The light-emitting tube can be bright, but the brightness is low. This is not necessarily the case with gas-cooled light sources (somewhat similar to energy-saving lamps).
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.
In China, the normal residential power supply (that is, civil electricity) is 220V, which may be lower than 220V, so there will be a margin of error for the voltage in the design and manufacture of household appliances, as long as this is met, it is normal. The normal voltage in Japan is 110V.
The toilet should be alternating current, and it must be alternating current for convenience, so if you still use direct current, can it be convenient?
Absolutely, AC above 80 volts can be life-threatening.
