you go to install an exterior light(ground floor lighting circuit) extra socket in bedroom ( upstairs socket circuit) and convert a ground floor switch to two way switching. so working on 3 circuits all 3 now need RCD protection you have an old 3036 wylex consumer unit and the owner is not prepared to pay for a new C/U so you end up with a load of separate RCD units next to the consumer unit and it looks lovely
Just wack in a stand alone 30mA main switch before the old DB just like the cheapskates did on old TT instals and all will be well. Bar any existing faults! :^O
17th edition is retrospective for RCD, you only need to note it on the minor works. Sorry but that's totally wrong.
the way i see it (and napit) is that if you add to cableing on a light circuit i.e. switch drop in a wall then IT HAS to be RCD protected. If you add to cabling and it is in a ceiling void or on the surface it does not need RCD protection. Its rubbish about retrospective. You change it then it has to be 17th

And if you were had up in court over doing it any other way then it won't be no good telling the judge otherwise. It's written down in clear text right in the front of the 17th regs.
Taking each part one at a time. you go to install an exterior light(ground floor lighting circuit) RCD required if any part of cable run with wall extra socket in bedroom ( upstairs socket circuit) Fit a socket and it must be RCD protected convert a ground floor switch to two way switching. Unless on surface RCD required.

Can't believe the amount of moaning thats taken place over the 17th edition. The same people were moaning about not having enough work and now the 17th has arrived we should all be thankful. I for one simple loving it. Cant wait for the 18th.
forget the rcds then ,do it the 16th way and note it [/i]as a departure. So is that. why? If the customer insists that they don't want all the extra expense of conforming to the 17th and as for it to be done to the 16th, then you would have to note it as a departure. noticed an article in a nice newsletter from only a year ago ,explaining the correct use of rcd's DO NOT USE RCDs ON THE LIGHTING CIRCUITS it said
Why mess about with the 16th? Go with the 13th and you can forget about rcds, testing except for insulation etc. Just note the departures... If you think that's daft, so is going with the 16th.
