How many square meters of household wires are there, and where are they used?

Lighting wires in your home.

Lighting wires are squared. Generally, the power of the home lighting load is not too large, and there are almost 6-8 lamps in the dining room, living room, main and secondary bedrooms, balconies, kitchens, and bathrooms, which are controlled within 1500 watts, and the square national standard copper wire is enough.

Wire for water heater socket.

The water heater is relatively large in household appliances, it is recommended to use 4 square wires, 4 square copper core wires can allow a maximum load of 7000-8000 watts, and the limit value is 8000 watts. Therefore, even if the water heater or bath bomb is turned on at the same time, there will be no major problems, and even if it is overloaded, it will only trip.

Wires for air conditioning outlets.

The air conditioner is also a high-power electrical appliance at home, so the socket is also a 4 square wire, of course, you can also use 6 square wires, but the construction difficulty of doing so will increase, and the area occupied by the socket bottom box will also become larger, and the wiring will become a very troublesome thing.

Wires for ordinary outlets.

The ordinary socket at home can use square wires, and the general load is controlled within 2500 watts. However, if you often use high-power electrical appliances, it is still recommended that you choose a 4 square wire.

Wires for kitchen outlets.

It is recommended to use 4 square wires for kitchen sockets, on the one hand, because there are many appliances in the kitchen, and on the other hand, because of the high frequency of use. Some kitchens are a square line to the top, and then arrange the socket below, with a square wire to connect the fire, all the sockets are connected from the square line separately, therefore, this practice is no problem.

Wire Specifications Square Millimeters.

Not commonly used are square millimeters, etc. Flat copper wire = 4 flat aluminum wire.

5 4=20a plus 20 electricity through the tube.

That is to say, choose a flat copper wire or 4 flat aluminum wire, and they can carry a current of 16A under the condition of passing through the pipe. With 5000w electrical appliances, a few square wires should be used, and the wire load current value (partial) specified in the national standard

Copper core wire: The cross-sectional area of copper core wire allows for long-term current.

Square millimeters (16a, 25a), 4 square millimeters, (25a, 32a), 6 square millimeters, (32a, 40a).

Aluminum core wire: The cross-sectional area of the aluminum core wire allows for long-term current.

square millimeters (13a, 20a), 4 square millimeters, (20a, 25a), 6 square millimeters, (25a, 32a).

For example: 1. The power consumption of each computer is about 200 300W (about 1, then 10 computers need a square millimeter copper core wire for power supply, otherwise a fire may occur.

2. The power consumption of the large 3 HP air conditioner is about 3000W (about 14A), so 1 air conditioner needs a separate square millimeter copper core wire for power supply.

3. The current housing incoming wire is generally 4 square millimeters of copper wire, therefore, the household appliances that are turned on at the same time shall not exceed 25A (that is, 5500 watts), and it is useless for someone to replace the wires in the house with 6 square millimeters of copper wire, because the wires entering the meter are 4 square millimeters.

4. In the early days of housing (15 years ago), the incoming line was generally a square millimeter of aluminum wire, therefore, the household appliances that were turned on at the same time should not exceed 13A (that is, 2800 watts).

5. The household appliances with relatively large power consumption are: air conditioner 5A (horse), electric water heater 10A, microwave oven 4A, rice cooker 4A, dishwasher 8A, washing machine with drying function 10A, electric water boiler 4A In the fire caused by the power supply, 90 are caused by the heating of the joints, so all the joints must be welded, and the contact devices that cannot be welded must be replaced in 5 10 years (such as sockets, air switches, etc.).

Household wires are mainly used in BV single-core copper wires, divided into square, square, 4 square and 6 square, square is mainly used for lighting wiring, square is used for ordinary household appliances socket wiring, 4 square is used for kitchen and bathroom and air conditioning, and 6 square is used for relatively high-power electrical appliances. A-line home is a building materials sale** You can check it out.

There are two main types of household wires: square and 4 square.

Square wires are mainly used for lighting wiring and socket wiring for ordinary home appliances.

The 4 square wire is mainly used for some high-power power-consuming electrical appliances such as kitchens, bathrooms, and air conditioners.

Household wires can be divided into 10 square, 6 square, 4 square, square, square. Ordinary switches and sockets can be squared. Air conditioning with 4 squares. If there are many electrical appliances in the kitchen and bathroom, you need to use 4 square meters.

It is better to use 10 square meters for household wires.

Household wires will be used in square, square, 4 square, 6 square and 10 square, different power connection positions have different requirements for the square of the wire, in order to adapt to various electricity situations, generally use 10 square.

5 square wires are used for single-way lighting fixtures, and their power is generally within 200W, which can meet the needs of use. The 5 square wire is used for switching lighting, ordinary sockets and other connections, it can carry a power of less than 4400W, and it can be used safely for electric fans, table lamps, and high-brightness lamps.

4 square wires are used for high-power electrical socket connection, including kitchen microwave ovens, ovens, rice cookers and other electrical appliances, bathroom water heaters, and living room, bedroom air conditioner within 2 horses, these electrical appliances are connected to the socket wire, all need 4 square to meet the requirements of safe electricity.

The 6 square wires are generally used for 3 or more air conditioners, as well as the sockets of ** air conditioners, and they should have a separate circuit to avoid sharing wires with other electrical appliances. 10 square wires are used in the home entrance bus to carry the power of all electrical appliances safely.

Precautions for the purchase of household wires

Look at the packaging

On the packaging plate of the wires in rolls, the "Great Wall Mark", "CCC" logo and production license number of the China Electrical Products Committee are displayed; The surface layer of high-quality wire insulation is bright in color and delicate in texture, and there should be no open flame when the surface of the wire is ignited with an open flame. The informal product uses recycled plastic, and the appearance of the color wine is dull, and the texture of the horn tentacles is loose and can be ignited by an open flame.

Look at the appearance

The insulation (sheath) layer of qualified wire products is soft, flexible and elastic, and the surface layer is tight, smooth, no roughness, and has pure gloss. The surface of the insulation (sheath) layer should have clear markings that cannot be easily erased. Products produced by informal insulating materials have poor insulation texture, unsaturated color, transparency, and no toughness.

Household wires should be squared.

The wires used in home decoration are generally divided into two types: sheathed wire and single-strand wire. The sheath wire is a separate loop, which is protected by a PVC insulating sleeve outside, while the single-strand wire requires a constructor to form a loop and connect a special PVC conduit before it can be buried in a wall.

Wires can generally be divided into the following types: plastic copper wires, which are generally used together with threading pipes, and are mostly used in concealed projects in building decoration construction. In order to distinguish the zero, fire and ground wires of different lines, different surface colors are designed, generally the red line represents the "fire line, the two-color line represents the "ground wire", and the blue line represents the "zero line", but due to the construction of different occasions and different conditions, the color distinction is not the same.

Household wires are usually better in square, squared, and 4 square.

A wire is made up of one or several soft wires with a soft sheath on the outside. A cable consists of one or several insulated wires wrapped around a tough outer layer made of metal or rubber. Cables and wires are generally composed of three components: core, insulating cover and protective sheath.

The characteristics of commonly used cables are ethylene propylene rubber insulated neoprene sheath, marine flame retardant power cables. PVC insulated, PVC sheathed marine flame retardant power cable.

The oxygen chamber wires are often made of BV, BX, RV, RVV series wires, including copper core PVC insulated wires, with a long-term allowable temperature of 65, a minimum temperature of -15, a working voltage of AC 500V, DC 1000V, fixed laying indoors and outdoors, and can be applied openly or darkly. Copper core rubber insulated wire, the maximum operating temperature is 65, and it is applied indoors.

Directions for use:

Lighting socket: It is best to use flat eyes for lighting wires, because the lamps and lanterns connected in series such as downlights and spotlights at home will generally not exceed 500w, and the wattage of large crystal chandeliers will not exceed 1000w, and the square national standard copper wire is sufficient.

Special socket for high-power electrical appliances: air conditioner and water heater socket use 4 square wires, but many friends will use 6 square wires for the sake of safety. Although it is indeed safe to do this, the difficulty of manual construction has become greater, the area occupied by the socket bottom box will also become larger, and the air conditioner still uses 4 square wires.

Kitchen socket: Use 4 square wires because there are many electrical appliances in the kitchen, such as range hoods, rice cookers, microwave ovens, soy milk makers, boiling kettles, etc. Some owners have a 4-squared line to the top of the kitchen, and then arrange the socket underneath and use the square wire to connect the fire.

It is also advisable for all sockets to be connected separately from 4 square wires.

Hello, I will answer for you about how many square meters of general household wires, how many square meters of general household wires to use, I believe that many friends do not know, now let's take a look! 1. In me. <>

Hello, I will answer for you about how many square meters of general household wires, how many square meters of general household wires to use, I believe that many friends do not know, now let's take a look!

1. In my opinion, it is enough to have it, and if you are four squares, you can connect the air conditioner, of course, the amount of wire material must be real material.

2. If there is a surplus of funds, it is another matter.

3. The aluminum wire is not completely unusable, the resistance is a little larger, and it is estimated that the requirements will be thicker.

4. If you consider adding air conditioning in the future! It's best to get 4 square meters in advance! Save the trouble in the future!
