Hi all
I've put in a new radial circuit for my 3hp compressor but every time I fire it up the MCB trips immediately. I've tried with a 16A and 20A MCB but get the same result. The compressor was working fine at my old house so I'm assuming it's down to the install and not the compressor.
The circuit is a 60cm run of 6mm cable from the CU and terminates at a 16A socket. The MCB's I've tried are both Type B and I suspect that may be the issue.
If I try a Type C MCB is there any issue with using a 32A one or should I go back down to 16A ? My local stockist hasn't got any 20A ones !
Cheers
