Anonymous users2024-01-23It is better to use a transformer for a current of nearly 80A. In terms of wires, 10 square wires are sufficient. If the front-end voltage headroom is not large. The wire diameter can be larger.

Such a large load can not use a power supply, should be based on the actual situation of multiple power supply, one is convenient maintenance of a power outage has little impact on other equipment, and then to reduce the failure rate, and there is a lot of cost reduction, because the thicker the single strand wire diameter, the smaller the current carrying capacity per unit area.
A 100A switch only carries a device of 22 kilowatts at most, the reason is that 100A * 220V = 22000 watts. You need a 300A switch to carry a 60 kW appliance.
It can be used, if the power supply distance is not very far (50m), there is no problem, there will be no burning, short circuit, there is no problem with the copper core wire, and 4mm if the aluminum core is used
100 kW kitchen.
If 220VAC is used, the current is about 455A, considering the starting current of the device, a 160mm2 copper core cable should be used. >>>More
Electrical appliances will produce electromagnetic waves with radiation, which is much less safe than mobile phones. It should be kilowatts = 1200 watts, 12 kilowatts = 12000 watts, please accept.
