Residential electric service in the United States (120/240 VAC) is sometimes called two-phase service but this is NOT correct.wo-phase service is an obsolete style of electrical power distribution where two phases are provided that are 90Â° out of phase with each other.
The mathematical formula for a single-phase service is to divide the ungrounded conductor voltage line to line by 2 to arrive at the one line to neutral voltage (240/2 =120). A three-phase system uses 1.732 (square root of 3) as the divider (480/1.732 = 277.14). It is important to note that single-phase power is available from any three-phase system. Most single-phase appliances, motors and HVAC systems are rated at 208/230/240 volts.
