What are the requirements for wire and cable installation? Let's find out together

Only when the wires and cables are installed in place can the safety of electricity at home be basically guaranteed. However, if the installation of wires and cables does not meet standards, it can easily lead to some electrical safety hazards. So what are the requirements for wire and cable installation?

Wire and cable installation requirements 1: Wires must be divided into strong and weak ones.

Wires and cables are divided into strong current and weak current. However, during the actual cable installation process, some construction teams directly put all the wires together for the convenience of construction. The consequence of this is that the lines will be interfered with, resulting in signal instability and even serious fire hazards. Therefore, the state requires that different types of wires be separated when socketed, and co-management should be avoided as much as possible.

Wire and cable installation requirement 2: Cabin where wires are installed concealed

The installation of wires and cables can be divided into exposed installation and concealed installation. Different installation situations have different cable installation methods. However, in order to cut corners, some irresponsible construction workers bury the wires directly into the wall when installing the cables. As a result, the cables cannot prevent external damage, resulting in short circuits when the cables are used, and even fire and other safety hazards. Therefore, the state requires that cables should be concealed before installation.

Wire and cable installation requirement 3: Wiring cannot be repeated.

Generally speaking, the thread should be made into a "living thread". However, in actual cable installation and construction, some construction workers use one line for one pipeline, so there are many pipelines buried in the wall, which also brings trouble to future maintenance. Therefore, wires in the same direction are placed in one pipe without exceeding 40% of the pipe capacity.

Wire and cable installation requirements 4: The power cord should use copper wire.

As we all know, wires and cables are divided into copper wires and aluminum wires. If you look at the price alone, the price of copper wire is generally 3.5 times that of aluminum wire, and the price of aluminum wire is much cheaper than copper wire. So in some places some people want to use aluminum wire instead. However, because aluminum core wires are prone to oxidation, they often catch fire at the joints and are not very safe to use. Therefore, the state requires the use of copper wires instead of aluminum wires for cable installation.

Wire and cable installation requirement 5: Install the socket carefully.

Generally, sockets have three types of wires, live wire, neutral wire, and ground wire, especially live wire and neutral wire. The socket mainly relies on these two wires to form a complete circuit so that the socket can work properly. But if the socket does not have a neutral wire, everyone will use the one without "power" as the neutral wire. In fact, there are still some safety risks. Therefore, the state requires caution when installing cable sockets, such as checking the circuit first.
