How many wires do you need for one living room, four rooms, one hundred square meters

Each house has a different design, and the demand for wires is also different, but based on the fact that each family has the same requirements for home appliances, what they want is probably the same. 100 square meters of house decoration wires with wire specifications red, blue, flower wire each a roll, square red, blue each a roll, 4 square red and blue each roll. The square flower wire is used as the grounding wire, the square is used as the lighting wire, the square is used as the socket wire, and the 4 square is used as the high-power socket wire such as the air conditioner.

That is to say, you have to buy at least 7 rolls of single thread. Basic knowledge of single-phase electricity: the relationship between power consumption, power, current, and voltage a

Kw. Hours, abbreviated as "degrees" b, power (p) unit: watts.

Abbreviated as watts (w) c, current (i) unit: amperes.

Abbreviated as ampere (a) d, voltage (u) unit: volts.

Referred to as volt (V), the household power supply is generally single-phase alternating current, with a voltage of 220 volts; The industrial power supply is three-phase alternating current with a voltage of 380 volts. e. Power = current voltage, i.e. p = u i f, power consumption = power consumption time, i.e. power consumption = p t. The unit of electricity consumption is kilowatt-hours, and 1 kilowatt-hour of electricity refers to the electricity consumption of 1000 watts of power for 1 hour.

The unit of power cord is square millimeter (mm2), which is divided into copper core wire and aluminum core wire. Wire load current value specified in the national standard (partial) Cross-sectional area of copper core mm24 mm26 mm2Allowable long-term current 16A 25A25 32A32A 40A diameter (mm) Since the electric water heater works for a short time, it is generally calculated based on the current that can be allowed to pass 8A 10A per 1 mm2 copper core wire. Under the same cross-sectional area conditions, the load current value of the copper core wire is compared with the aluminum core wire:

1, that is, the current load of the copper core wire is twice that of the aluminum core wire. After 2000, the circuit design is generally as follows: 6-10 mm2 inlet line, 2 mm lighting line, 4 mm 2 socket, 6 mm 2 special line for air conditioning.

Air switch. Air switches, also known as automatic switches, low-voltage circuit breakers. The principle is: when the working current exceeds the rated current, short circuit, voltage loss, etc., the circuit will be automatically cut off.

At present, the family uses the DZ series of air switches, and the common models are as follows: C16, C25, C32, C40, C60, C80, C100, C120 and other specifications, where C represents the trip current, that is, the starting current, for example, C32 means that the starting current is 32A, and the C32 is generally used for the installation of 6500W water heaters, and the C40 air is used for the installation of 7500W and 8500W water heaters.

There are two kinds of grounding facilities, one is working grounding, which is the grounding that connects the live part of the electrical appliance with the earth, such as three-phase electricity.

Grounding of the neutral wire at the low voltage point of the transformer; One is protective grounding, which is to prevent the insulation layer of electrical appliances from being damaged and making the shell live or other metal parts that are not charged and hurt people. The grounding wire must be driven deep into the earth to be considered qualified grounding.

Summary. The zero line is blue, 100 m x 3 rolls in three colors.

The wire used for air conditioning shall not be less than 4 square millimeters, 100 meters x 3 rolls, including 2 rolls of live wire. 100m x 2 rolls 2 colors.

The grounding wire is yellow and green two-color wire. Dicolor.

The socket wire is used in square millimeters, it is recommended that the fire wire is used in brown or red for a suite, and it is recommended to use 4 square millimeters or even more, square millimeters, common decoration.

The lighting line is 1 square to 1 square millimeter. Choose BVR or BVV BVVR type wires.

How many meters of wires do you need for a 150-square-meter building? Three bedrooms, one living room and one bathroom.

The university takes 500 meters.

500 meters is single-line or double-line 500 meters, and how many micrometers are for each model.

The zero line is blue, 100 meters x 3 rolls The three-color air conditioning wire shall not be less than 4 square millimeters, 100 meters x 3 rolls, of which the live wire is 2 rolls. 100m x 2 rolls 2-color grounding wire is yellow and green two-color wire. The wire used for the two-base color destroyer socket is selected in square millimeters, and it is recommended that the fire wire is used in brown or red for a suite, and it is recommended to use 4 square millimeters or even more, square millimeters, common decoration.

Lighting line ruler can be used for 1 square to square millimeter dilemma. Choose BVR or BVV BVVR type wires.

Hope it helps.

Satisfied with my service Give a thumbs up and thank you.

Is this all single-line?

Yes. Is it necessary to multiply double the double line?

It is not used, it can be doubled, and the high-power electrical appliances are doubled, and the low-power electrical appliances are not used, which saves costs.

Hopefully, okay, thank you.

Dear, you're welcome to be satisfied with my service Give a thumbs up and kneel thanks.

Summary. Hello dear . How many wires do you need for the renovation of a three-bedroom house:

The renovation of a three-bedroom house requires about 500 meters of wires. But this is not absolutely accurate, because the specific amount depends on the method of wiring by the plumber, and the amount of reserved sockets also determines the amount of wires. If you want to analyze specific problems, I hope mine will be useful to you.

How many rolls do you need for each of the flat, flat, and four-flat ones?

Flat 3 rolls, flat 2 rolls. I hope my answer can help you.

About 130, about 80-100, your home, this ** within the whole problem is no problem.

Three-bedroom, two-living room and two-bathroom house, the general construction area is about 130 square meters, with square meters of sockets, air conditioning lines should be nearly 800 meters, to buy 900 meters is enough, excluding lighting lines, such as lighting lines are also used to add another 400 meters!

Summary. At least three coils of wire, one of which must be blue, as the zero wire, a yellow-green two-color wire, is the grounding wire, and the other can be any of the three colors of yellow, green, and red, about 700 pieces. Also, there is the electric conduit, about seventy or eighty meters.

There are at least twenty or thirty sockets, about three or four hundred yuan, and ten switches, about 100 yuan. In addition, you need some accessories such as adhesive tape, screws, etc. About 100 yuan The biggest expense is the lighting, the cheap two or three hundred, the expensive thousands, it depends on how much money you buy.
