380 is also used for catering equipment, with good insulation, no leakage, and the same safety. 220 electricity, equipment leakage is as dangerous.
Regardless of 220 or 380, after leakage, the voltage of the shell to the ground is 220
It must be very dangerous, and it is recommended that if there is a leakage in the kitchen, find a professional to repair it as soon as possible.
This is indeed a bit dangerous, after all, sometimes there will be a question about the power equipment. >>>More
Normal use is not dangerous, illegal operation is very dangerous.
If the complete three-phase balance, 300A*380V*, greater than 130KW, yes, but if the three-phase is unbalanced, the total power required should be calculated by the maximum one-phase current, and it is easy to overload the difference by such a point.
No, 1 has a ground wire, 2. Families don't have circuit breakers, and leakage will jump.
