Generally speaking, there are many loops for the number of electricity meter positions. An electricity meter measures the electricity consumption of a household and the incoming and outgoing line switches, wires and electrical appliances form a small loop. So how many meters, how many circuits, and how many users determine how many meter boxes are used.
The size of the switch and the number of square wires used in this circuit are all based on the maximum power consumption. Therefore, when we communicate with customers, we always ask them what projects are used to provide solutions.
