D. Five Essentials of Rows of Wires When decorating a dark wire, you need to grasp the following five points:
—— Before construction, fully consider the electrical and lighting equipment required for each functional area, and use this as a basis to roughly calculate the cross-sectional area of ​​the corresponding wire for each road. High-quality copper core sheathed cables and concealed junction boxes should be used as far as possible to avoid aging and breaking, resulting in difficulty in panel installation.
- Draw the distribution diagrams of various residential circuits, and set the coordinates and heights of various lamps, switches, sockets, and distribution boards to determine the alignment of the routes and branches. The wires are best chosen in different colors in order to identify different circuits. |.cn (63639032)
- It is best to lay the power cord after it is put through the flame retardant pipe. In the ceiling of flammable structures, fire-retardant pipe must be added, and a power switch should be provided outside the ceiling to cut off the power supply when necessary. All wire connections should be inside the junction box.
- The total capacity of the indoor lines should not exceed 3000 watts per minute, and the load current of each single-phase circuit should not exceed 15 amps. Air conditioners and other large household appliances should set up special lines.
——The installation height of the switch is generally 1,200-13,050 mm from the ground, the height of the socket is generally 200-300 mm, and the height of the switchboard is preferably 1800-2000 mm.
