How to install the wires for home decoration?

It is suggested to choose hard wire, that is, BV plastic copper wire, and BVV wire or ZRBV wire can be selected if conditions permit; "Acceptance Standard for Electrical Engineering of Civil Buildings" requires that indoor wiring of residential buildings should use hard single plastic copper wire, that is, BV wire;

The insulation thickness of hard wire is thicker than that of soft wire, and the mechanical strength and aging resistance of hard wire are much better than that of soft wire, so its safety performance is higher. The biggest disadvantage of hard wire is that it is difficult to construct and the labor cost will be higher than that of soft wire. In addition, it is not suitable for flexible connection.

Flexible cord, because of its low mechanical strength, is not suitable for use in the concealed pipe-threading part, and it is easy to break the wire. It is also not recommended for home decoration. In addition, it has poor aging resistance and is not safe to use for many years. Flexible packaging is suitable for places that need flexible cord connection, such as making a patch panel or connecting a light bulb temporarily, and it is best to use flexible cord; You can find this phenomenon from the wiring board we bought;

In addition, the soft wire construction is particularly convenient, because its wires are soft, easy to wire and connect, and the labor cost is lower than that of hard wire;

Selection of wire diameter for home improvement;

Lighting 2.5 square meters;

Ordinary socket 2.5 square meters;

Cabinet air conditioner 4 square meters;

The kitchen and bathroom are both 4 square meters.

Usually the live wire is red, the neutral wire is blue and the ground wire is yellow-green. In the wiring process, we must follow the "live wire incoming switch, zero wire incoming head" and "left zero and right fire grounding".

The total cross-sectional area of the wires in the pipe should be less than 40% of the cross-sectional area of the protective pipe. For example, at most four wires with a square of 2.5 should pass through 20 pipes.

Extended data:

Wire refers to the wire that transmits electric energy. There are bare wires, electromagnetic wires and insulated wires. Bare wires have no insulation, including copper-aluminum flat wires, overhead stranded wires and various profiles (such as special-shaped wires, buses, copper bars, aluminum bars, etc.). ). Mainly used for outdoor overhead and indoor buses and switch boxes. Electromagnetic wire is an insulated wire that generates a magnetic field or induces a current in the magnetic field after being electrified.

It is mainly used for windings of related electromagnetic equipment such as motors and transformers. Its conductor is mainly copper wire, with thin insulation layer and good electrical and mechanical properties, as well as heat resistance, moisture resistance and solvent resistance. Different characteristics can be obtained by selecting different insulating materials.
