How to calculate the amount of wire?

The purchase of decoration building materials requires certain professional knowledge, otherwise it is difficult to control the quantity of decoration building materials. For example, wires are a kind of building materials that are very difficult to buy. When carrying out hydropower transformation, it involves the laying of many wires. The amount of wires is related to the division of household functional areas. Do you know how to calculate the amount of wire? The following is an introduction to the calculation method of wire consumption for netizens.

Let's first understand some common sense of electricity usage, and then continue to talk about:

1. Commonly used wire types: 1.5 square meters for lighting; 2.5 square meters for sockets; 4 square meters for high-power electrical appliances (air conditioners, electric water heaters, small kitchen treasures, integrated stoves, range hoods, etc.). High-power electrical appliances generally also use three-hole sockets (not the three-holes below the five-holes, but a single three-hole).

2. Basic knowledge of the circuit: The voltage can only be guaranteed to be consistent when connected in parallel, that is to say, each light or socket must be led out from the main switch.

Third, the socket generally needs three wires, and the lighting lamp needs two wires.

The above three points are the basis for calculating the amount of wire. ? The following is an introduction to the calculation method of wire consumption for netizens.

Next, I will formally talk about how to calculate the amount of wire:

Determine the number and location of sockets, lights and related power-consumption units in each functional area. For example, the number of lighting lamps: dining room, living room, master bedroom, second bedroom, kitchen, balcony, bathroom, total six, and then measure the distance from each lamp position to the main switch position near the entrance door, and the zero line fire line each One piece, that is, the distance multiplied by 2 is the length of the wire required for each lighting lamp. For example, the distance between the living room lamp and the total switch is 6 meters, and the required amount of wire for 1.5 square meters is 6*2=12 meters (*3 when counting sockets).

Factors that should be considered when determining the position of the socket: Generally speaking, there should be sockets where there is lighting, and it is best to consider setting more than two for each lighting position. There must be more than three main functional areas, such as kitchens and bathrooms. Needless to say, where there are TVs and electrical appliances, the most important thing is to consider uncertain factors such as mobile phone charging and computers. The living room generally has to consider ground insertion. , Electric water heater, small kitchen treasure, integrated stove, range hood, etc.) with 4 square meters of wire. High-power electrical appliances generally also use three-hole sockets (not the three-holes below the five-holes, but a single three-hole).

2. Basic knowledge of the circuit: The voltage can only be guaranteed to be consistent when connected in parallel.

Third, the socket generally needs three wires, and the lighting lamp needs two wires.

The above three points are the basis for calculating the amount of wire. ? The following is an introduction for netizens to calculate the amount of wire.

Pay attention to the wiring of special household appliances. Nowadays, water purification equipment has been popularized in many places. Regardless of whether it is installed or not, it is best to reserve sockets for water purifiers and drinking fountains. There are garbage disposal, audio and so on.

Giving up the network cable. Although the network cable itself is not expensive, the interface and panel add up to a considerable cost. Most families now use WIFI, and fiber optics are used in many places. Therefore, the network cable can basically be ignored.

Based on the above, the required amount of each type of wire is calculated separately. Adding 5-10 meters for each type of wire is the quantity you need to buy.
