What needs to happen in here is for people to realize that talk about three phase delta and wye circuits may be interesting, but it's noise in here. We DIY'ers recognize that there is three phase power available for equipment that uses it, but it's not something that we need to know about, interesting though it may be. And, while I appreciate the input from the professional electricians in here, we all know that our brains are excellent housekeepers and that what we don't use will soon be thrown out to make room for stuff we will use. Three phase power, and how to wire it is something my brain is just itching to throw out. It needs the space for stuff it will use, like how to fix a fridge or spread drywall joint compound smoother.
