How many kilowatts can 35 square bv copper wire hold up?


Single core current carrying capacity 180A, 380V motor y280m-2, 90kw, rated current 166a



What is the maximum power that the live wire 2.5 square copper core wire and the zero wire 1.5 square copper core wire can bear?
I installed the instant water heater, which means that the maximum power of the water heater can not exceed how many watts?
In addition, can you give me a formula to calculate the power? Thank you for your help! Thank you!


Which line is thin, which line shall prevail to calculate the power
1.5 square copper wire can generally withstand more than ten amperes, which is known by checking the safety ampacity meter
This depends on your cable laying environment, heat dissipation and service time
In principle, the temperature of the wire should not reach a certain value
If your 1.5 square wire can withstand 15A current, then the maximum power is 15 * 220 = 3300W = 3.3kw
