How to connect the three-phase electricity to the water heater

First: the connection mode is the same as that of the motor. Three pipes have six terminals. First, connect one end of three pipes together, that is, 2. After that, each of the three live wires is connected with an electric heating tube, that is, 1. End, this is ok.

The second type: electric heating tubes are W, U, V, 1. , and 2. Connect as shown in the figure, and then connect the three live wires to 1. , and it is possible.

Three-phase alternating current is a transmission form of electric energy, which is called three-phase electricity for short. Three-phase AC power supply consists of three AC potentials with the same frequency, equal amplitude and phase difference of120.

Three-phase alternating current has many uses, and most industrial alternating current electrical equipment, such as motors, adopts three-phase alternating current, which is commonly called three-phase four-wire system. In daily life, single-phase power supply is often used, which is also called lighting power consumption.

When lighting is powered by electricity, one of the three-phase electricity is used to supply power to electrical equipment, such as household appliances, and the other is the fourth line of three-phase four wires, that is, the zero line, which leads out from the neutral point of three-phase electricity.
