Guys, Also do not forget the neutral sizing on a Scott (2phase) connection. Remember it is only 90 deg. out of rotation. Scott, where do you live ? I have seen some VERY WRONG utilities in PA using a single wire on rural connections years ago, utilizing a ground return path, which is EXTREMELY hazardous. I would hope they have all been changed by now. No, they can have a single energized (ungrounded) line, and a grounded line, but must have 2. You guys keep overlooking "Uglys", they used to have the schematic for old 2 phase Scott circuits, one reason is that a lineman used to have to connect it and 'splain it to pass his Class A test, I don't think anyone does this anymore.
