We are gettin ready to start construction on a new house and I want to budget for 220 volt installation in the basement for three power tools.
My question is, in a 220v circuit, does code allow only one outlet per breaker and circuit? If so, can anyone give me the rational since 115v curcuits allow multiple outlets and allow the circuit breaker to prevent overload.
And finally can anyone give me a ballpark number for what it should cost to get 22ov to my tablesaw, bandsaw and planner?
Thanks guys,
Chris

taking a wild shot here......
i was told that i could only use 1 outlet with 220 if i wanted to adapt a 20 amp 3 wire for 220.....otherwise i would have had to run new wire for multiple outlets.
is that what you are refering to? or something like that
Dunno about code. I thought that you could run multiple outets just like 110v, as long as your load didn't exceed the breaker rating. I know that I have 2-220 outlets in my basement and the electrician ran homeruns for each of them.
As far as wiring, each one is just a 2-pole 20 amp breaker and 12/2 wire to each single receptacle. No more costly than running 110 ('cept for the breaker).
You can run multiple 240 outlets on one 240 circuit. If, instead you have 220, don't run anything on it. Instead call the power company and have it fixed.
There is a technical gotcha, however.
Any load with a nameplate data that indicated that it draws more than 50% of the circuit rating requires a dedicated circuit. There is a good chance that one, if not all 3 of those loads draw more than 50%.
Now you know, and I know, that you are only going to be using one at a time. However, the code does not reconize that.
So if the inspector questions it say that you only have the table saw, but want to be able to move it around.
The other approach would be to leave the table saw, band saw, and planer far from the job site until after the electrical is signed off. The inspector inspects conduit, wires, and receptacles. What you plug into those receptacles isn't an issue if it isn't there yet.
