Electricity is one of the most important energy sources for our daily homes. Our lives cannot be separated from electricity. Doing a good job in the acceptance of electricians and ensuring the construction quality of electricians will help us have a stable power supply and prevent many hidden safety hazards.
Electrician acceptance details: 1. Electricians should be familiar with the circuit construction drawings or the owner’s requirements before construction, and ensure that all electrical appliances, switches, telephones, TVs, and network sockets are located. 2. The switch and cassette positioning must be symmetrical and consistent in vertical and horizontal according to engineering requirements. 3. All wires, telephone wires, TV wires, and network wires must meet the national testing standards to prevent product failure. 4. Circuit slotting, routing, threading, inspection and testing. The wire joints are firm and not loose, and are tightened with double-layer insulating tape, and there are inspection ports at the joints. 5. Check whether the switches of all lamps are flexible, whether the socket panel is loose, and prevent conduction and leakage. 6. Each group of circuit loops is clear and reliable, and meets the electricity requirements. The live wires, neutral wires, and wires should be colored or clearly marked. 7. The owner is requested to check and sign without any problems and then use cement mortar to seal all the wire slots and cassettes to ensure the normal construction of the bricklayer.
Electrician acceptance specifications: 1. When carrying out various line shifting transformations, first determine the location of the line terminal socket, and mark the exact position and size on the wall, and then lead the same kind of socket nearby. The method of lead is: If the socket is on the upper part of the wall, slot vertically upward on the wall to the top of the wall to install the decorative corner line within the installation line; if it is on the lower part of the wall, slot vertically downward to the bottom of the skirting board. The depth of the groove is about 15 mm. Put the wires into the protective sleeve, lie in the wall groove, smooth them with cement mortar, and fix them in the wall. If the original socket is retained, reinstall it in the original position. If not, use bricks to fill the plug and smooth it with cement mortar. When installing the skirting board, the wires along the ground lie on the inner side of the bottom of the skirting board, and the wires along the top corners are hidden inside the decorative corner when installing the decorative wire. 2. Construction specifications for circuit renovation projects. The groove depth should be the same, and the groove line should be straight. The control line should be ejected on the wall first, and then use a marble machine to cut the wall and manually groove. Wire protection sleeves must be added during line installation. The sleeve connection should be tight and smooth. The inner side of the corner should be cut at the right-angle corner, and the arc-shaped interface should be cut on one side of the cut, and then bend for installation. After the wire is installed in the casing, the wire fixing clip should be used to fix it in the wall and the wall first, and then conceal it by plastering or conceal it with skirting boards and decorative corners. To install the socket box, make a hole in the wall first. After the wire is inserted into the wire box, the wire box lies in the hole and fixed, fix the wire to the panel, and fix the panel on the wire box. The method of installing the power switch is the same as that of the socket box. 3. The wire should use copper wire and be configured according to the electricity capacity. Not too thin. It is recommended that the wire diameter of the air conditioner use 4 square millimeter wires; sockets use 2.5 square millimeter wires; general lighting fixtures use 1.5 square millimeter wires. In addition to passing through the hollow floor slab, wires must be routed through pipes; wires of different voltages, such as lighting wires, telephone and TV wires, cannot be worn in the same pipe; the power socket panel should be the left neutral wire, the right phase wire, and the upper ground wire. Wrong connection; the neutral, phase, and ground wires should be of different colors.

Electrician acceptance criteria: 1. When designing wiring, implement the principle of strong current going up, weak current going down, horizontal and vertical, avoiding cross, beautiful and practical. 2. The groove depth should be the same, generally the diameter of the PVC pipe +10MM. 3. When wiring the power cord, the cross-sectional area of the wire used should meet the maximum output power of the electrical equipment. In general, the lighting is 1.5 square meters, the air conditioner on-hook and sockets are 2.5 square meters, the cabinet machine is 4.0 square meters, and the household line is 10.0 square meters. 4. The laying of hidden wires must be equipped with flame-retardant PVC pipes. SG20 tube for socket and SG16 tube for lighting. When the length of the pipeline exceeds 15m or there are two right-angle bends, a cable box should be added. The lamp position on the ceiling is fixed with a cable box. 5. PVC pipe should be fixed by pipe clamp. All PVC pipe joints use matching joints, which are glued firmly with PVC glue, and all elbows are bent with springs. The cassette, the cable box and the PVC pipe are fixed with a gong.
