When is the best time to install the switch socket for decoration
When the circuit wires are laid, the socket pre embedded box is reserved, and the switch socket can be installed after the modeling is completed after the woodworking is completed. But pay attention to the paint must be protected, to protect the socket switch clean and safe.
The installation method and procedure are as follows:
Height:
The power switch is generally between 120 cm and 135 cm from the ground (the height of the switch is as high as the shoulder of the adult)
The wall sockets of audio-visual equipment, table lamps, terminal blocks and so on are generally 30 cm from the ground (the living room socket is determined by the TV cabinet and sofa), the socket of washing machine is 120 cm to 150 cm from the ground, the socket of refrigerator is 150 cm to 180 cm, the socket of air conditioning and exhaust fan is 190 cm to 200 cm from the ground.
Generally, it is recommended to use the door switch with prompt light, which is convenient for night use. Otherwise, the wall on the side of the switch will be dirty for a long time. And grope to turn on the light, always give timid mm with a great psychological pressure.
Connection of multi switch:
Multi switch is a switch with several buttons, which can control multiple lights.
1) When the electrician is required to connect the multi switch, it is necessary to have logical standards, or according to the front and rear order of the lamp orientation, one by one, one step further.
2) If the kitchen exhaust switch is also connected to the multi switch, it will be placed on the last one. The switch of the middle control lamp shall not jump on, so that the function is separated, and it is easy to remember when it is opened later. Otherwise, it is often to find the light you want to turn on, and turn on all the switches.
3) Some sockets with switches can be set, so that plug can be disconnected and power can be cut off, and the wire pulled off will not affect the beauty, such as off-season closing of air conditioning socket without pulling off;
4) Kitchen socket should not be installed above the kitchen table to prevent overheating
5) Install bathroom bath bar switch, remember to leave a few centimetres more position, because this switch is generally a turn larger than the light switch, if it is less than a little bit of can not be installed in trouble;
6) One and one.5 air conditioning 16A socket in the home!
7) Normally, a general ground wire will be made, and the grounding of each socket shall be connected to the general ground wire separately.
The difference between the two lines is that the total ground wire is a complete, thick line. Mouse line is divided in several sections, with each socket grounding port as the node.
8) The simple calculation method is 0.75 switch sockets with a square meter, of which 70% are sockets.
However, it is recommended to leave a potential according to 1 square meter. If you don't need it for a while, install blank panel first (the line should be arranged and available at any time)
9) The switch of the bath bar is special, and cannot be used with the common switch.
10) The general small circuit breaker in the family is equipped with leakage protection circuit breaker. The circuit division is lighting line, Socket line, air conditioning circuit, etc.; and lighting line, Socket line and air conditioning line can be subdivided, such as kitchen, toilet, bedroom, hall, etc. after subdivision, the number of "a" power is configured according to the designed power consumption power under each line (a certain margin is reserved ）, leakage protection circuit breaker is used for socket line; the main switch can be configured according to the total power. The common control fire wire for household use 1p, control fire line and zero line 2p.
11) It is suggested that a part of the two three plug (five holes) be replaced by two two holes (four holes), especially in the back of the TV cabinet and the bedside counter. Because the TV, DVD, electric blanket, lamp, charger and so on used in these places are all plug with two holes, and five holes are not as practical as four holes.
It is suggested that some two or three plug (five holes) be replaced by three hole belt switch, such as washing machine (generally press on the wall on the washing machine), rice cooker and other kitchen electrical appliances.
It is recommended that the air conditioner be plugged in with switch. So when changing season, you don't need to pull plug, turn off the switch.
12) Air conditioning socket must buy 16A. Theoretically, 16a socket and plug are required for air conditioning above 1.5p.
13) TV is in standby mode, and the meter will go at very slow speed, which can be ignored.
14) There are several sockets in my house with switches, but TV doesn't work.
The main uses are: washing machine, rice cooker, air conditioning. When it is not used, the power supply is plugged in, which may cause misoperation.
15) When used, it will be found that two holes are required in many places. Especially in the bedroom bed and behind the television.
The bed has lamp, cordless telephone, electric blanket, and occasionally the cell phone is charged. So my bed is both sides of the five holes + two two holes.
There are two two two holes + one five holes in the back of TV, because TV and DVD are all plug connections.
16) Kitchen multi use three hole with switch (cooker, electric water heater, washing machine, exhaust fan and other cabinet appliances)
Two two holes are used in the room (one five hole and one two holes on both sides of the bed, two two holes in the back of the TV and 1-2 five holes)
The air conditioner socket is made of 16a3 hole with switch, so it is easy to pull the wire when it is not used
17) The water heater is installed on the top of the room. It is suggested to install a switch at a place of 1.5m. It is recommended to use 16A switch. Many brands have 16A specifications or all the switches are 16A. Connect the 16A switch to the front of the 16A socket. The switch is in the room, and the socket is pressed on the top.
18) Hang up air conditioning (main bedroom, guest bedroom, study each) individual likes to do a separate circuit. The rule is, however, that there are no more than two air conditioning in one loop.
19) Left zero right fire. The right and left are standard with the installed front, not from the back.
The fire line is l, n is the zero line, PE is the ground wire
20) The ground wire is 1.5 enough.
21) the fire line and zero line are specified as monochromatic lines, especially the zero lines, which must be blue. The fire line is generally red, but the operation of high-grade points can distinguish the corresponding circuit according to the color of the fire line. The fire line may also have yellow, green and so on.
The color of the ground wire must be yellow and green.
22) personal strong current layout plan:
(1) One way kitchen socket; (including: lampblack machine, xiaocookbao, electromagnetic furnace, bean milk machine, hot kettle, electric rice cooker, etc.) 20A 1p + n with leakage; 2.5mm2 line
(2) One way of toilet socket; (including: three in one bath bar, heater, small kitchen treasure of platform basin) 20A 1p + n with leakage; 2.5mm2 line
(3) Electric water heater is one way separately; 20A 1p + n is leakage; 4mm2 line
(4) Living room + bedroom socket one way; 20A 1p + n with leakage; 2.5mm2 line
(5) Kitchen + toilet lighting one way; 16A 1p + n; 1.5mm2 line
(6) Living room + bedroom lighting road 1; 16A 1p + n; 1.5mm2 line
(7) Living room air conditioning Road 1; 20A 1p + n; 4mm2 line (I install wall mounted, save space, so I don't need to take leakage protection)
(8) Air conditioning Road 1 in main bedroom; 20A 1p + n; 4mm2 line
(9) Air conditioning Road 1 in secondary bedroom; 20A 1p + n; 4mm2 line
63A main switch, 1.5mm2 wire for ground wire
A total of 9 + 4 + 2 = 15 bits, 16 bit strong power box is enough, and the other one is used as standby.
23) only 10a and 16A specifications are used for switches and sockets, and only air conditioning is equipped with 16A.
24) the microwave oven does not use 16A three holes, and it is better to use a 10A five hole, and it can also be used in case of two holes of electrical appliances.
25) use 10A five holes under the table. After all, most hot pot uses 10A plug, sometimes this socket can also be plugged into rice cooker.
26) the drinking water machine is plugged in with five holes. Sometimes a mobile charger will be inserted here.
10A five holes for electric kettle
The bath bar doesn't need a socket. This three pole one doesn't have to be installed
In addition to one five hole socket on both sides of the bed, a four hole socket is added to each side. There are many electricity equipment on the bed. It is more correct.
27）
1.5 lines can only be used for lighting lines
2.5 wire for socket
In theory, there should be 4 flat wires for air conditioning and electric water heaters.
28) the trend is to install the socket open, which is to install it on the top of the bedside cabinet, and do not be blocked, so that it is convenient to power. Look at the foreign interior design, many modern simple style are so installed. Put it behind the bedside counter, the bedside counter is to be moved forward, but it is not good.
29) socket circuit and cabinet air conditioning circuit must have leakage protection. If there is no shunt, only the general circuit has, it can also be. The advantages are cheap, the disadvantage is if leakage, jump the main gate, maintenance and determine the problem is more difficult. If there is no leakage protection in the branch circuit, it is a better design. If all, of course, there is no problem in safety, but it costs a little more, but maybe you can protect the leakage of lighting lamps.
30) DPN is a general term, including 1p + N, 2p + N, 3P + N, etc. *P is a few phase lines, n is zero line (this is not absolute, but it can be understood by zero line). DPN can realize the simultaneous closing of phase line and zero line.
1p + n is one of DPN, that is, one phase line and one zero line. In general, 1p + n is used in the home.
31) I suggest that the bedroom main lamp be turned off by double control switch so that both husband and wife can turn off conveniently.
32) 3-bit double control switch, if only one way to double control, it is recommended to use one one two control and one two bit single control, which should be cheaper than using a three-bit double control, and it is good-looking (generally, the three-position switch is ugly, the key is relatively small, and it is not easy to press)
33) the bath bar in the bathroom generally has exhaust fan and special switch, so it is not suitable. Only the dome and mirror headlights need to be equipped with switches. Of course, a dark box mouth is required next to the switch and a bath bar switch is placed.
34) socket principle:
(1) One two and three sockets shall be installed every 2.5m for standby. One two or three sockets shall be reserved for the interior affairs 1.5m away from the corner of the wall
(2) Anticipate all electrical locations and avoid long-term use of the towline board as possible (such as bed, TV cabinet, computer table)
(3) Proper reserve of weak current socket (such as TV plug-in in restaurant)
