Wire gauge for a 200 ft run on 30 amps or 50 amps?

3% Max Voltage drop for that 200' run

Otherwise you will have Low Voltage any time the supply voltage drops below 115V


50A #1AWG
30A #3AWG

Do NOT scrimp on the wire size...........

Agree with not scrimping on the wire but might get sticker shock when you get the prices for this..

#1 AWG copper single strand is going for around $1.90 per ft

For 50A 240/120 you will need 3 runs of #1 (two HOT and 1 Neutral) and 1 run of #3 (for ground)..

I suspect by the time you buy wire, conduit and other needed materials you will be north of $2,500 and if not doing the work trenching and installing conduit that labor cost could easily get you well above $3500..

I would suggest, finding a closer spot nearer to your electrical source that could knock off 100 ft of wire which would get your cost a bit more reasonable..

Alternately, nothing says you HAVE to breaker it for 50A, you could run 240/120 but use a lower amperage breaker like a 30A double instead of 50A double. That would allow you to use lighter ga wire..
