32A? Properly you should use 4mm^2 with that.
Or make it a very short ring with 2.5mm^2
We've established upthread that the 2.5^2 is short enough.
Not short enough for a C type 32A MCB on a TN-S supply that is at the
upper limits of it's maximum allowed Zs.
Sorry I missed we'd changed from type B to type C. That makes a
dfference I suppose? With my limited knowledge I think I just know
that ordinary circuits will be all right with 20A type B and if I want
anything more unusual I'll ask.
