Three Phase Power Supplies

[Spark2019]

Hi I'm new to the forum & currently still learning the trade, would someone please be able to clear this up for me as I keep getting conflicting information, my understanding of three phase power supplies is, if you have a standard system in place say TPN supply & 3 x main cut out's, fused at 100 Amps then surly this give you 100 Amps per phase only, I think I'm wright in thinking this, any advise would be appreciated thanks in advance.

Welcome to the forums.

You are quite correct in your assumption. If the service fuses are 100A each, you will have 100A per phase available to you.

I'm surprised you've received conflicting information on such a basic question.

Perhaps, someone thinks that because L1 returns via L2, that the supply is doubled because of the two fuses?

Hi Sparky Chick.
Thanks a lot for your quick response, I'm still currently learning the trade, I new it was as simple as this, the lads where having a discussion on site & coming up with all sorts, which then made me question my self, as can get confusing sometimes with what people say thanks again.

quite simply, each phase has a 100A fuse, so each phase can handle 100A.

Have you been going through your phases,again?

no, but I'm going through the local Spar's stock of Old Peculier faster than they can get it in. apparently they only have 5 cases each week and I'm the only one that buys it.
