When decorating, many people make a lot of misunderstandings because they don't know all kinds of materials very well. Take
the wire as an example, most people think that the thicker the wire, the safer it is, even if it is more expensive. The editor of Pearl River Cable also thought so, but some time ago, a friend's house was decorated with 4 square wires. After seeing it, the old electrician said he was stupid.
The square of a wire is its cross-sectional area. There is a rule for the PVC pipes used to install wires, that is, the total area of the wires cannot exceed 40% of the pipes, otherwise it will affect the normal use. Generally, the general PVC pipe can hold six 2.5 square wires. If you install 4 square wires, you can only install 3 wires. In this case, the number of sockets will not be used later.
General household appliances are completely satisfied with 2.5 square wires, and there is no need to install all 4 square wires. The price is expensive and there is no practical use, which is too wasteful. Pearl River Cable recommends that you choose the square of the wire according to the electrical appliances in your home, so that it will be more reasonable.
Generally, a 1.5 square wire is enough for a switch wire. Conventionally, all electrical appliances use a 2.5 square wire. For high-power electrical appliances such as air harmonics and electric water heaters, 4 square wires can be used.
As long as you choose the square number of wires according to different areas and appliances, you can save money and be useful. In addition, for the sake of safety, it is better to install a leakage switch in the place of the wire switch.
The wires installed by developers are generally 2.5 square meters. You only need to modify it a little according to your own practical application needs.
