For the curious: I'm drafting a workshop which includes structural as well as electrical, gas and a dust collection system. A table saw is going to be brought into the structure and I want to do a preliminary drawing in TurboCAD where I want electrical outlets located. I've never hooked up a 220 VAC outlet except for one time a long time ago for my electric dryer. I don't plan on opening that plug just to see how it's wired; so is this correct?
