Being from France i'm having a bit of a brain fart when looking at UK wiring systems. In our systems, neutral and live come out the top of a breaker and go directly to the circuit (we have radials here, no rings, not allowed in our regs) and we also have no neutral bar for individual circuits, only for rcds.
I watched a video of a guy who seems very 'engineer-y' saying that isolating a single breaker doesn't really isolate the current because the shared neutral bar is still live, presumably he means this makes the neutral on that circuit live too. Is this true? I swear i've seen people say just turn off the individual circuit and then you can get working and it's fine.
So i'm very confused now. I'm a newcomer to electrics so please be gentle.
