Does anyone else have problems when they hear people call 120/240 1p "split phase" or even "2 phase"?
Yikes it sets my teeth on edge.
The problem is even Wikipedia and a few panel manufacturers use the term split phase in their documentation. Split phase is one way to wire a motor and there is only one phase in your household panel with 2 ungrounded conductors derived from one 240v secondary that just happens to have a grounded center tap. It is simply single phase, nothing else.
I know it was not on any streetcars, it was n a house of worship in Center City. A sub-basement, way down below grade, and that made it scarier. Heck, if there was any issue, noone would have found us.
I found this dictionary , but it appears in need of some updating>>>
Phase. In wave motion, oscillating motion, simple harmonic motion, or similar periodic phenomena, the interval of time passed from the time the moving particle moved through the middle point of its course to the instant when the phase is to be stated
