Electricity is an indispensable energy source in daily life, but with the popularization of electrified equipment, electricity consumption is no longer limited to household life, but also involves multiple places such as industrial production, agriculture, and commerce. Wherever electricity is needed, stainless steel meter boxes are indispensable distribution equipment. Stainless steel meter boxes are a better guarantee for the safety of our national power grid and public electricity consumption.
Today, we will mainly talk about the precautions for incoming and outgoing lines when installing stainless steel meter boxes. The following are the main contents:
1. The insulated copper wire of each meter wiring in the stainless steel distribution box should not be less than 4mm2, and the RS485 circuit wire should not be less than 0.5mm2.
2. Insulated flame-retardant wires should be used inside the box, and the color code should be: yellow green red for the phase wire; The zero line is black; The PE line is a yellow green dual color line.
3. The creepage distance of the incoming unit is greater than 12mm, the electrical spacing is greater than 10mm, and the creepage distance of the outgoing unit is greater than 8mm.
