Another theoretical question I'm wondering about.
Say you have a CU with 3 phase incommer.
Off that consumer unit you wish to run:
One 3 phase MCB for a 32A 5 pin plug
Three single phase MCB's for 16A 3 pin plugs Each on a seperate phase.
How does the RCD work in that case?
Does the 3 Phase RCD simply work on the principle of:
L1 + L2 + L3 = N ?
Does it matter if there is a higher load on one phase than another?
Will the RCD trip if L1 is 20A, L2 is 32A and L3 is 20A?
Or will it be fine as long as what is going in is measured going out again over neutral?
How do the ratings work for it, say its rated for 40A, is that 40A per phase maximum?
