1, electrical installation works
(A) General provisions
1, power distribution box, after the table should be based on indoor household electrical equipment, wiring different power supply, respectively; high-power appliances should be independent of wiring installation socket.
2, wire divided into: light line, outlet line and air-conditioning lines.
3, weak, that is, telephone lines, network lines, cable television lines, audio cable, video cable, audio cable and so on.
4, wiring, when compared with the color line and zero line should be different; the same residential phase line (L) color should be uniform, zero-line (N) is appropriate to blue line of protection (PE) must be yellow-green color line. sun box,
5, completion of the project, shall provide the owners of Electrical Engineering-built drawings.
(B) selection
1, the metal wire to protect pipes and junction boxes should not be folded flat and the appearance of cracks in pipe should be no burr, pipe mouth should be flat.
2, communication system uses the terminal box, terminal box and distribution system, switches, sockets, should use the same products.
3, the installation and air leakage protection switch junction box of the project can not be provincial, but do not put outdoors to indoors, the original will want to save wages outside the Box with the old points, the electrician to put the proposal for indoor new, this proposal is now found him very valuable. Door on the interior is not bad, really easy to use them!
4 pairs of wires cassette shallot mm, the plan goes on to be a description, that satisfied the child, that is, to a fixed screw and buy cassette when the cassette should pay attention to buy the child can be satisfied that the activities of the kind. kxo DX made a mistake, accept that the child is a white plastic mount, I might not ring a good! However, kxo DX said that this screw is also very reasonable. Satisfied that the child on the one hand serve to connect the fixed cassette and line management role, the other is to protect the wires.
5, can afford to replace the phone line with the network cable, that is, telephone lines and network lines to row with the network cable. Because the network cable has 8 lines, telephone use one of the two, can effectively reduce the risk of accidental disconnection, while the telephone lines is indeed a high probability of failure.
6, the current PVC pipes are generally two kinds of 6 points and 4 points. If conditions permit, use the 6 points.
7, proposals are all using the brand name energy-saving light bulbs. To large supermarkets to buy.
8 require electricians must use shrink then. The new cassette must be connected to the electrical shrink Then, try to use shrink then the old cassette. Then shrink in order to prevent scratches wire, as well as the exposed wire.
9, you can use the embedded fluorescent Panasonic, I have living room, restaurant, bathroom, kitchen with all of this, turn on the lights, then it is natural light. My family's living room is useless chandelier, is fluorescent. In addition to other decorative chandeliers, no use, but also a waste of money and electricity.
10, at home, the vast majority of the family as a single-phase electricity into the households of each family into the line three: phase wire, neutral wire and grounding wire. Wire Color: phase line yellow (or red, green), neutral line is light blue, grounding wire for the green / yellow color line. This three-line into the household distribution box, its outlet installed in the family cross the color should be selected according to the standard. Arising from the household distribution box ground wire, you must use green / yellow color line. The color of individual lines must be light blue, phase lines and into the line of color could be more consistency, but also use several color lines, to distinguish between different output circuits. For example, the yellow line into the line, there are four qualifying circuit, can all use a yellow wire, can also be yellow, green and red colors of the wires in order to check the lines, it can expeditiously locate the fault line.
11, when the lightning hit to or sensitive to low-voltage overhead line, its high pulse voltage generated along the overhead lines into the room, will be damaged and power lines connected to electrical equipment, so that households installed lightning protection devices (also known as surge voltage protection device, known SPD) is necessary. Lightning protection device is a low-voltage power supply protection device, it can in the shortest time line for the release of a large number of pulses generated by lightning energy, transmitted through the ground wire to the earth. Lightning protection devices have caused modulus product. Household distribution box mounted on one end and phase line or N lines connected with the ground wire connected to the other end. Under normal circumstances, the SPD in a high-impedance state, when the household power supply into the line due to lightning or the switching operation occurs when the transient over-voltage pulse, lightning protection device immediately nanosecond time, the rapid short-circuit conduction, the pulse voltage leakage and going into the earth, thus protecting the household electrical equipment. When the pulse voltage flow through the SPD, the SPD has become a high-impedance state, therefore do not affect the family power. OBO foreign products in Germany is currently the company's V25-B enhanced power supply arrester, Merlin Gerin Company LTD / LTM surge inhibit the device, Haig's SP series surge protector devices. China has Zhejiang Cyclones, Shandong Longda and Beijing break the company's series of sockets. sun box,hd box,search box,packaging box,storage box,google box,multi box,photo box,dvr box,email box,network box,electrical box,jewelry boxes,watch box,orange box,test box,digital box,package box,gift box,plastic box,small box,boxes,display box ,home box,box store,service box,box truck,mega box,up box,box panel,jewelry box,case box,cable box,box size

u cable to save money Dafa: network cable is its most expensive star-shaped connection request. too much charge the line, saving money approach is that we can and phone lines to share, you can also share a two network interface cable, but the meaning Decoration reference not because it would not have so many joints. there is a way to save money, cloth bus, do not have to do a short connector route, provided that at the same time there is only one Ethernet port Internet access, and must find a cheaper cable interface module.
Another is the material had to save money. A lot of TX are flexing their use AMP, AVAYA, panda. In fact was an opportunity to fleece, and the indicators may also lower. Posted a home-made our company certified cable (on the right, and a one meter). Note that four kinds of white lines in the color, orange and white, blue, brown white, green, white, very clear and beautiful. electrical specifications, not to say. hard-won from the IT, where one can find comparable to the cable (on the left is a one meter), Germany MOLEX (Shanghai production). So, cable is not more expensive the better. it the value of a dollar. visual method can be used to identify, is the four kinds of white lines is not clear and beautiful.
I give myself drew an extremely complex network cable telephone lines to save money layout is very fearful of electricians do not know, he always said no problem. One day, suddenly told me that all the fabric better. Startled. A careful investigation, found that all is the most wasteful use of exclusive star join, he said, it is because you are buying are more lines. Of course, the most economical or by using a wireless AP.
u cable TV cheaper method: In fact, I have no home province, as, for six Mao's one-meter is also no need for the province. TV lines can be tree-routing, that is, to buy the distributor of many a sub-2, a section of a cloth. more appropriate to home, house, slender TX.
u sound line: the square of the power cord with 4 bar. Do not use special lines, boring. dedicated audio line like LV handbag, very good value for money but I will not buy. In the audio context, the basic transmission line model is not practical, copper loss should also be similar. The only possible difference is that the human ear on the audio signal-noise ratio requirement is relatively high, so the best use shielded cable. pipeline step as far as possible away from the row of strong electricity.
u Furthermore, all of the lines are present oxidation problem, the more expensive line of the more squeamish. often see such a high price and speaker on the audio line of a pick, a lot of lint exposed to the air. is like the Rolls-Royce on the open-air rain the same parking lot. leakage, trip, low-voltage electricity in Shanghai frequently encountered problems. These can all be by increasing the electric circuit to be resolved or eased. Therefore, in this regard is not to save money and the provincial workers. If it is three-phase access, attention must receive a different circuit to different phase lines. In use, plug appliances also may lead to short-circuit these incidents, so the sockets and lighting never share a circuit, or in a After the stupid mistakes you will face an endless darkness. The use of a few years later, poor contact socket is also very annoying, so carefully selected outlets. The design and location of the switches to be refined further scrutiny, the quality of life as reflected in this bit by bit. Wires carry a maximum current can generally be seen as a cross-sectional area multiplied by 10. Or 1.5 square line can carry 15A, 2.5 can carry 25A. But no need to use at home to challenge the limits, may be appropriately relaxed. In particular, long-term use of some large current loop, it is best to leave enough headroom. Otherwise, a long period of high current caused by heating will accelerate the aging of wire insulation. Several high-current electrical appliances are commonly used in electric home appliances category. For example, electric oven, electric heater, Yuba and so on. Air-conditioning is not present, air conditioners require a separate circuit reason for this is because it is the ripple current, long-term use and may have auxiliary heating. wire brand is not think many people would imagine that important . Shanghai people are very like the panda is not the first brand in the country. as long as the Great Wall and follow the ISO90002 certification of the company's products are in fact trustworthy. specific to the operation, in the B & Q you can compare a place like this, like the Starship , GP sort of line is good.
u Single-line skin is generally insulated from the role of flame-retardant wire and tube resistance from wave functions. Therefore, the connection wire and tube construction, must be close, especially with the associated cassette. should be confined, or moisture easily into. should be a good line and then wear a wire and tube construction. wire-line tubes not too much, the national standard is 40%. more would cause the accumulation of heat to accelerate the aging of insulating layer. good wire management should not be easily bent, 100KG weight of people stand up is all right; lighters to the point, it will only melt, there will be no open flame. pipes should be smooth vertical and horizontal, and left with a digital camera drawings. or in the future even if you want to play a hole in the wall, hanging a painting, are likely to cost a precious life. ceiling is also a wire inside the tube is to wear, because it is burning in order to solve the problem.

(C) the amount of
² strong electricity in several road
u can look at a general estimate. The following is the relationship between the amount per unit. 1mm square of diameter can withstand the current 6A, and every 1KW of electrical power needs of about 4A. This is the empirical formula, if accurate calculation of the words would be a little more than 4A. However, 1mm square of wire and can withstand the current 6A is a conservative algorithm. If the low pressure in accordance with regulations and textbooks in Shanghai's calculations, you'd had a little trouble. Need to consider is the inductive load or a resistive load, and then multiplied by different factors. I think that there is no need so much hassle home improvement, and empirical formula is sufficient.

4, power socket and a variety of junction box according to uniform standards for construction of high and low, to prohibit all kinds of wiring cassette gypsum powder with water-based fill inserted, we must use high-grade cement mortar fill inlay, all kinds of cassette slot four sides must be greater than 2cm above, to facilitate cement embedded into the mortar to see the award, is strictly prohibited, and a box size of the hole in the wall almost.
5, line pipe and cable boxes must use the lock interface.
6, wiring the middle as not to joints, otherwise a long time, easy access to undesirable.
7, dark line must be accompanied by the laying of pipes. Trench on the wall directly buried cables may cause leakage and thus cause a fire. When the pipe length exceeds 15m, or there are two right-angle bend, pull boxes should be introduced.
8, electrical wires must do jack 2.5m2 line, air-conditioning lines 2.5m2 line, closet air-conditioning 4 m2 lines, need to be a one-way alignment, lighting 1.5m2-line one-way alignment, into the family line above the 4 m2. Air-conditioning lines are rows of new houses are good. Therefore, under normal circumstances air lines need to be increased.
9, wire routing, pay attention to color separation, that is in accordance with international practice, the line in different colors. Yellow, and green line for grounding, the Blue line is the median line, red, yellow and green are the pick of three-phase line (FireWire) is. In a family should not be only a color phase lines, should be used to distinguish between different colors loop. in the light switch, especially double-switch, it is best to distinguish between the line of control. However, in this respect, the national standard does not dictate the . Separations wire construction is the most important point, because it provides for future troubleshooting a great convenience. This is a back door must remain good. in particular, and the middle ground, with other colors to be any death The.
2, electrical shunt must be in strict accordance with the requirements of owners and construction drawings and construction standards for construction, shall not be allowed to modify. Should be based on location of electrical equipment to determine the pipeline direction, elevation, and switches, sockets position.

10, electrical wires must be in excellent brand and quality of the string of pipe emissions from single-core line, line pipe to maximize the use PVC6 charge. The same circuit wires should be penetrated with a tube, but the number of total root tube should not be more than 8, the total wire cross-sectional area (including the insulation jacket) should not exceed the pipe cross-sectional area of 40%, and do Withdrawing freely.
11, 4 tubes of 1.5 can only wear light line, and a pipe can only wear up to three wires. 6 in charge of the child can wear a 2.5 cable, a tube is also a maximum of 2.5 can only be worn three wires.
12, construction end of a thread must be placed in electrical junction boxes, connectors must be used after the end of a thread screw cap tightened with the pressure line. Penetration piping wire connector should be located in terminal box, lap joints should be solid, insulating tape wrapping should be uniformly tight.
13 rooms and wire-to-ground wire between the resistor must be greater than 0.5MΩ.
14, PVC pipe elbows should be used the whole tube bending, only in compelling circumstances can only use 900 elbow.
15, PVC pipe should be used to dock connector, and then use the glue firmly. And the PVC pipe and wire connections between the boxes must use a dedicated cap to trap, do not directly use PVC pipe and wire boxes docking.
16, wire tube should be the first to use a good adhesive tape and then string wire inside.
17, line pipe, if cut, and and another put together the root of the site, use the tube. Connected to the Box go to use pressure foot cap.
18, cable docking handled? Often used in industry, without welding, using a dedicated compression terminals, voltage drop is very small, pull-out strength is greater than 200n (my test), domestic ks terminal, crimping tool 200 or so, terminal about 0.2 / a 1000 minimum packaging , imports more expensive. and my unit of electrical engineers and say, I prepared a professional terminal crimping.
19, each cassette where to stay a certain amount of lint (to prepare for future maintenance and replacement), metal exposed at the small to the extent possible. As necessary to get a clean dust. Connected to strong solid. GB where the connection request line must be Crimp cap, but do so in the home improvement market, less than 1%.
20, line box wires to extend 15 centimeters, and to ensure that you can pull, we can test it.
21, my nest is a small split-level, network lines, and line length is very long, the middle can not help but have some bend where the number of cable I have a moment, there are seven or eight bend, the line is certainly not twitch of the . The answer is affirmative: in two or three places where elbow set up a relay box, each section can be twitch on it.
