Three phase query.

[gm5656]

Hi all,can anyone help on this one?Three phase 70kva,Lawson mf100a at mains/meter and Lawson tcp100 at switch/board.Can i run 80 or so amps per phase with possible start surge of 90 amps briefly,or is this pushing things a little.

Newbie!,any replies gratefully received.

Thanks Gaz.

Welcome GM , I'd say you'd be fine with that, not familar with the phrase tcp 100 TBH.

HRC fuses will carry start up currents with no problem.

Cheers Deke, the Tcp100a is the Lawson equivalent of the 100amp SD5-HRC.Happy days,thanks again.
