Answer Posted / chuck rogers
The sum of any 2 phases is 440. This is a rough estimate as
several factors can play on the load side of the circuit.
Between any one wire (phase) and ground can be 207VAC to
277VAC (with no Load). It's that way because the electrons
said so . . . I talked to them last week.
