Description: A split-phase or single-phase three-wire system is a type of single-phase electric power distribution. It is the AC equivalent of the original Edison three-wire direct-current system. Its primary advantage is that it saves conductor material over a single-ended single-phase system, while only requiring a single phase on the supply side of the distribution transformer.The two 120 V AC lines are supplied to the premises from a transformer with a 240 V AC secondary winding which has a center tap connected to ground. The system neutral conductor is connected to ground at the transformer center tap. This results in two 120 V AC line voltages which are out of phase by 180 degrees with each other. When required, 240 V AC can be obtained by connecting the load between the two 120 V AC lines.
