Generally, there is only one fire wire and one neutral wire for single-phase power, and the single-phase power is for home use. Then, three fire lines or three fire lines are the three-phase electricity, and three-phase electricity is the industrial electricity.

2. When we install the air switch, we must turn the word of the air switch upwards. The area above the word should enter the line, and the place below the word should have the line.

We call a FireWire 1P, this applies to 220V low-power electrical appliances; a FireWire a neutral line called 2P, suitable for 220V motor; then the three FireWire is 3P, for 380V appliances .

3, under normal circumstances, the air switch and distribution box can be used to connect. If there is no distribution box, you can use a fixed air switch slot instead. Fix the card slot to the wall or wood and install the air switch on the card slot.
