Anonymous users2024-01-24The equipment in the kitchen, usually not used at the same time, what you say 100 kilowatts is the installation capacity, but when choosing the cable, it is not based on the rated capacity of the equipment, but according to the calculation of capacity, that is, 100 kilowatts should be a simultaneous coefficient, and each equipment should consider the need coefficient, so as to be accurate, so that the cable selection is not too large. Basically, each equipment adopts the need coefficient of the left and right, and the coefficient can be adopted at the same time, and the rated capacity of the largest equipment can not be greater than the calculated load, and if it is greater than it, the calculated load should be re-corrected. Then it's time to choose the cable.
The larger the number of units, the smaller the capacity of a single unit, and the coefficient can be appropriately reduced. Because I don't see the list of your devices, I'm sorry I can't provide a specific solution.

For 380V three-phase 140 kW power consumption, a 400A circuit breaker is required for the main switch, but each branch and each individual device should be equipped with a separate switch, not just one main switch.
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
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.
The total number of three phases is 280KW, and the current per phase is 420A, so use a 185 or 240 cable. Considering that the cables on the market have different degrees of shrinkage, it is recommended to use 240. Basis:
5 hp = 735 x 5 = 3675 watts. So you can install up to ten.
