I currently have a wylex box with a main switch and a pair of RCDs, 10 5 ways each, but no non RCD ways.
Im planning get a feed added to my garage and it has been mentioned that I would be better coming out preRCD, even better out of a dedicated switch fuse, but if a 40amp mcb is used in t eh house CU, with 16amp mcb's in the garage CU, there should be suitable discrimination.
Anyway, I need to get a electrician in, but while im at work and thinking about it, how feasable is it to shuffle the lot along an make and non-RCD way?
Currenly my box looks like this (image from google) with two cables coming from each of the main switch load terminals, running round one each into the RCDs, with a neutral bar each.

This is an image of a box with a non-RCD way, which clearly has slightly differenct cable routing and one less N bar.

As I only want one single non-rcd way, could you just link it out of the top of the first RCD
Like this
How allowable is that out of curiosity. I dont really see to much issue with it coming out post RCD as the risk to the house of that RCD tripping is fairly small and the inconvience of going to the house to reset it if ti should trip is also fairly small.
The garage CU will i suppose only have a single RCD so it you would already loose you lights if the power tripped.
