Will 100 amp service run a welder?
you will never run out of power with 100 amp. also you dont need to unplug the welder when not in use it will not draw any amperage when not in use. i would run atleast 6-8 220v locations so that if you decide to remodel you can move your welder/comp any where.
Can you run a 100 amp sub panel off a 100 amp main panel?
You can run a 100 amp subpanel off a 100 amp main panel because the total can be up to twice the amperage of the box, meaning you could run a subpanel of up to 200 amps. What’s critical, though, is that the subpanel is safely and correctly connected to the main panel and that you don’t overload the service panel.
How far can ground rod be from panel?
The Code requires you to space rods at least 6 feet apart [250.53(B)]. However, this spacing is a minimum — and far from ideal. When using the typical 8-foot or 10-foot ground rod, you get the best results by spacing the rods at least 16 or 20 feet apart, respectively.

60 amps would be enough, as long as your building is well insulated and your not planing on running a monster sized welder or compressor. My father has a 20×20 with 220v welder, electric heat, compressor and a bunch of woodworking tools easily running off a 60 amp panel.
How do you hook up a 100 amp subpanel to a garage?
Use 1 1/4-inch PVC conduit for a 100-amp sub panel or 1-inch PVC conduit if the sub panel is 50 amps or less. Run the conduit from the garage to the main panel box. If concrete has not been poured in the garage, run conduit down into the ground on the inside of the garage.
What size breaker do I need for garage?
