Is there a particular reason you need to know about food factory LV supplies?

It would help if we knew where abouts in the word you are. The two main codes are NEC (Americas) or IEC (Europe and much of Asia). Each have their own set of codes or regulations.

Engineering work in the food industry is difficult due to hygiene requirements. For some reason customers don’t like nuts and bolts in their food. I’ve worked in the food industry twice as an engineering supervisor, I would never go back to it.

For factories where food beverages and plastics are produced, the intake of the power supply is 11kV (some other country may not the same) and thru a transformer they are step down to 3 phase 433V/50hz but in this case, in America or other Europe country it may be 3 phase 480V/60hz. (correct me if I am wrong) and the single phase is 240V/50hz and in America or other Europe country it may used to say 2 hot wire at 110v or 220v.

Equipment are either operated on 3 phase system at 480V/60hz or 2 hot wire system (Single phase system). It all depend upon the equipment design and operating voltage requirement. For control system, such as signal relay, control relays, sensor, limit switch, level indicator, PLC, contactor and other control parts may use 24Vdc/ac, 48Vdc, 110Vac.

In generally, all the equipment and machines electrical motor are operated with 3 phase system but there is also some of the electrical induction motor are operated by single phase system.

Transformer sizing are depend upon the total factory equipment loading and the total power requirement. Some factory may have a very big transformer and some factory may have a smaller transformer.

This is just a general information only.
