Four air-conditioning, two electric water heaters at the same time need to use the number of square wires more
Air conditioning according to the calculation of 1.. the water heater each calculated by 2000W, respectively, to discuss: 1) air conditioning and heating and heating is not open and with two water heaters at the same time the current is: (1100 × 4 +2000 × 2) ÷ 220 ≈ 38A At this time the bus should use at least 6 square copper wire; 2) air conditioning to open the auxiliary heating and heating with two water heaters at the same time the current is: 2000 × 6 ÷ 220 ≈ 55A at this time the bus should use at least 10 square copper wire. So from the home point of view, you should choose is 10 square copper wire. Supplement, household wire diameter selection and power correspondence
I see really tragedy, the bullet is useless, I used to install the monitor used. It is not easy to wear straight pipe, let alone have bent. Bullet is a wire wrapped in a layer of plastic, can only wear straight pipe, his greatest benefit can be used repeatedly, will not cause waste. In addition to this I think that basically no use. Your new house as long as the pipe is not blocked, are good threading, buy ten meters of steel wire to play a hook were two to wear, from a stir, bring out another wire, and finally in the hanging line. If you can not solve, you find water utility bar.
27KW * 1.5A / KW = 40.5A (per phase current) 36KW * 1.5A / KW = 54A (each phase current) 10 square line maximum withstand current 40A, switch to 3 * 16 +2 * 10 cable, With M1-63A / . contactor replaced by CJX2-. with two 10 square lines and parallel line, 25-ping line of safe current in the 80 or so, with two small, water heater lead or replaced It, if only temporary can also be used for a long time or for a washing machine and the energy of the energy-saving lamps add up to 200 watts, can be ignored.
Rated current estimated at about 50A, plus the use of coefficients, etc., open the contactor and so should be in accordance with the 80A level to select the wire for 16 square or more
