Acceptance by qualified customers and constructors is required to perform procedures such as ceiling cladding and wall closure. 12. After passing the electricity test, the customer will sign the approval, the electrician will draw the sketch, and the designer will send out the circuit fly chart to the customer. 13. The distribution box shall not be displaced without the permission of the power supply or property department. Leakage protectors should be provided in the distribution box of each household. Air-conditioning sockets, kitchen sockets, bathroom sockets, other power outlets, and lighting power supply should be separately shunted, and their circuits should ensure that the load is used normally. The load of the sub-routes must not exceed the load of the entrance line. 14. The process standards shall comply with the following requirements: a) The total cross section of the conductors in the pipe shall not exceed 40% of the cross-sectional area of ​​the pipe's inner diameter. The conductors in the pipe shall not have joints and kinks, and conductors of different voltages must not be mixed in one pipe. b) The grounding protection should be reliable, and the phase zero and phase resistance value should be greater than 0.5MΩ. The metal wire pipe, metal hose, distribution box metal bottom case should have ground protection; the kitchen and bathroom metal ceilings and lamps with height less than 2.4m should be The metal shell should have ground protection. c) It is strictly forbidden that the line pipe shall be laid directly under the floor under the compound floor, under the carpet, and in the kitchen and bathroom.

III. Equipotential equipment 1. Definition of equal potential: In order to ensure that the grounding resistance of the electrical equipment and metal conductor is the same, the ring grounding net is set 2. Equipotential bonding 3. Equipotential bonding is one of the main measures to prevent electric shock accidents in low-voltage AC power distribution systems. The main equipotential bonding is the use of metal components, central heating pipes and air-conditioning systems in buildings that will protect trunk lines, trunk lines or general ground terminals, utility pipes (such as water pipes) and similar metal parts in buildings, and available buildings. Connect each other and connect similar components and pipes into the building near the entrance in the building, to equalize potentials, reduce contact voltage, and eliminate dangerous voltages introduced into the building by power lines. The purpose is to make the electric potential between the exposed conductive part and the outer conductive part touched by people at the same time approximately equal, that is, to lower the contact voltage below the safe value, to prevent the lightning high voltage on these items or lightning on the grounding device. Ground potential transmission causes counter-attacks in the equipment insulation and cable cores. 4, the equipotential position Under normal circumstances, the equipotential installed in the bathroom, reasons: a. bathroom is generally installed with a bath, shower room, metal gussets, so the instantaneous voltage generated along the metal pipe into the bathroom can cause personal injury; b. Bathroom washing machine and other equipment shells are prone to leakage during transient high voltage. 5. Construction process requirements: The isoelectric potential must not be moved or damaged, and if necessary, a detection port must be reserved. Fourth, gas pipe production and installation: 1. According to the design requirements to determine the direction, calculate the length of the tube, stock preparation, cutting materials, on-site twisted teeth. 2. The use of galvanized pipes for gas pipelines should not be less than 6, and the use of threaded connections, twisted teeth need to be twisted into eight, leaving three to do maintenance, into the teeth after the fixed shall not be twisted. Artificial gas and natural gas joints use special raw material belts. 3. After the gas pipeline is installed, it is firmly fixed and arranged in neat rows with a horizontal distance of 500mm. The vertical distance of 1000mm is fixed by a pipe clamp, and the gas meter must also be firmly fixed. 4. The direction of the gas pipeline does not affect the safety of other pipelines, and the horizontal pipeline should have a gradient of 3-5 。. 5. After the gas pipeline is connected, it must be tested and accepted by the U-shaped table to prevent leaks. After acceptance, install the gas valve. 6. Note: The process standard should meet the following requirements: a. The gas pipe shall not be concealed and shall not pass through the bedroom. The gas pipe straight through the top of the ceiling shall not have a joint. The owner of the pipe larger than 3m in length shall be purchased and installed by the owner. The pipelines in front of the gas meter's clothing and watch must not be moved or replaced. The owner must obtain the consent of the relevant department if it needs to be moved. b. The distance between the gas pipeline and the wires in the same plane must be greater than 100mm, and the distance between the wires in different planes must be greater than 50mm, and the distance between the electrical switch and the socket must be greater than 150mm; gas water heaters must not be placed in a closed cabinet. (Acceptance of concealed project acceptance, customers, quality supervisors, and construction team leader may sign the approval of the concealed project acceptance to enter the next process.)
