My family always switch zero line insurance burning is going on?
We allowed range of voltage fluctuation is plus or minus 5%, which is no more than 231V, if the insurance for aluminum wire are burned, is not your electricity load is too large, should be avoided while using high power electric appliances. In order to ensure the safety of family property, please look for professional electrician as soon as possible!
Are you sure the burning line is zero? I can responsibly tell you: zero line is not insured! Because we use voltage is 220V, once the breakage of zero line (fuse) then the voltage by line voltage (voltage between the live wire and zero line) to phase voltage (voltage between two FireWire), which is the 220V voltage multiplied by the square root of 3 times = 380V
