Circuits are the most problematic in hydropower construction, and there are two main reasons. First, electricians do not have related certificates at all, and they have not been subjected to formal electrician operation and learning, resulting in non-standard construction; the other is to violate the rules of circuit construction in order to cut down on materials and obtain more benefits. . The owner must pay attention to the uniform color of electrical wires in the circuit construction. This is the most problematic. The second is the damage of the cassette and the failure to lock the mother. Finally, there is suspicion that the layout is irrational and there is a detour to increase the length.
Editor's note: The correct construction method for the protection of the lighting line on the ceiling is to pass the lighting wire through the yellow wax tube and then into the shallow groove on the ceiling. In this photo, it is a wrong practice for the top lighting line electrician to wrap in insulating tape, and the insulating tape becomes sticky and then softens after a long time. It is not safe to bury it in the wall, and it does not protect the wire at all.
Editor's note: The wires embedded in the wall must be protected by pipes, and the cassettes for installing the panels must be intact and secure in order to protect the wires inside. In the picture, there is a line without wires, and the electrician breaks the cassette when it is threaded. Readers must carefully check if they are doing decoration. Do not allow such a cassette to be installed in your home.
