The ninth story of fence home decoration-electrical and electrical materials
It is not easy for programmers xdjm to buy a house. It has been laid by a developer or a second-hand house, and cannot be swallowed up by an installer, a building material dealer, a furniture dealer, or a soft contractor. We need to arm ourselves with knowledge and fight together with js to the end. Let's take a look at the fence home decoration series compiled by Leng Shan.

9.1. Wire of auxiliary materials
Http://video.liba.com/detail.php? Id = 77 & Aid = 1 precautions for wire Purchase: 1. the logo should be clearly printed, and there is no greasy feeling in the hand touch. There is no eccentric core in the cross section. Take a wire head bending repeatedly, should feel soft, strong fatigue strength, elasticity and no cracks on the insulator. Then peel off a piece of plastic jacket, high-quality copper color bright and soft, yellow in red. The color is dark and hard, and the product is poor. 2. standard length. The required length is 100 +-0.5 m. insulation Layer, made of polyvinyl chloride plastic special for wire and cable, pure bright color, fine texture, thickness 0.7 ~ 0.8mm, can not be torn by hand, with a lighter ignient fire. 4. When purchasing an electrical appliance, You must select the appropriate specification based on the electric appliance situation and leave a certain margin, generally 4 ~ 6 mm², air conditioning, microwave oven and other high-power electrical appliances applications 2.5 mm². Precautions for wire installation: 1. Ensure standard cabling, and ensure protection of cables. For fixed lines, pipe threading is required. A maximum of three wires can be used for 16mm pipe cabling. 2. Try not to have a joint in a route, and brush tin at the joint. 3. avoid hitting the wire when the wire is connected to the electrical box; otherwise, it may be dangerous. 4. Separate lines are used for electrical appliances with high power consumption. 5. The distance between strong and weak wires should be above 50CM to avoid interference.

9.2. "purchase of switch and outlet"Http://video.liba.com/detail.php? Id = 45 & Aid = 1 switch socket to watch six aspects: 1. Appearance, good switch socket surface smooth and smooth, no Burr, Phi peak, made of imported pc. Poor color, coarse texture, poor fire resistance, fire hazards. 2. Feel, the switch is light and not tight, the spring is hard, and the switch is powerful. Poor Switch Spring soft, easy in the middle, the Panel feels thin and brittle. A good socket Jack has a protective door, which cannot be inserted with a single foot. Pay attention to the same level during insertion, And the plug-in must be strong. 3. Weight. A good switch socket uses copper. The thicker the plug-in, the better the weight. Poor use of alloy or thin copper; 4. material selection, good switch socket panel is insulating material, can do the combustion experiment for identification, good panel off the flame of the fire when there is no flame. If the difference is, continue to burn; 5. Panel, a good switch socket must use a dedicated tool to remove the panel. Easy to remove. Identification Method: Use the index finger and thumb to hold down the diagonal corner of the panel, hold the opposite end, and press the other end. If the face cover is loose, it is poor. If there is no loose, it is good. 6. listen to the sound, switch button sound light, smooth feel, strong rhythm. Poor sound is not pure, dynamic stagnation has midway intermittent state; quiet Decoration: http://blog.csdn.net/magus_yang/category/826768.aspx
9.3. Installation of switch and SocketHttp://video.liba.com/detail.php? Id = 40 & Aid = 1 note! Improper installation of the switch and outlet may cause electric shock or fire. Improper installation involves four situations: 1. concatenate two wires on a pile head. 2. zero, the phase line is connected incorrectly; 3. the switch is installed on the combustible body, and the wire core is exposed or water vapor infiltrated, resulting in short circuit; 4. the working voltage and current do not match the power of the socket and are overloaded for a long time. Precautions for installing the switch socket: 1. switch should be 130 ~ 150, 15-from the door frame side ~ 20 cm, not suitable for installation after the door. Wall switches with wall panels should be at least 1.3 m above the top of the Board. The height of the open socket should not be less than 0.3 m from the ground, and the dark seat should not be less than m. The kitchen and bathroom should be set separately. Do not install on a bedside or desktop. The open and closed directions of all switches are the same; 2. the bathroom and balcony should be equipped with splash-proof sockets. The upper part of the bathtub, faucet, and stove should not be installed, and 15cm of the gas table should not be installed; 3. household Appliances do not use two-eye sockets. The Yuba switch is large and requires multiple locations. Electrical appliances that often need to be plugged in can be used with a switch socket; 4. computing load. The socket without fixed load is calculated by 1000 watts, and the common socket uses the 2.5 mm² copper core line; 5. the grounding line is connected to the Third-eye socket, and the left side is connected to the zero line and the right side is connected to the phase line. The two-eye socket is connected to the zero line on the left and the phase line on the right; 6. to be firmly installed, tighten the connector; 7. make sure that all wires are fully in contact with the head of the switch and socket head. the switch uses the opposite hand to open and close, and the right hand is more than the left hand. Generally. Door switch easy to use fluorescent type; 9. Pay attention to the protection of the switch or socket panel when the decoration, to prevent fouling; quiet Decoration: http://blog.csdn.net/magus_yang/category/826768.aspx
9.4. Common sense of switch and OutletHttp://video.liba.com/detail.php? Id = 39 & Aid = 1 There are six commonly used switches: 1. Single-link single control controls a single lamp or electric appliance. 2. Single-link dual-control means that two switches can control one lamp or electric appliance. 3. Each of the dual and triple single control functions is the same as that of single control. 4. The dual-connection and triple-control functions are equivalent to the single-connection dual-control switch. Types of sockets: 1. Broadband cable TV sockets can be connected to satellite TVs and wired communication signals at the same time. 2. The telephone outlet is used to connect the telephone signal. 3. The information outlet connects to the broadband signal line. 4. The telephone/information outlet can connect both the telephone and broadband signal lines. 5. 16A single-phase three-pole socket is used for high-power electrical appliances such as air conditioners, and has a switch socket. 6. 10a single-phase socket is used for general electrical appliances. 7. 20a single-phase three-pole socket is used for air conditioners with 3 P or above or electric appliances with a power of W or above. 8. 10a Single-Phase Two and Three-pole Sockets (with protective door), can be connected to two and three-pole plugs at the same time. 9. The blank panel is used for the reserved junction box. 10. The splash-proof surface cover is used to protect the switch socket where water is easily splashed. The basic requirement is one panel per two square meters. For example, 50 panels are required for a 100-square-meter apartment. It is best to reserve a panel for future use, one for every 1.5 square meters. For example, 100 square meters of residential buildings require 66 panels.
