How to distinguish the gree air conditioning in a few phase electricity
Consisting of two phase thread called two phase power supply power supply circuit way, referred to as "two phase electric, the voltage of 380 volts. Is in a three-phase electric wire a zero line, referred to as "three phase four wire. Is 380 v.
See the power cord a few root, 3 thread is phase 2 of fire (1 1 1 ground zero), 4 wire is 3 phase electric (380 v, 3 fire 1 zero). Family is the single phase electric power supply, ac 220 v, most of the air conditioning is designed by the voltage (electric wires are a total of three line and zero line and ground). Mainly 3, 5 horses ark, a three-phase power supply, more units. If family use, buy the time to be clear, three-phase power supply is not working. To change all the electricity, the 380 v.
