1. When the electrical box is only used for electrical box lighting or small power, the incoming line is less than 10 square meters, and the switch digit is less than 20, the switch width is added 20MM on each side, which is the width of the electrical box, the switch height is added 40MM, and the switch depth is added 10MM.

3. When the electrical box is only used for electrical box lighting or small power, and the incoming line is less than 10 square meters, if the incoming line switch needs a single row, the switch width on each side is 20MM, which is the width of the electrical box, the switch height is added to the wire switch 40MM, and the switch depth is added to the maximum depth 10mm.

4. When the power box is a power box or a power lighting box, the algorithm is basically the same as above. However, when the incoming line is greater than 10 square meters, the bending radius of the incoming line should be considered, and enough space should be left for the first-stage terminal to enter the line. When the switches are arranged in two rows, the wiring of the switches should be considered.

Of course, if the size of the electric box is not determined, it is necessary to consider the actual installation, the actual wiring diagram and how to arrange the wiring of the first-level switch.

If all circuit breakers are determined by the number of bits (18mm bits), the PZ series distribution box has a fixed size, and if the circuit exceeds 80 bits, it can be determined by the Party in the drawing (text). Device control box identification The device comes with the device. The input cable is larger than 185mm2, and the output cable is larger than 2. Select the cabinet type as much as possible.

The inverter cabinet is best made of 800*600*2200. In addition, the cabinet should have an air intake at the bottom and an exhaust fan at the top. It is recommended to install it at the top. If they are installed on two sides, rows of cabinets of the same size can prevent fan ports from being blocked. The thickness of the steel plate should be 2mm, and there should be plastic groove wiring. Don't reduce the size of the cabinet just because there are fewer circuits. Rows can be ugly.
