duncan, you need to know the current capacity of that 1.5mm cable feeding the motor. assuming it's around 16A, then your MCB needs to be rated less than 16A. bearing in mind that the MCB protects the cable. you would need to use a type C to handle the start up current without tripping, so a 10A would seem appropriate. another point to note, if you are not au fait with 3 phase, is that if the motor runs the wrong way you have your phase rotation incorrect and would then neede to swap any 2 phases at the motor isolator.
Cheers Telectrix. I was aware re turning the phases, thanks - gleaned that from today's research
10 amp was my own first thought, but Darkwood suggests 20amp and I think I see where he's coming from in the info he posted in #30.
Darkwood also asked for a pic of the plate and I did take one, just about to get it off my phone and post it here.
Thanks again.
