208/120v to building, 120/240 in apartments - please explain
My apartment house has 120/208v Wye connected (4 wire plus ground) service from the utility. Apartments have 120/240 service. we can easily measure the 120v from phase to neutral - and I can comprehend the math that shows 208v between a phase and the imaginary point directly opposite the phase.
i can't see how this provides the 240v part of 120/240 to the apartments.
i am certain this has been addressed 100 times before, and would appreciate somebody helping this dummy for the 101'st time.
