What should be paid attention to when laying wires indoors? 1. Comprehensively understand the capacity of home appliances. Before wiring, consider the amount of wires and the port specifications of wires according to the total number of home appliances and the subsequent addition of home appliances. High power appliances such as refrigerators, ovens and air conditioners need to use a separate circuit. Household appliances need to be constantly added and updated, and the power will also be constantly strengthened. When wiring, not only

The design of external cable lines uses cables to transmit electric energy, which is less damaged by external wind, rain, hail and human activities. Both material and installation costs are high, because the efficiency of transmitting electric energy with metal materials of the same cross-section for heat dissipation is not as high as that of overhead lines. It does not occupy land and is conducive to beautiful environment. Cable structure According to different structures and functions, cables can be divided into power cables, control cables and telephone cables
