Running new a/c line


The wire would have to follow this path:

-from the panel into the attic
-down an interior wall inside the garage
-go through the block wall
-run down conduit along the wall 5 or 6 feet to the disconnect

What is the best/proper way to run the wire? I was going to run the whole line in NM wire, but I am not sure if I can sleeve NM cable that far. I would like to keep it all in one run, but I can add a junction box to either the outside or inside of the garage and run THHN or THWN wire the rest of the way to the disconnect.

Technically(code wise) NM cannot be installed in wet loctions even when it is sleeved. UF cable can be sleeved and used in wet locations.

Depending upon your conductor sizes, your junction box plan may be the best.

For sleeving I would recommmend using liquidtight non-metallic flexible conduit.
