if anyone's interested . a common fault in a lot of houses is if it has a borrowed neutral. and u change the db this vid explains
If I had 2 RCDs I'd put all the lights on one and all the power on the other. You're most likely to trip a power RCD than a lighting one and you don't really want the lights to go out when you have an electrical fault. If a lighting RCD trips you can always plug a light into a power socket.....
that's the correct way to do it .no matter what happens u either have lights or sockets on the upstairs and downstairs sockets of one or the other go offProblem with that system is if it trips you lose every light in the house, best practice is to put upstairs lights on the same RCD as downstairs sockets and downstairs lights with upstairs sockets on the other RCD.
ive seen a 3 phase and neutral printing machine run in 25 meters of 3 core swa cable and the neutral wired in single cable in to a socket near the printer
