I'm wanting to add some 220 outlets in the garage to run my woodworking equipment, and I have a couple of questions. First, can I run one 220 circuit with approximately 4 plugins on it? Only 1 piece of equipment will ever be used at one time (or does this violate code? ). Also, I'm under the assumption that since it's in a garage (attached) even the 220 circuits must be GFCI. Do I have to install GFCI breakers in my subpanel, or is there such a thing as a GFCI plugin for 220? Thanks for your help.

Sure, 4- 240 volt receptacles can be on one circuit.

Code only requires 120 volt receptacles in a garage to be GFI protected.

However, having a 240 volt circuit in a garage for the purpose of a power tool would be a good idea, and the only way to do this would be to use a 2 pole 240 volt GFI circuit breaker.

Thanks! Now if you could help me understand one other thing. I've looked over the three tools that will be run on the 240 volt circuit (again, only one at a time) and the one with the largest draw is the table saw (3hp, 220V, 18A). With that in mind how do I figure out the proper sized breaker and wire to complete this circuit? Thanks again.

Branch circuit size is rated 125% of the running load of a motor, 18 x 1.25=22.5 amps, so the wire must be at least #10 with a 25 amp breaker. A 30 amp breaker is allowed also.
