How is the circuit modification considered qualified?

Hydropower renovation is a hidden project and it is a very important part of the renovation process, especially the circuit transformation. If the decoration is not good, it will easily bring serious impact on the future of home life. Therefore, for the sake of a safe life, it must be To do a good job of acceptance, how can we know whether or not the circuit transformation is qualified?

First, whether the acceptance circuit material is qualified

Check whether the specifications of the original materials such as wire rods and pipes are the same. Purchase all wires, telephone lines, television lines, and network lines must meet the national testing standards to prevent product non-conformity.

Second, whether the appearance of the acceptance circuit meets the requirements

Check that the installation location, routing, etc. meet your requirements, and make sure that all outlets are in the correct position. Whether the position of switches, cassettes, etc. meet the requirements of symmetry and consistency.

Third, acceptance circuit construction

The family usually uses AC power. Some construction teams directly store all the wires together for the convenience of construction. Power lines, network cables, telephone lines, etc. are all placed in the same bottom so that the lines can be disturbed and the signals are not affected. stable. It will also lay a hidden danger for home fires. The strong and weak electricity should be routed separately. It is strictly forbidden to share one pipe and one bottom box for strong and weak electricity. The parallel distance of strong electricity lines should not be less than 3cm, preferably 50cm, and the crossing must be a right angle.

Fourth, check whether the wires are sleeved

Some irresponsible construction parties will directly bury electric wires in the wall during construction. The wires are not covered with insulating tubes, and the wire connectors are directly exposed. This can easily cause safety hazards and is a typical phenomenon of cutting corners. The specification of the laying of wires is clear and there must be protection of the insulation sleeve outside the wires. The joints cannot be exposed. Pay special attention to this when checking.

Fifth, check whether the outlet wire is installed arbitrarily

Many families use slotting and dark pipe laying for aesthetic reasons. When wiring, we must follow the "fire line into the switch, zero line into the lamp" principle, but also set leakage protection device on the socket.
