I am adding a subpanel in my basement. I need to run the service line across a finished ceiling to a utility room where the subpanel be located. I have 1 – 1 – 1 – 3 aluminum wire for the service line.
My question is, Does this wire have to be run through conduit or can it lay acrossed the drywalled ceiling over the 20 foot run?
Also, is there anything that says that the running it in conduit is prohibited? In case I choose to do it to be certain.
