Hi Fella's Me Again
Had the sparky over and everything tested out alright with the megger' he's coming back to play with the powerboard, he's talking about running a new circuit of up 6mm cable and 40amp C.B.
What I am running at the moment is a 20amp CB at the house through 50/60 mts of 10 mm cable to a power board in shed with 20amp CB and 40amp ELCB with 2.5 mm cable to 10amp GPO and we have 236 volts at GPO .
The ELCB will have to be upgraded to a VFD friendly one, the old one could be damaged from the welder triping it also.
Could you guys please advise on the circuit size I have or what you are using successfully on your VFD's, any input would be a big help.
THANKS
Paul
