Renovation is not a small problem, sloppy. In the process of decoration, hydropower is a top priority. Many owners don't know much about this piece. Xiaobian this time sorts out the small knowledge about circuit construction quality and acceptance to the owners. Electrical construction quality and acceptance criteria First, electrical construction process requirements and standards: 1. Before installing complex circuits, a concise circuit diagram should be drawn up according to customer requirements, and the direction of the line should be indicated. After the project is finished, the concise road map should be submitted to the user for future maintenance. 2. All wires are not allowed to have joints in the wall, and the pipes (PVC pipes or snake skin pipes) are buried in the wall. The wire shall go in the wall, and the insulation of the wire shall not be damaged, and the short circuit or open circuit shall be avoided. Copper wire is strictly prohibited in the fuse box. 3. All wire boxes, switches, sockets and lamps must be installed firmly and correctly. The switch box must have a wired box inside the wall of the socket. Generally, the switch is about 1200mm from the ground, and the ground socket is about 300mm. The fire line must be switched on. 4. The power cable generally uses 2.5mm copper wire. Responsible for modifying the power switch, telephone socket, etc., but not responsible for TV video line modification. Should be revised by a professional. 5, the wire line laying must use PVC wire trough line pipe. 6. The electrician should install the lamps, switches and panels after other renovations are completed. Before this, after the circuit is inspected, the insulation tape should be used to complete the installation. 7. All electrician construction should comply with relevant state regulations. Wiring diagram VC line wiring should pay attention to the following provisions: 1. pipeline: 1 PVC pipe must be elasticized, slotted with a cutter, and the depth of the groove is 1-1.5 cm mortar protective layer. 2 If the PVC pipe floor is not slotted, firstly slide the ground straight line and fix the pipe along the ink line. 3 86 The distance between the cassettes should be between 0.8-1 cm. The kitchen and bathroom walls should be covered with brick thickness. 2.

It is forbidden to take a tube with strong or weak electricity. 2 The wire must be separated: red is the fire line, blue or green is the zero line, the two colors are the ground line, and the white is the control line. 3 The wire should not be less than 15 cm in the switch box or socket box. It should be wound into a ring and placed at the bottom of the box. The wire is wrapped and covered with a protective film. 4 The ground wire and the common wire should pass through the box without cutting, and there should be some room for it. 5 Air-conditioning, water heaters, kitchens, Yuba and other high-power appliances, need to take the line that can be loaded. 6 The wire connector inside the cassette must be wrapped with a waterproof tape first, and the outside is wrapped with an insulating tape. 7 Performed with the electrical load reference standard. 8 The length of wire retention in the distribution box is not less than the half-length of the distribution box. 9 The bottom margin of the distribution box should be no less than 1.5 meters.

The same indoor switch must be on the same horizontal plane and arranged in the most common and rarely used order. △ The switch socket is not allowed to be pressed on the tile waist line and tile. 4. Installation regulations for lamps: 1 Each single branch circuit is not allowed to exceed 25 lamp heads, except for lanterns and lanterns. Under normal circumstances, it is strictly prohibited to exceed 10A. 2 Where the screw light must be the center point connected to the phase line, the zero line is connected to the screw terminal. 3 The mirror headlights are generally installed at a distance of about 1.8 meters from the ground, but must communicate well with the customer. 6 The embedded luminaires are fixed on the special cabinet frame, and the wires should have room in the lamp box for easy maintenance and disassembly. 7 The luminaire and the frame should be placed close to the light barrier and completely cover the light hole. No exposure is allowed. 8 The frame of the rectangular luminaire should be parallel to the decorative line of the top grid, and the deviation is ≤5mm. 9 The T4-shaped fluorescent tubes in the light trough should not be too long, causing a shadow between light and light. 5. Circuit switches and sockets, electricians and owners carefully determine the chalk mark, the socket should not be less, pay attention to the sliding door cover, the switch should be convenient and reasonable, the wire can not be directly buried in the wall. 6. After re-arranging the modified circuit, it is necessary to use the circuit layout diagram to distinguish the direction of the strong and weak electricity. 7. After the electric pipeline is laid, the circuit is shaken by a megohmmeter. Second, circuit acceptance (1) All kinds of electrical material brands should meet the design and owner requirements. (2) The total and branch leakage protectors shall be within the safe load range.
