First time in industrial electrics so any help would be appreciated.
What voltage figure is used for cable calcs, 400 or 415. I am installing a welder on a 32a 3 phase socket. MCB is type c 32 amp, length of run is 30 metres. Owner assures me it is purely for the welder but I know engineers will plug in anything that fits so must go to 32 amp load. Cable will be surface mounted 5 core swa. If I have missed anything please let me know.
Many thanks
