Wire section the diameter of the selection and household appliances power relations
Wire section the diameter of the selection and household appliances power relations Usually said lighting 1.5, ordinary switch socket 2.5, air conditioning switch 4 (units are was), what is it? Per unit of area, copper wire carrying current: copper wire is about 5-8 Ann/was, aluminum wire about 3 to 5 Ann/was the, the numerical why is a interval? Because the use of the temperature, pressure will influence the wire current size, because current is in essence a kind of molecular movement. The practical application of copper choose 6 Ann/was the can, but still tend to smaller numerical 5 Ann/was, for electrical things or conservative as well. Physical public: P = UI, P: power (KW), U: voltage (v), I: current (Ann). 1 horse is about equal to the air conditioning 0.735 KW, then the air conditioning socket wires carrying 735 ÷ 220 we 3.34 Ann's current, per unit of area, according to the current copper wire carrying six Ann/was, so a piece of copper wire most above 2.5 diameter and 4 1 series of horse air conditioning, which, of course, is a theory of value, the actual engineering is not so much of the series, at most is also at the same time series two. The rest of the appliances can so on, most of the high power electric socket with 4 was the best or the wire, according to security reserve 25% to calculate, 4 was the wires can carry 4 x 6 x 220 x 75% = 3960 w, also is nearly 4 kw electrical appliances.
