How big is the square of the home wire? Usually when the circuit decoration is used more is the cable and wire, a lot of people think that the thin is the wire, the thick is the cable, in fact, is not accurate. Wire is composed of a few strands of flexible wire, cable is composed of a few or an insulation package, which is still very different, but the general use of cable home, usually industrial construction will be used. All you need for home decoration is wires. Some owners do not understand what the square of the wire means, then simply introduce, the so-called square of the wire is actually the size of the wire, so it is not clear?
If the house decoration should choose wire lighting 1.5 square meters of load power within 1500 watts, socket 2.5 square meters of load within 2500 watts, air conditioning high power electrical appliances 4 square meters of load within 3000 watts. These standards are national standard copper wire, decoration do not buy non – standard copper wire.
Now the housing into the cable is 10-15 square meters, can withstand 8KW-10KW power electrical appliances, and old housing aluminum wire is generally 2.5 square meters, can withstand the power of electrical appliances below 1500 watts, 85 years of old housing, meters often trip is wire short circuit and overload. With the water heater often trip is overloaded, the meter unit is ampere to calculate, 1000 watts run 1 hour of electricity. If the decoration if all change copper wire. The aluminum wire in front of the meter can be replaced. Be sure to change.
For example, the number of lights: restaurant 1, living room 1, master bedroom 1, second bedroom 1, kitchen 1, balcony 1, toilet 1 a total of 6, and then the position of each light to enter the door near the total switch position of the distance measured out, zero line fire line each one, that is, the distance multiplied by 2 is the length of each light required wire. For example, the living room lamp from the total distance is 6 meters, the required 1.5 square line is 6*2=12 meters (calculate the socket when *3).
Generally speaking, there should be a socket where there is lighting, and it is best to consider setting more than 2 per lighting position. Major functional areas, such as kitchens and toilets, should be set up at least three times. It goes without saying that where there are TVS and electrical appliances, the most important factors to consider are mobile phone charging, computers and other uncertain factors. The living room is generally considered to plug.
Now water purification equipment has been popular in many places, regardless of whether to install at present, it is best to reserve the outlet of water purifier and water dispenser. Then there is garbage disposal, stereo and so on.
Copper wire can carry 1-1.5 kilowatts per square, aluminum wire can carry 0.6-1 kilowatts per square. So one kilowatt appliance needs only one square of copper wire. In terms of current, copper wire can usually carry 3A to 5A current per square for short distances. Heat dissipation conditions are good for 5A/ square millimeter, not good for 3A/ square millimeter 1.5 square wire load is about 1.5 kilowatts.
Standard 2.5 square wires are commonly used in sockets. Some large appliances use more than 2.5 square meters of wire. In detail, we want to understand how much 2.5 square wire load and then see how much electrical appliances are in line with, this is the most scientific way.
4. Ordinary wires are usually used for house access cables and air conditioning cables. Four square wires are also necessary if you have a bath bar and an electric water heater. Usually 4 square wires can be used for central air conditioning, power connecting line, vertical air conditioning, socket line, decoration line, lighting line, water heater, into the home bus, hanging air conditioning, and so on.
Now that we know the quotation of 6 square wires and the calculation of the maximum load of 6 square wires, as well as the calculation of the maximum load of all wires, let’s take a look at where 6 square wires are usually used. It depends on the size of your appliances. If you use six square wires, the maximum load is 10 kilowatts. So if you purchase more than 10 kilowatts of electrical appliances, your home even if nothing, use the 10 kilowatts of electrical appliances are back trip, so 6 square wire use is very big, so from another aspect to give us to understand the use of 6 square wire.
