Family decoration using electrical wire specifications: 1.5mm, 2.5mm, 4.0mm.
The conventional applications of electric building wire as follows:
1): 1.5mm2--- lamps etc.;
2): 2.5mm2--- high-power electrical appliances, such as air conditioning, electric water heater etc.;
3): 4.0mm2--- large appliances, home line, or special occasions, such as air conditioner. The air condition is using 4.0mm2 wire master. I consulted a unit of electrical engineers, the answer is: safety wire power 2.5mm2 is at least 3.2KW. The master bedroom hanging air conditioner is 1.5p, the total power of =1.5*735=1102W. Even taking into account the hook starting current of air conditioner, 2.5mm2 wire is enough. Hydropower is responsible for any teacher in our home alone the two 4.0mm2 circuit (I'm in favor of), one of which is the living room air conditioner (3P), another is the kitchen meet: lighting, lampblack machine, gas water heater, disinfection cabinets, refrigerators, microwave ovens used at the same time. If the family bathroom electric water heater, toilet to recommend the separate 4.0mm2 circuit can satisfy toilet: electric water heater, Yuba, heating, lighting and other use.
BVV wire: the full name of copper conductor PVC insulated and sheathed round sheath wire, also known as light PVC sheath cable, commonly known as hard sheath line. The letter B represents the cloth wire, and the letter V represents the polyvinyl chloride in the plastic. There are signs of hard wire, copper core (single conductor common) said no symbol omitted. Structural specification: the difference between BVV and BV line is more than BVV BV sheath. Suitable for AC voltage 450/750V and below power equipment, household electrical appliances, instruments and equipment used in telecommunication cables. The wire core allowed working temperature of not more than +65. The nominal cross section from 0.75-10 square is divided into 0.75; 1; 1.5; 2.5; 4; 6; 10; seven specifications. Purpose: BVV hard sheath wire is suitable for AC voltage 450/750V and below power equipment, household electrical appliances, instrumentation and telecommunications equipment for wire and cable, but also used for electrical wiring.
