? I cant remember where that is.
Besides I lump this in the "technicalities that no one cares about" category, like using a PVC TA in a myers hub.
