How many squares of domestic electric wire? Decoration style, decoration budget, although these are very important, but after all, it is the bright side of things, how are good to say, but for those after the renovation of the owners simply invisible places, such as electrical wiring such accessories, should pay more attention, after all, if the accident occurs because of leakage or power outage, it is definitely not the owners want to see. With the continuous improvement in the quality of life of the owners, a variety of new household appliances have come into being, so households use electricity more than before, so the choice of household electrical wiring should be doubly careful.
The regular size of the household electrical wire
We often hear how many square wire that refers to the size of the wire, the common size of 1.5 square, 2.5 square, 4 square, 6 square, 10 square these kinds of. Wire square is square millimeters, refers to the size of the cross-sectional area of the wire conductor.
How many squares of domestic electric wire:
1, each computer power consumption of about 200-300w, then 10 computers need a 2.5 square millimeter copper-core wire power supply, or a fire may occur.
2, large 3 horsepower air conditioners consume about 3000w, then 1 air conditioner needs a separate 2.5 square millimeter copper-core wire power supply.
3, the housing incoming wire is now generally 4 square millimeters of copper wire, therefore, the simultaneous opening of household appliances shall not exceed 25a, someone will replace the wire in the house to 6 square millimeters of copper wire is useless, because the wire into the meter is 4 square millimeters.
4, early housing incoming wire is generally 2.5 square millimeter aluminum wire, therefore, the simultaneous opening of household appliances shall not exceed 13a
5, more power consumption of household appliances are: air conditioning 5a, electric water heater 10a, microwave oven 4a, rice cooker 4a, dishwasher 8a, washing machine with drying function 10a, electric water boiler 4a in the power supply caused by fire, 90% is due to the heat of the joint, so all the joints to be welded, can not be welded contact devices 5 to 10 years must be replaced .
Master the wire purchase method
1, see the package has a complete certificate of compliance, the certificate should include specifications, the implementation of the scale, rated voltage, length, date, factory name and address and other complete information. See if there is a Chinese national compulsory product certification “CCC” and production license number; see if there is a quality system certification; see if the certificate of conformity is standardized; see if the wire is printed with the trademark, specifications, voltage, etc.
2, in the relevant scale, the length of the wire error can not exceed 2%, the cross-sectional diameter can not exceed 0.02%, but there is a large number of short in the length of the market, the phenomenon of falsification in the cross-section.
3, qualified copper core wire copper core should be purple-red, shiny, soft to the touch. And shoddy copper core wire copper core is purple, yellowish or white.
4, shoddy wire insulation layer looks as if it is thick, in fact, most of them are made of recycled plastic, as long as the slightest squeeze, extrusion will become white, and powder fall off.
5, good quality wire, generally within the delineated weight range. Such as the commonly used cross-sectional area of 1.5mm2 plastic insulated single-strand copper core wire, the weight of 1.8 to 1.9kg per 100m.
6, the best brands, the quality of course, superior. Therefore, when buying, it is best to choose a reputable brand products. Because only big brands will cherish their brand image and brand value, will not do false propaganda, and pay more attention to quality and service.
