At present, the installation of hydropower in the home is the most concerned issue for every owner. Each owner should not be bothered with the decoration and communicate with the construction party to ensure that he can use the hydropower function in his life in the future. Next Xiaobian introduced the installation of water and electricity precautions and installation of hydropower construction specifications. Next Xiaobian introduced the installation of water and electricity precautions and installation of hydropower construction specifications.
Installation of water and electricity precautions
1. The installation position and quantity of switches and sockets should be carefully considered when wiring. The principle is that it should not be less.
2. Under normal circumstances, the zero line is blue, the fire line is red, and the ground line is a yellow-green two-color line.
3. The cross section of each residential house entrance line should not be less than 10 square millimeters. This way, for ordinary families, the lamps and lanterns use 1.5 square millimeter lines, and the switches, sockets, and grounding lines can be used for 2.5 square millimeters, and for installing air conditioners, etc. Lines of high-power electrical appliances should go on a single 4-square-mm line. For the entire line, the number of branch circuits should not be too small, generally should be all the way to go lights, air-conditioning go two-way, sockets go three to four. The advantage of this is that once a circuit has a short circuit or other problem, the scope of power outage is small and it will not affect the normal operation of other circuits.
4. The height of switches or sockets in the same room must be the same. Generally, the switch is 1.4 meters away from the floor and 15 to 20 cm away from the door frame. 30cm from the socket is appropriate. The air conditioning hook socket is more than 2 meters above the ground, and the cabinet socket is 30cm above the ground. The kitchen socket is 1 meter off the floor (the height of the kitchen cabinet is about 80cm). Sockets on the countertop: such as bedside cabinets, vanity units, kitchens, etc., the bottom of the outlet should be 10cm from the countertop. Bedside double control switch height is about 85cm; Wall TV power supply height is determined according to the space size and TV size, the general height is 1000-1200MM.
5, in the wiring process, to follow the "fire line into the switch, the zero line into the lamp" principle; socket wiring to do "left zero N right fire L, ground PE on the" or "flame under zero." To prevent children from getting an electric shock, touching with a finger, or inserting a metal object into the power hole, be sure to use a safety socket with a safety cover. In addition, electrical appliances that need to be switched on and off frequently should be considered as outlets with switches.
6, the living room lighting should be installed in front of the entrance door and the bedroom door double control switch (so that at night to go to bed, go directly to the bedroom off the lights and then go to bed, do not touch the black door to find the bedroom). Similarly, bedroom lights should be installed in the bedroom door and bedside dual control switch. In addition, bedside lamps are recommended to install wall lamps instead of table lamps (space-saving).
7, into the account or bathroom mouth, you can consider installing infrared sensor lights (go home at night or get up, do not touch the black switch).
8, strong and weak electricity need to be slotted, separate laying (the spacing of strong and weak electricity should be 30-50 cm), and use cold pipe to thread (cold elbow pipe tool to use, arc should be the diameter of the line pipe 10 Times, so that threading or stitches can be smooth.
9. The principle of hydropower construction is that if you go to the top and you don’t go to the top, you can’t walk. Consider taking the wall and the wall can’t go before you consider taking the ground. The top line is inside the ceiling or plaster line, which is easy to overhaul. Walking away from the wall is afraid of damaging the concrete layer and even reinforcing steel bars, and avoids large-area lateral grooving, fearing that the bearing capacity of the wall will be affected. On the ground, the floor will be lifted during maintenance. Therefore, a large area of ​​electricity should be considered to go to the top or take the floor, if the ceiling has a ceiling, can be given priority, or consider walking the ground (bathroom, kitchen and other considerations to take the top).
10. Household units should be provided with their respective power boxes, and a leakage protection device with an operating current of 30A should be provided in the distribution box. After the splitter passes through the air, it controls the lighting, air conditioning, and sockets.
Installation of hydropower construction specifications
1, the principle of wiring: horizontal and vertical. Use a special PVC flame-retardant wire tube, the wire tube must be fixed in the wire trough, the lock box should be used when the wire box and the wire tube are connected, the straight tube uses a tube card every 80 centimeters, and a tube is used every 20 centimeters around the corner. card.
2. In the upper part of the wall, the socket shall be vertically slotted upwards until the top of the wall is installed in the installation line of the decorative corner line. If it is in the lower part of the wall, it shall be vertically slotted downwards to the bottom of the installation skirting board. The depth of the slot shall be Consistently, the slot line and the top line should be ejected after the control line on the wall, and then use a cutting machine to cut the wall surface and slot the machine.
3, the use of financial PVC pipe, in the elbow when the spring is bent, not to use 90-degree elbow and three links (at this point we basically did not appear this type of situation), line installation must be sheathed Glue is used for connection. The edge of the casing shall be tightly closed. Flat and smooth. The right angle shall be cut at the inside of the corner. After the arc-shaped interface is cut at one side of the incision, it shall be bent and installed.
4, moderate depth of pipe teeth, no burr. The pipe joints are wrapped with raw material and wrapped 5-6 turns. The number of pipe twisted teeth is 5 teeth-6 teeth until the joint is tightened, and rotten teeth are not allowed to enter the pipe.
5, after the wire is installed into the casing, the wire fixing tool should be used. After fixing the wire inside the wall and the wall, the plaster is concealed.
6. It is strictly forbidden to lay the line pipe directly under the composite plate. (At this point, we have not done very well at present. We will communicate with the customer well later, and the composite floor must be grooved.) The line pipe under the solid wood floor There must be reinforcement measures.
7. It is forbidden to lay the line pipe on the kitchen or bathroom floor to prevent water from penetrating into the line pipe.
8. The wire that passes into the line pipe should not be more than 40% of the hole area of ​​the line pipe. There must be no joints in the pipe wires, and the wires of different purposes must not be mixed in one wire pipe.
9, the wire into the box must be guaranteed to leave a certain length, leaving 10 to 15 centimeters, audio left 100 centimeters, wearing a hose to switch. Socket installation and maintenance.
10. The distance from the wall to the water pipe should be 1.5cm, left and right cold, and 15cm apart.
11. The parallel distance between the wire and the water pipe should not be less than 30 centimeters, and the crossover distance should not be less than 10 centimeters.
12. Wire points and points must not have joints, and the dark lines in the ceiling must have flame-retardant tube protection.
13. After the acceptance of water and electricity is passed, powder lined trough and wall trough can be filled and compacted with 1:3 cement mortar.
Editor's summary: The installation of water and electricity precautions and the installation of hydropower construction specifications are introduced here, and I hope to be helpful to everyone. If you want to know more about yourself, you can follow the information on this site.
