Everyone in the renovation of the decoration of the way to choose the most part of the half-package, then the budget control of all kinds of decoration materials on their own grasp. When the hydropower is reformed, the electrician will tell you to buy electric wires. If you buy less, you have to make up for it. There is not much time to delay the construction. If you buy it, the return is also troublesome, and the return may detract from part of the price. It would be great if the number of wires bought was not much. How can I know the need for your home decoration wire usage?
First of all, to understand some of the common sense of electricity, and then continue to talk about:
First, the use of commonly used wire types of objects: lights generally use 1.5 square; socket with 2.5 square; high-power appliances (air conditioners, electric water heaters, kitchen Po, integrated stove, hood, etc.) with 4 square wire. High-power electrical appliances also generally use three-hole sockets (not the three holes below the five holes, which are three separate holes).
Second, the basic knowledge of the circuit: When the voltage is connected in parallel, it can be ensured to be consistent, that is, each lamp or socket must be led out from the main switch.
Third, sockets generally require three wires, and lights require two wires.
The above three points are the basis for calculating the amount of wire used.
Then formally talk about how to calculate the amount of wire usage:
Determine the number and location of outlets, lights, and associated power units in each functional area. For example, the number of lights: restaurant 1, living room 1, master bedroom 1, second bedroom 1, kitchen 1, balcony 1, bathroom 1 total 6, and then each lamp position to the total switch position near the entrance door Measured, one of the zero line FireWire, that is, the distance multiplied by 2 is the length of wire required for each lamp. For example, the distance from the living room light to the total level is 6 meters, and the required line quantity for 1.5 squares is 6*2=12 meters (*3 when counting sockets).
The factors that should be taken into account when determining the location of the socket: Generally speaking, there should be a socket in the place where there is lighting, and it is better to consider setting more than two for each lighting position. The main functional areas, such as kitchens, toilets, etc. should be set more than three. It is not necessary to say that there are televisions and electrical appliances. The most important thing is to consider the uncertain factors such as mobile phone charging and computers. The living room is also generally considered to be inserted.
Pay attention to the use of special household appliances. Nowadays, the water purification equipment has been popularized in many places. Whether it is necessary to install it or not, it is better to reserve a socket for water purifiers and drinking fountains. There is garbage disposal, audio and so on.
The abandoned network cable. Although the network cable itself is not expensive, the addition of interfaces and panels is not a small cost. Most families now use WIFI. And many places use fiber. Therefore, this piece of network cable can basically not be considered.
In summary, the required amount of each type of wire is calculated. Adding 5-10 meters to each type of wire is the amount you need to buy.
