1. Temporary power supply security Temporary power supply on the construction site shall have complete plugs, switches, sockets, and leakage protection devices, and cables shall be used for temporary power supply. Power cord is divided into three colors: FireWire red. Zero line blue. Ground line yellow. All one-way outlets should be "left-zero-right-fire-middle" or "lit-down-zero" connections. 2. Independent use of leakage protector The power supply circuit of each room outlet, and the power supply circuits of the kitchen, bathroom, and bathroom should each independently use the leakage protection device, and must be connected to other power supply circuits, and must not overlap its zero line with other circuits. 3, high-power electrical circuit Air-conditioning and other high-power appliances, must set a dedicated power supply circuit, air conditioning using 4M2 power cord, lighting line 1.5 ~ 2.5M2 power cord, all power outlet power supply circuit should use 2.5M2 power cord. Other power supply loads refer to this standard. 4, into the wall wiring matters All PVC-incorporated wires in the wall are buried in 20 PVC smoldering pipes, and connected with elbows, straight sections, junction boxes, etc. There must be no joints in the bottom of the cup and comb pipes. Do not expose the power cord to the ceiling or use it directly. Cement is applied to the wall to ensure that the power cord can be pulled or replaced. 5, power line tube through the ground under the matters Under special conditions, when the power line pipe is passed under the ground, special attention should be paid to the use of a tight connection under the ground. Under the ground, the connection of the source line to the ground must not be used. Before the floor is not closed, PVC casing must be well protected and no breakage damage is allowed. When laying floor tiles, PVC casing should be completely covered by sand financing. When nailing wooden floors, power lines should be laid along corners to prevent power cables from being nailed. damage. 6, horizontal and vertical alignment The power cord goes horizontally and vertically, and cannot be pulled diagonally, and avoids wall mirrors and objects. The installation position of furniture, etc., to prevent being hammered. Nail damage. When the power cord is buried, it should not be considered with electric heating. Guangzhou interior decoration, Guangzhou cleaning company Shui Ting. Water pipes and weak current lines are maintained at a distance of 500 MM or more. 7, the power line tube fixed in advance The power line tube should be fixed in the wall groove in advance, to ensure that the surface of the sleeve recessed above 13MM, (groove depth of the wall 33MM) 8, after connecting qualified wet wall After inspection and approval, after the power line is connected, it shall be wetted and wetted with 1:2.5 cement mortar. The surface of the seal shall be leveled and shall be 2 mm below the wall surface. The power supply box should be firmly installed, and the bottom of the panel should be flat and fits the wall surface. 9, switch setting considerations The air-conditioning power supply adopts 16A = hole socket, in the children can touch the height (1.5M below) should use the outlet with a protective door, bathroom. wash room. The bathroom shall be equipped with a splash-proof socket, with an installation height of not less than 1.3M, and away from sources of water. For comfort and convenience of living, the bedroom shall be equipped with dual-control switches. The kitchen power outlet shall be provided with switches in parallel to control the power supply and disconnection into the cabinet. The power of the microwave oven should be set on the wall to control the switch. 10, socket interface rather more lack of lack A variety of strong and weak electrical socket interface rather than lacking, the two sides of the bed should be set with a power outlet and a telephone socket near the computer desk, the living room TV cabinet wall should be set to 3 power outlets, and set the appropriate TV. phone. multimedia. Broadband network and other outlets. Switch box is generally 1.2 meters from the ground, a room with a multi-use socket. 11, outlet switch height consistent All plugs. The switch should be higher than 300MM above the ground. The socket and switch height in the same room should be the same (height difference<5MM is a height difference<1MM and will not be blocked by sliding door furniture and other objects. 12, rocker switch installation The rocker switch shall be installed in the same direction with the lower end pressed in as the top end and pressed into the wall. When the panel is tightened, the screws used for supporting shall not be replaced with wooden dowels or plasterboard screws to avoid damaging the bottom box. 13, reliable lighting of metal lamps The metal shell of the metal shell is reliably grounded. The live wire should be connected to the center contact of the screw base. The lamp should have a large number of lamp holders with a yellow wax tube on the wire. After the wire is connected, the lamp wire should be scattered. 14, weak electricity laying method The laying methods and requirements for weak lines such as audio, television, telephone, multimedia, and broadband networks are the same as those for laying the source lines. They are installed off-site from the outlets or boxes and outlets, but the weak and weak lines are not Allow a total of one set of tubes, the separation distance of 500MM or more. The audio cable should be used as a bottom box on the wall, behind the speaker, and no open line is allowed on the wall. When not in use, the speaker can be placed in the bottom case and covered with a panel. If there is no special request from the customer, the telephone lines in all rooms should be combined into a single number. If there is a distribution box on the floor, the telephone line should be connected to the distribution box. At the joints of the multi-core telephone lines, the casing openings should be tightly packed with tapes to prevent the phone lines from getting wet and crosstalk from occurring. 15, strong and weak electricity installation detection method Weak and weak electrical installation quality inspection method: Weak electric wires must be short-circuited and measured at the other end. The power socket shall be tested with 220V light, and the insulation strength shall be measured with a megohmmeter. The insulation strength between the wires shall be 0.5MQ. . The telephone line connector must have a dedicated connector. The above is the relevant content of the circuit installation construction specification. In addition, we must remind that all main and auxiliary materials in the circuit and waterway reformation adopt national certified products. Strength and weakness circuits and waterways shall be maintained at a distance of more than 500mm between each other when they are laid into the wall. The construction shall be covered with bare ends. After completion of the renovation of water and electricity, construction workers shall draw the hydropower reform as-built drawings according to their actual locations and submit them to the company for archiving.

How to arrange water and electricity installation and construction specification in home improvement is very important
The construction party should actively solicit the views of the owners, carefully listen to the requirements of the owners, determine the location of each power switch, water level appliance and hot and cold water faucets, etc. Only after confirming these details can the construction be started, which can effectively avoid Rework due to lack of communication.
