Why do you want to use such an ancient bit of kit?
In another word - negative. You should not put heavier wire or two wires in one carrier as the contacts of the carrier are only rated for the current stated and may overheat badly with the extra load. Nor may you connect two carriers together each with wire to their maximum rating, as two thermally separate fuse elements do not behave like one element of double the rating, and there is a massive latent hazard of the circuit not being correctly isolated.
I have seen this done once, I got a belt from it and it eventually burnt out. Please don't repeat this yourself.
Yes cheers for that .You'll probably need a Type C MCB for the welder circuit, and then bear in mind the reduced Zs for Type C's
How much load is on the 32amcb ?
You may be able to put it on one 20a fuse
And the other 2 x mcbs on the other ?
It all depends on how heavily they are loaded ?
