Subpanel wire size

[rinconnick]

I want to run a subpanel to my garage. It is about 220 feet from my house.
What size wire should I run with a 100 amp breaker in my house breaker box?

First, what is it you are running?

I will be running an Arc welder, compressor with 5hp motor, refrigerator and general lights and garage doors.

I use this voltage-drop calculator...

Sounds like 3% max is recommended for feeders in the USA.

Because of the distance, I would probably go for #1/0 or #2/0 aluminum in a cable or conduit. Can go smaller if you're stringing up tri-plex overhead on poles.
