220v circuit in garage

["Larry Spector" <lis@visix.com>]

I'm having a new home built, and I'd like to get it wired with 220v 
to the garage. Any recommendations as to the amperage I should allow 
for? I'm expecting to eventually use the circuit for a compressor, 
a small welder and a space heater. No, I don't own these toys yet, 
I'm just trying to plan ahead.

Thanks for your help.
