I'll preface this by saying akirk above probably knows a little more than me about electrical installations, so bear with me!
I kinda understand the logic of ring main circuits. But I've just read, (before reading MikeJhn above about socket limits in France, so maybe irrelevant question now), that radials can have unlimited sockets on 2.5mm cable (under 50sqm area, I think it said). It did explain this would be for normal home type usage, not large draw such as a line of tumble driers.
So my dummy question - how come it's ok to have the single radial cable just daisy chaining loads of sockets? I must be missing something, as that feels to my tiny brain, a bit like a spur?
If it's just too complicated to explain, just tell me to wind my neck in and concentrate on something I understand
