I have run wire, 10/3 from a subpanel, for wiring for shop and was going to use 220 volt wiring for my tablesaw which is a 2 hp motor. I was going to have an outlet for the tablesaw and wanted to know if code allows for more than one 220 outlet as long as the load does not exceed the total amperage for the circuit? I want to run the tablesaw with my 1 hp dust collector.

Short answer, no problem if the receptacles match the ampacity of the circuit.
Your problem is going to be that your table saw and dust collector will have 6-15 or 6-20 plugs on them and the combo 6-20 receptacle would work for both but you can't put that on a 30a circuit.
There are 2 fixes, you could put in a small 4 slot sub panel and run 2 circuits at 15 or 20 amps. You might even take a 120 off of those since you have a 10/3 with a neutral. Using this receptacle.

The less legal solution is just to put a 6-30 plug on the tools and use 6-30 receptacles but that probably breaks a number of rules.
Thanks Greg, another question.
Can I change out the plugs to match a suitable receptacle? Thanks for your reply.
Once you price out 6-30 plugs and receptacles, the other solution may seem attractice to you. Both the table saw and the dust collector are motor loads so I doubt the 30a breaker is a problem but putting a 30a plug on it does violate the listing of the product.
I still think splitting this out to two 15 or 20 amp circuits is a better way to go.
