Why is it said that the thicker the wires used in home decoration, the better?

If you only talk about wires, the thicker the wire, the better - the thicker the wire, the greater the current carrying capacity, and the better the insulation. It is not prone to heat and leakage, so it is safer to use, but when it comes to the place of use, we can't just consider the performance of the wire. For example, the "decorative silk" we want to talk about here, in addition to silk, we also need to consider objective factors.

In the decoration environment (home), the increase in the thickness of the wires causes two disadvantages:

Associated costs increase.

It seems that 6 square copper wires are not much more expensive than 4 square copper wires. However, the increase in the filament side leads to a series of cost increases.

If the wire is thicker, the corresponding threading pipe should be thicker; The slotting depth should be increased; The backfill depth should be increased; Increase the size of the pipe clamp; Construction time should be extended – these are not only the cost, but also the floor height and time lost.

Less operable.

The thicker the wire, the more difficult it is to apply – in addition to the difficulty of slotting and burying pipes, there are also difficulties in wiring and maintenance. When the wire becomes thicker, it will become more and more difficult to pull, and it is easy to cause dead wires.

How to decorate with thick wires.

Choosing wires for decoration is more like choosing a pair of shoes for yourself - too big or too small is not good, the "Electrical Design Code for Residential Buildings" clearly stipulates: an area of 60 square meters below a bedroom, the main circuit uses 6 square copper wires; The lighting circuit adopts square copper wire; The ordinary socket circuit adopts square copper wire; The high-power socket circuit adopts 4 square copper wires.

Wires are the key to home décor. The quality of the wires is directly related to the safety of the whole family and is closely related to our family life. Therefore, we should pay enough attention to it, and when purchasing, we should understand more and compare more before buying.

In addition, the main circuit of the residential building adopts 10 square copper wires; The lighting circuit and the ordinary socket circuit use square copper wire; The high-power socket uses 4 square copper wires, which was implemented in April 2012 and is relatively in line with the electricity needs of today's families, and most home decoration is also doing so.

No, because coarse does not mean that the material is of good quality, so we should look for those wires with good materials and quality.

Because when decorating the family, the increase in the thickness of the line will cause two drawbacks, one is the increase in related costs, the wire becomes thicker, the corresponding threading pipe should also be thickened, the slotting depth should be increased, the backfill depth should be increased, the size of the pipe clamp should be increased, and the construction time should be extended, which is not only a cost problem, but also the loss of floor height and time. Second, the operability is reduced, and the thicker the wire, the more difficult the construction is. As the wire becomes thicker, it will also become stiffer, and it is laborious to pull and die.

This is because it is necessary to choose the right wire when decorating, and it should also be decided according to the power and wattage of the wire, so the thicker the better.

Because there is no way to hide the thicker wires. And the quality of the thick wire is actually not very good, so it is still necessary to choose some thin wires.

The thicker the wire, the better, you should find a ***, not that it looks thick and feels like it can be used for a long time.

The larger the wire diameter, the greater the current carried, which is the basic common sense of electricity! The larger the line used, the more you don't have to worry about various line failures caused by overload! In home improvement lines, many owners also believe that the larger the use of wires, the safer they are!

Not only does the owner think so, I also think so, except for mosquitoes, everything is big and good!

BV copper core wire.

In home decoration, the use of wire size should be more reasonable to choose is correct! The use of wires is large, which not only wastes money, but also increases the construction difficulty of hydropower transformation! If the wire is too large, the socket may not be installed, or the socket may be broken by the wire because the wire is too large and too hard!

The current house design has distributed the circuit very well, and the larger electricity consumption basically uses a separate circuit! The picture shows the indoor power distribution system design of a well-known real estate in a city! In home decoration, the size of the line can be referenced!

Ten or eight circuits in a house is already very normalized, not only the design of building electrical, but also the master of many hydropower renovations! For the design of the design institute, it is still worth learning!

In the home decoration of the socket diagram, although it is good to refer to the practices of others, you can also calculate the electricity consumption at home, and the reasonable use of wires is more cost-saving! However, it is recommended that you should use a square copper core wire at the minimum!

If you know the wattage of various household appliances, then you can calculate the electricity consumption like this:

The safe ampacities of wires per square (cross-sectional area of wires) are 8 amperes (generally copper core wires are 5-8 amperes), the rated voltage of household electricity is 220V, and the safe ampacity multiplied by the rated voltage is equal to the electric power, that is: 8AX220V=1760W

Then the power of the square wire is , 20ax220v=4400w

Can you have this number of lighting? Similarly: , 20ax220v=4400w

4x8=32a， 32ax220v=7040w

6x8=48a, 48ax220=10560w

The square number of copper core wires x 8** x voltage 220v = bearing wattage.

In this way to calculate household electricity, are you still worried about the size of the wires at home?

Home improvement circuit wires are not always better. It should meet the actual needs of household use. Excessive wire circuits can also cause safety accidents. At the same time, it is not conducive to the elimination of dangers and safety hazards.

The circuit wires of home decoration can be selected separately, for example, if the electricity consumption of the kitchen is relatively large, you can choose some thicker copper wires.

No, on the contrary, the larger the circuit wire, the more troublesome it is to use, and the quality is not too good. It is not recommended to use large ones.

Many people buy hardcover rooms, or all package them in a decoration company, and don't worry about it at all. However, circuit transformation and layout is the most important part of decoration, which is about our electrical safety. Nothing to understand.

It really doesn't make sense, right? In addition, some renovation companies know exactly that everyone is white, and they deliberately play tricks when decorating, and it is our owners who suffer in the end. When it comes to circuit modification, it is nothing more than distinguishing household circuits, choosing the size of wires, selecting switches, etc.

Today, the dean focused on the differentiation of household appliance circuits and the correct choice of wire size.

We want to buy 1 square millimeter wire, say 1 square, buy 4 square millimeter wire, say 4 square. Our general wires are 1 square, squared, squared, 4 square, 6 square and 10 square 6 kinds. More than 10 squares, we don't often use it, and we don't use it very often.

Unless you're in a factory, you're going to use a lot of high-power appliances. When buying wires, if you buy wires with small current capacity and connect wires with high power, the wires will heat up, and leakage and overload will easily occur, so the circuit will be damaged by burning electricity or wires. In this case, many people will think that the thicker the wire, the better.

Because it has a larger current carrying capacity. Because if you replace the wires at home with large square wires, you are not afraid of circuit tripping, overload, leakage, electric combustion, etc.

If you only consider the thickness of the wire, the thicker the better, but if we are "home renovation", we should consider it separately. When we buy wires, the store asks. How many wires are you going to buy?

The size in this actually refers to the cross-sectional area of the wire. The unit is millimeters squared, which is often referred to as "how many squares". For example, 1 square, 4 square.

What is the difference between wires that are squared? In fact, the main thing is the difference in the amount of current, the thicker the wire, the greater the current capacity. Typical home wires are 1 square, squared, squared, 4 squared, 6 squared, and 10 square 6 types.

Calculate the amount of current required for each circuit. Select the appropriate wires and switches according to the magnitude of the current. Before laying out the circuits, the household appliance circuits must be divided so that the wire size and switches for each circuit can be reasonably determined.

Generally speaking, there are four types of distribution box switches in my house: main switches, socket circuit switches, high-power circuit switches, and lighting circuit switches. Among them, the main switch is a circuit, the lighting switch is a circuit, the ordinary socket in the bedroom, living room, dining room and study is a circuit, the high-power socket is a circuit, and the kitchen and bathroom are a circuit.

There are six common types of wires: 1 square, square, square, 4 square, 6 square and 10 square. More than 10 square meters, we are not common, nor do we commonly use, unless you are engaged in factory production, need to use a large number of high-power electrical appliances. The difference between different square wires, the difference in the current carrying capacity, the larger the cross-sectional area (thicker), the greater the safe current carrying capacity of the wire.

The total power of lighting fixtures is relatively small, generally not more than 1000W, so the lighting circuit can choose a square copper core wire, of course not.

The voltage of our home is 220V, and the electrical power of different electrical appliances is different, according to the formula P=UI, we can accurately calculate the size of the current. For example, if a socket needs to be connected to an electric water heater, and its power is 4000W, then the current carrying capacity required by the circuit is 4000 220=, and the corresponding wire needs to be squared.

What size of wires are suitable for home decoration?

If we only talk about wires, it is true that thicker the better—the thicker the wire, the greater the current carrying capacity and the better the insulation. It is not easy to heat up, it is not easy to leak, and it is safer to use.

But when it comes to where it's used, you can't just consider the performance of the wire. For example, what we want to say here, "decoration wires", in addition to wires, also need to consider objective factors. In the decoration environment (home), the increase in the thickness of the wire will cause two drawbacks:

Associated costs increase.

It seems that 6 square copper wires are not much more expensive than 4 square copper wires. However, the increase in the number of wires will cause an increase in a series of costs.

The wire has become thicker, and the corresponding conduit has to be thicker; The grooving depth should be increased; The backfill depth should be increased; The size of the pipe clamp should be increased; The construction time needs to be extended - these are not only a matter of cost, but also a loss of floor height and time.

Reduced operability.

The thicker the wire, the more difficult it is to construct – in addition to the difficulty of slotting and burying the pipe, there are also difficulties in wiring and maintenance. As the wire becomes thicker, it will also become stiffer, and it is laborious to pull and die.

How thick the wires are used for decoration Choosing wires is more like choosing a pair of shoes for yourself - too big or too small is not good, the right is the best!

In the "Code for Electrical Design of Residential Buildings", it is clearly stipulated as follows: for a one-bedroom house below 60 (inclusive), 6 square copper wires are used for the main circuit; Square copper wires are used for lighting circuits; Ordinary socket circuits use square copper wires; The high-power socket circuit uses 4 square copper wires.

For other residences, 10 square copper wires are used in the main circuit; Both the lighting circuit and the ordinary socket circuit use square copper wires; The high-power socket uses 4 square copper wires.

This set of specifications was implemented in April 2012, which is relatively in line with the electricity needs of today's households, and most home renovations do the same.

There is no need to be too thick, kill the chicken and the knife, no matter how thick the line in your room is, he will die if the line enters the house, and it is not necessary to match the size of the line according to the demand for electricity in life.

No, it is best to be suitable, you see how many electrical appliances there are at home, how much power they add up, and then choose one that is larger than the total power.

If it is purely for the wire itself, then the thicker the wire, the better. Because the thicker the wire, the higher the safe current carrying capacity, there is no doubt about this. Because of the thick wire, its wire diameter is relatively large, but if it comes to the place of use, you can't just consider the performance of the wire.

For example, what we want to say here, "decoration wires", in addition to wires, also need to consider objective factors. In the decoration environment (family), the thickness of the wire increases In fact, when making the circuit, the thicker the wire, the better, as long as you do a good job of each load, there must be certain benefits to choosing the thick, but when installing, it will bring difficulties to the workers!

<> hydropower project in the decoration belongs to the concealed project, that is, the so-called line to be installed in the wall, in addition to the switchboard and some valves, the rest of the line is inconvenient for future maintenance, in general, ordinary sockets, bedroom air conditioning with the square is enough! Lighting or both! Living room air conditioner, kitchen socket, bathroom water heater with 4 square meters!

If the water heater and air conditioner are bought with a large amount of electricity, you can choose to use 6 square meters! If you just look at the wire, the thicker the better, the thicker the wire, the greater the current it will receive, but the higher it is. According to the power of the appliance, the right wire is the best choice, which can withstand the power of the appliance without spending much money and not wasting resources.

The first thing we see when buying wires is the appearance and certificate of wire, the certificate must have CCC certification mark on the wire, there must be CCC certification mark on the wire, wire and cable products are national compulsory safety certification products, and all production enterprises must obtain high-power electrical appliances produced by China Electrician. In order to prevent overloading, plugs are generally designed that do not allow you to plug in casually, and can only be plugged into the air conditioning socket. Wires below ten square meters, each square of safe current for five ampere calculation, that is, power is equal to voltage multiplied by current (p=u*i) below is the commonly used wire square safety load index at home, because household wires are copper wires and conduits, wires below ten square meters, each square of safe current for five ampere, that is, power is equal to voltage multiplied by current (p=u*i) below is the commonly used wire square safety load index at home, because household wires are copper wires and conduits, back to the point, The thickness of the wires depends on the total power of the electrical appliances, and there is also a department in the company, where the electrician calculates the power or the total amount of electrical equipment based on the mechanical equipment provided by the equipment department, and then declares and collects electrical accessories.
