What Size Wire 30amp
I would like to put a 30 amp RV plug on my garage. The service pole is about 80 feet from the garage. I was wondering was size wire I will need to support 30 amp service.

I would use #8 aluminum and save a few bucks over #10 copper.
Aluminum wire has had expansion/contraction issues in the past. there have been reports of loose connections due to it. and even some fires from loose connections that build up heat. I have aluminum service coming into my house and I need to check the connections regularly for tightness.
Best stick to copper.
