Wire for 50A 220V Service - 110' run

That aluminum wire,,,, would be a good wire to use,,,,,,, like if you had a small garden & used it for the wire when you have a row or two of running butter beans to string up.

No answer, so I guess it was 3 or 4 conductor wire.

I said I would probably go for it if i already had the wire. Not telling you to.

OK. The vote is in. 237,891 say it's a bad idea. One person said go for it, but he doesn't like me.
So back to the drawing board. I just happened to have that wire on hand.

Use copper. Avoid splicing.

I thought that the main problem with aluminum wire, at least back in the 70s when they used it in houses, was that it expanded under the screws holding it to receptacles and caused the screws to back out, creating a gap and resulting heat and fires. their cure was to use a piece of copper wire at the receptacle and hooked that up to the main run of aluminum.
copper clad aluminum is still legal AFAIK.

Bad idea!

And these are 3- or 4-conductor wires?

Years ago I had a home wired with aluminum wire and it was a nightmare. Its a wonder it did not burn down.

I have used the underground splice kits for that type of wire several times and always thought I did a good job of sealing it up. However, it always came back to bite me. If any moisture ever gets in there, the al will oxidize and fall to pieces. All that being said, if that is what I had, I would go for it considering the price of wire now.
