Household circuit box? The difference between a circuit box and a distribution box

For a family, a 64A switch is sufficient.

In a single-phase circuit, one kilowatt of power corresponds to a current of 4,5 A, and 64 A corresponds to a dozen kilowatts.

Almost all high-power electrical appliances at home are heating appliances, such as electric water heaters in the bathroom, electric baking pans in the kitchen, kitchen treasures, drinking water heaters, electric heaters used in winter, and air conditioners for heating. The power of these appliances is about 1kw-2kw, and the maximum will not exceed 3kw. Can you calculate for yourself that the total power will exceed 10kw.

But don't forget that some appliances are used seasonally, some work intermittently, and some are never used at the same time.

The calculation of household electrical power, which generally takes into account the total power that is likely to work at the same time, usually does not reach 10kw.

The capacity of the general family is enough, it is recommended to divide the room, the bathroom and the kitchen are separated and independent, it is recommended that the main gate should not be used with leakage protection, as soon as there are some small leaks, jump the main gate, it is dark at night, you will be at a loss, or the key bathroom, the kitchen is better to use the leakage protection independently, the grounding wire must be in place, this is the advice of the old electrician.

According to your description, the household air allocation is sufficient, that is, if there are many outlets, you can divide them into 1 group of 20a. For example, the bathroom or kitchen can be separated.

It mainly depends on the power of electrical appliances at home.

,..Basically, you can. It is recommended that the air conditioner should be 1p32 amperes a little better, after all, the air conditioner has a large starting power.

The socket should be 2p, it is best to separate the kitchen, because the kitchen electricity power is particularly large, and it is better to have 32 amps, and then the room socket is 1p20 amps. Lighting with 1p20 amps. If there is an outdoor (outdoor), it should also be separated, and the power supply of the bathroom should also be separated separately to improve safety, so that in case of leakage, it can be turned off to avoid the leakage switch tripping (temporary use)...FYI!

Summary. 1.Advantages are different 2

Meter box: completely solve the personal accident caused by poor grounding of the box and foreign body lapping; Low comprehensive cost; It can effectively resist the impact of external forces; Combustion at high temperatures does not produce asphyxiating gases. 3.

Distribution box: small size, easy installation, special technical performance, fixed position, unique configuration function, not limited by the site 4The use is different5

Meter box: The meter box is generally used as a cable branch box, low-voltage distribution box, pump control box, communication device cabinet, street lamp and traffic light control box, multi-function metering box According to your description, one or more meters are installed in the meter box, and the distribution box is in addition to the meter, there are multiple switches, knife switches and other control appliances and multiple output lines. It is used to control the on/off of each circuit.

Can you tell us more about that?

1) The distribution box is a small power distribution box, which contains a power switch and a safety device. The structure is relatively simple, and it is mostly used for terminal power distribution. Distribution box is the last level of power distribution facilities in the power supply system, a distribution box can be a power supply inlet and a plurality of power supply output pins in the circuit, from the distribution box to lead out the power supply output circuit to each electrical load, because the size of the distribution box is small, can not be put into the large distribution equipment, so the capacity of the distribution box is not large, generally 4-8 small loads with a distribution box, the distribution of the loss of the electric box is arranged in the center of the power supply load, with a cable or wire to send electricity to the load.

1. All have to admit that the national standard regulations on indoor distribution boxes have not kept up with the pace of the times - I believe that in the near future, the national standard will be upgraded.

However, until then, the indoor distribution boxes equipped by developers were still the current standard. As a result, there are many users who want to transform the distribution box of their home during decoration and turn it into a safer and more functional product. So, how should the household distribution box be designed?

Let's say it step by step.

Determine the number of loops.

First of all, we need to figure out how many switches are needed in the distribution box of our home

1.Count the number of rooms first to determine the number of socket circuits: for example, the three-bedroom, two-living room, kitchen and bathroom apartment has a total of 7 rooms, then we need 7 socket circuits.

On top of that, if there is a room that is very small, we can merge it into an adjacent room. For example, if the dining room is very small, we can merge the dining room into the adjacent living room – only 6 socket circuits are needed.

Note: No matter how small the bathroom is, it must be a separate circuit and cannot be combined with other rooms.

2.Use one circuit for each appliance with more than 3000W, and one circuit for every two air conditioners hanging up – they are collectively known as high-power socket circuits.

3 bedrooms and 2 living rooms, 3 air conditioners (2 circuits, 1 circuit) and 1 electric water heater (1 circuit) are required. A total of 4 high-power circuits are required.

3.The number of lighting circuits is generally bounded by a construction area of 180 - if it does not exceed 180, 1 circuit is used; More than 180, 2 circuits are used; After that, every 180, add one loop.

Not very standard. According to the standard specification, at least the name of the device under control must be written.

This can only be the case, now the circuit has been changed after the home decoration, and the decoration is marked after the decoration.
