Welcome to ElectriciansForums.net - The American Electrical Advice Forum

Hi all,

Got an interesting generator related issue here………………. I’m currently helping a friend with a 100KVA geni and I’m after some advice. I’m trying to work out what the maximum current draw would be…………..

So if O\P Amps = KVA / (O\P Volt / 1000) = 100/(240/1000) = 416.66 Amps

But as it’s a 3-phase geni should I be using 415V and not 240V??

The reason I want to know is because I want to add a supply breaker to each of the x3 distribution panels. So assuming my above calculation is correct that’s 138.88Amps per phase or 100amp to be safe.

Many thanks
