I have seen in books that says DOL starters are used up to 50 hp(roughly 37 kw). In my project in singapore, 19 pumps of 160 kw are all start by DOL.(May not start all in one time). It is equal to 214 hp each.

i have been tasked with a design of protection, metering and control(PMC) relay panel extension to accommodate all PMC relays.There is an already existing panel where this one will be built.What are the design aspects for this kind of project? thank you.
