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.

50 Amp RV is 4 wire split phase (2 120 hots + neutral + gnd). 30 amp RV is 3 wires single phase (120V hot + neutral + GND). So the cost for 50 amp is quite a bit more. You also need to be careful to make sure it is legal/safe for you to add more circuits to your panel, it may already be maxed out. You need to consider if you have any open space in your neutral and ground bus bars for heavy wire too.
I wouldn't do any heavier than #6 CU because chances are the 30A breaker and socket lugs won't accept anything heavier anyway.
I ran a 50/30/20A RV panel with integral breakers for my house but that worked out for me because I replaced an old hot tub junction box that already had 50A/240V run to it with #4 CU.
