Be careful of wire installation errors, safe use of electricity

Be careful of wire installation errors, safe use of electricity

Myth 1: Strong and weak condominium
Commonly used in our homes is AC power. Some construction teams directly store all the wires together for the convenience of construction. The power cables, network cables, telephone lines, etc. are all placed in the same bottom, so that the lines will be disturbed, resulting in interference. The signal is unstable. It will also lay a hidden danger for home fires. Strong and weak electricity should be separated separately. It is forbidden to share a tube and a bottom box with strong and weak electricity. The parallel spacing of strong electric lines should not be lower than 3cm, preferably 50cm, and the intersection must be at right angles.
 
Myth 2: Repeated wiring
Some builders use a single pipe for each wire in order to make the pipeline look clearer, so that a lot of pipes are buried inside the wall. It is difficult to find the location of the problem pipeline when repairing in the future, or it is necessary to destroy most of the structure of the wall and the ground to find the problem. In general, the line should be made "live" and placed in the same tube with no more than 40% of the line capacity. This is both economical and avoids the hassle of future maintenance.
 
Myth 3: The wires are buried without casing
Some irresponsible construction parties bury the wires directly into the wall during construction. The wires are not covered with insulating tubes, and the wire connectors are directly exposed. This is easy to cause safety hazards, which is a typical phenomenon of cutting corners. In the future life, the wires lack protection, are easily bitten by rats or receive external damage, and the wires are short-circuited. The laying rules of the wires are clear, the outside of the wires must be protected by an insulating sleeve, and the joints should not be exposed. Therefore, at the time of construction supervision, the owner must supervise whether the construction party is required to construct.
 
Myth 4: The socket wire is installed freely
The power leads must use a copper wire cross section. If you live in an old house, be sure to replace the original aluminum wire with a copper wire. Because the aluminum wire is easily oxidized, the joint is easy to catch fire. There have been surveys showing that the incidence of electrical fires in residential buildings using aluminum wires is several dozen times that of copper wires. In addition, many families use the method of slotted and buried pipe to make the appearance beautiful. The wiring must follow the principle of “fire line into the switch, zero line into the lamp head”, and also set the leakage protection device on the socket.
