How to calculate the wires used for home decoration

Observe the copper core of the wire, the gloss is good, the yellow is reddish is high-quality copper, and the yellow white and shiny is brass, low-quality copper. Hydropower engineering is a very important part of home renovation. The necessary factor for the quality assurance of hydropower projects is that the quality of materials must be passed.

Generally speaking, if the semi-package is repaired, the wires, waterproofing and other materials are purchased by the foreman or the decoration company, but as the owner, at least you must know how to judge the quality of the materials. In addition to wires, decoration and electricity-related need to purchase air switches, circuit breakers, strong current boxes, switch sockets, ceiling lights, etc. Under the same brand model, the soft wire is twice that of the hard wire....

1. Residential buildings (about 100 square meters of houses, all the old lines are replaced with new lines), wires per square meter: about meters; There is no formula for this, it is the experience summed up in the daily construction cost, because most of the residential buildings are similar in the design of electricity.

Square a house, 300 meters of line is not enough, unless you are not all replaced with new lines.

3. I don't know how your company's electrician told you, if he is not this data, then what he told you is wrong.

If the copper core sheathed wire (BVVB) is used to be surface-mounted or walked in the outer trunking:

How to calculate the amount of home decoration wires.

If you use copper core single strand wire (BV) or BVR: hidden in the ground or inside the wall:

How to calculate the amount of home decoration wires.

Description: The wire is used for the light line, the wire is used for the switch socket, the 4mm2 wire is used for the home line and the air conditioner and other high-power electrical appliances, and the two-color ground wire is used for the leakage protection of the electrical appliances.

The above is only the recommended dosage of 100mm2 house, and the actual dosage should be adjusted accordingly according to the size of the house area and the number of lamps, electrical appliances, sockets, and air conditioners.

At present, the new house decoration generally adopts copper core single-strand wire or copper-core multi-strand wire (the amount is consistent with the copper-core single-strand wire) casing laid in the wall; The sheath line is generally laid outside the wall, and now it is mostly used in rural areas or old house decoration, and the sheath line is rarely used in the decoration of new houses.

It's hard to say clearly, but the layout of the wiring has a big impact. All of them only put one main line is the most provincial, and it may take 3 laps. , one circle each, main line socket, lighting socket, lighting ground wire.

It can bring up to 2 hang-ups, and do not turn on other high-power electrical appliances.

Lines can be used in parallel.

To be accurate, draw the line position with a ruler first, and then add 15%.

Three or four hundred in two days.

The wire costs about 400 yuan, the switch socket is about 200, and the labor is about 300-400.

Supplementary question (it should be asked): This room is asked to budget professional or electrical, hardcover professional engineer who knows a little bit of budget to calculate, how many meters of square and 4 square wires are needed, plus artificial accessories, how much silver is needed? Thank you!!!

To calculate the amount of decoration wires used, you can do so by following these steps:

1.Determine the type of wire: Start by determining the type of wire you need to use, such as single, double, or multi-conductor wire. Different types of wires may be required for different uses and electrical loads.

2.Determine the wire specification: Choose the appropriate wire size according to your decoration needs and electrical load. Wire specifications are usually expressed in conductor cross-sectional area (in square millimeters), e.g., etc.

3.Measure Line Length: Measure the length of each line that requires a wire cover. This includes the distance from an electrical outlet to equipment such as lights, switches, sockets, etc.

4.Consider circuits and branches: If you need to lay out circuits or branches, consider adding up the length of the wires and making sure to reserve enough wire lengths to connect the individual devices.

5.Add some margin: In order to avoid the situation of insufficient wires, it is recommended to add some additional wire length to the calculation result as a margin. In general, an extra length of 10% to 20% is a reasonable estimate.

6.Calculate Total Usage: Add up the lengths of all the lines and add margins to get the total wire usage.

Please note that the above steps provide a rough calculation, but the exact amount of wire used will also depend on your specific needs and installation requirements. To ensure accuracy, it is advisable to consult with a professional electrician or electrical engineer who can provide more detailed and precise calculation recommendations depending on your specific situation.

You'll want to determine the distance from the doorway to the farthest location of each functional area. Measure the above distances;

2.Determine the number of lamps in each functional area, the number of sockets in each functional area, and the number of high-power electrical appliances in each functional area;

3.Calculation, Wire Length, Calculate Wire Length, 4mm Wire Length;

4.Finally, note that if it is a house with 3 bedrooms, 2 living rooms, 2 bathrooms, 1 kitchen and 1 balcony, the real data above is 12 meters, 12 meters, 15 meters, 7 meters, 4 meters, 12 meters, 4 meters, 6 meters, 15 meters, 0 meters, 8 meters, if the number of lights in each functional area is 1, the number of sockets in each functional area is 2, and the number of high-power electrical appliances in each functional area is 1.

Then according to the formula: the line needs 290 meters (within 3 rolls), it needs 690 meters (more than 7 rolls), 4mm needs 381 meters (4 rolls), ** wire, cable and network cable can be calculated.

Interior decoration is generally.

The wires are used for light lines, the wires are used for switch sockets, and the 4mm2 wires are used for high-power appliances such as air conditioners or kitchens.

10mm2 wire is used for the incoming wire.

If you need to use high-power appliances for the socket in your home, you can use four square wires or a larger core depending on the load.

When we go to buy wires, we must first calculate the amount of wires used at home, so that we can buy enough wires back, otherwise we will have to buy them again when the time comes, which is too troublesome. And buying too much at once will cause waste, let's take a look at Fengyin to see how to calculate the amount of home improvement wires.

First, you need to determine the farthest distance from the doorway to each functional area (master bedroom, second bedroom, children's room, living room, dining room, master bathroom, guest bathroom, kitchen, balcony, hallway). Measure the above distance, there are: a meter, b meter, c meter, d meter, e meter, f meter, g meter, h meter, i meter, k meter a total of 11 results.

Then you determine the number of lights in each functional area (the same kind of auxiliary lamp in each functional area is counted as one), the number of sockets in each functional area, and the number of high-power electrical appliances in each functional area (not represented by 0).

Calculate the length of wires as: (A+5m) multiplied by the number of lights in the master bedroom; (b+5m) the number of lights in the sub-horizontal area; (c+5 meters) the number of lying lights; (d+5m) the number of lights in the passenger hall; (e+5m) by the number of lights in the dining room; (f+5 m) by the number of main lights; (g+5m) the number of passenger lights; (h+5m) by the number of kitchen lights; (i+5m) by the number of balcony lights; (k+5m) by the number of corridor lights; The sum of the above results is multiplied by 2.

The length of the wires is calculated as: (A+2m) multiplied by the number of sockets in the master bedroom; (A+2m) by the number of sockets in the master bedroom; (B+2m) the number of sockets in the second bedroom; (C+2 meters) the number of sockets in the bed; (d+2m) the number of sockets in the passenger hall; (e+2 meters) by the number of outlets in the restaurant; (f+2 m) by the number of sockets in the main bathroom; (g+2m) the number of passenger toilet sockets; (h+2m) by the number of kitchen outlets; (i+2 m) by the number of balcony sockets; (k+2m) by the number of sockets in the corridor; The sum of the results of the previous count is multiplied by 3.

4mm wire length is; (A+4m) the number of high-power electrical appliances in the master bedroom; (b + 4 m) the number of high-power electrical appliances in the second bedroom; (C+4 meters) the number of high-power electrical appliances lying on the child; (d+4 m) the number of high-power electrical appliances in the passenger hall; (e+3 meters) by the number of high-power electrical appliances in the restaurant; (f+3 m) the number of high-power electrical appliances in the main bathroom; (g+3 meters) the number of high-power electrical appliances for passengers; (h+3 m) by the number of high-power appliances in the kitchen; (i+2 meters) the number of high-power electrical appliances by balcony; (k+2 m) the number of high-power electrical appliances by corridor; The sum of the above is multiplied by 3.

3 bedrooms, 2 living rooms, 2 bathrooms, 1 kitchen, 1 balcony house The above real information is 12 meters 12 meters 15 meters 7 meters 4 meters 12 meters 4 meters 6 meters 15 meters 0 meters 8 meters, if the number of lights in each functional area is 1, the number of sockets in each functional area is 2 The number of high-power electrical appliances in each functional area is 1 Then according to the formula: the line needs 290 meters (within 3 volumes), 690 meters (more than 7 volumes), 4mm needs 381 meters (4 volumes), ** wire, cable and network cable can be calculated, This information should be quite accurate, and there is room for improvement.
