3 phase power on the other hand uses three active wires, 120 degrees apart, and one neutral wire. It can deliver up to 415 volts. In a 3 phase system, the three active wires each feed into the neutral wire in turn. So power is delivered in three separate waves in sequence, but with some degree of overlap. This means the delivery of power never completely falls to zero.

Supply is also more reliable and efficient as the wires can compensate for each other in a failure situation. So, if one wire fails, the other two can continue supplying power to some extent.

3 Phase generators are usually required for heavier duty commercial, industrial and off-grid applications in contrast to their often smaller & more portable single phase counterparts.
