This three-phase four-wire design idea often causes the customer side voltage in the meter box to rise due to the broken zero line in the use process, resulting in household appliance burning accident. Therefore, most basic power supply stations adopt 220V meter box power supply mode.

[0003] However, in the use process, the 220V power supply meter box needs to solve the problem of three-phase switch, and the three wiring terminals of the total switch of the meter box need to be connected in parallel by short lines, and the zero line is connected by the way of connecting after crimping by the wire nose. Therefore, people use the wire to make a conductive ring to conduct the three-phase switch power supply side.
