What Cables Are Used in The House?

Aug 04, 2022

Before the renovation, the water and electricity renovation must be carried out. In the water and electricity decoration, mainly engaged in the design of lighting circuits at home. Today, depending on the size of the cables used in the designed household circuits.


1. Select the thickness and type of cables required for home decoration


The lighting circuit used in this household generally uses BV single-core hard copper wire. In order to be able to choose the size of the transmission line, the transmission line must be preserved under the premise of ensuring safety and stability. After all, home renovations cost a lot. Therefore, be sure to carefully measure the cost of each order. When decorating, the main basis for my choice of wires is to clarify the safe disconnection amount of the wires. The amount of safe disconnection of wires must first be determined based on predictive analysis of the load used by household lighting fixtures.


Therefore, it is possible that the load of the household is based on the heating standard and the selection of electrical wiring. If the raw material of the wire is correct, the selection of the cross-sectional area of the cable is the first problem to be considered. We all know that the greater the conductivity of the raw material of the transmission line, the more the cross-section, the greater the safety disconnection level of the transmission line. According to my general work experience, it is also related to the insulation layer material. The connection method and the working temperature of the cable. For example, if the common 2.5mm² BV hard copper wire is mounted on the surface, the cut-off volume for long-term continuous safe operation is 32 ampere. If the construction is through pipes, insert the two cables into the PVC pipes. As of the total flow, only 24 current flows can be achieved. If you wear three cables, it will drop to 21 amperage. If you wear four cables, there are only 19 currents. Most of their trims use PVC pipes, so when assembling wiring at home, choose 10mm2 BV hard copper wire and 2.5mm2 hard copper wire for lighting circuits. , the power socket should use 4mm2 hard copper wire, while the air conditioner uses 6mm2 BV hard copper wire.


2. Choose the color of the wire when decorating the design


When decorating, people focus on ignoring the color of the wires. In order to reduce costs, some water and electricity decoration workers will apply cables that do not meet the requirements of indoor wiring colors. Use the bright red power line as the live power line. Wire connectors are used, which is also not allowed. In addition to convenient construction and installation, the effect of specific wire colors in the decorative design process will also give us great convenience in maintaining the lines. It can reduce misjudgment and thus reduce the occurrence of route accidents. my country stipulates the use of light colors, one of three colors, green and red. Use a light-colored tie line as the working neutral line, such as blue line and green two-color line to protect the line.
