No. The grid has ears which rest on the finished wall surface and this stops the grid frame from being screwed in too far. The back box is rarely level with the wall finish, particularly after plastering / tiling. Hence why socket screws are available in varying lengths.

Very...
Just bought into MK Grid Plus system to provide required flexibility for light switches.
Shocked to see that the frames have captive screws held in place by a washer.
Need to use longer screws as most of my back boxes are too far back. Ordinarily you junk the screws that come with sockets...

"Armed" as in "armed with knowledge". Knowledge helps inform your requirements. The better your specification, the more focused the quotes are, and easier to compare.
So DIN terminal connectors for each L, N & E of each cable it is then. I've just watched a video on RCBOs and now understand how they work, so thanks pc1966 for pointing that out.
I want to replace my consumer unit and move it down the wall so don't need a chair to get at it.
However the wires leading to the Consumer Unit are not long enough and would need extending
I gather that compliant way to extend is to use a suitably encased DIN rail with DIN terminal connectors...
