The PDF that Steve has sourced is the ESC version 2a - and is the same version as on their website. It blabbers on about sockets likely to be powering outdoor equipment. I wish the ESC ( or a another ) would issue a more recent version that addresses the issues TODAY. For Example is the lack of an RCD on the lighting circuit a Code 1 , Code 2 , Code 3 or Code 4. Please help ...
That's why I'm asking the question - It is not my opinion that counts - it is the Regs opinion - I can have a personal opinion but when that opinion has a huge financial impact - it is not appropriate to have a personal opinion - the opinion has to be a universal opinion - hence my addition to this thread.
So your comment about questioning my knowledge is not appropriate - I just need a little guidance as to what others consider appropriate Codes for Lighting circuits without RCD protection. Maybe the penny hasn't dropped with me - but it is obviously a Code 4 issue, but was just wondering whether it should be any higher.
Thanks WirePuller - You say that 'plenty of lighting circuits do not require RCD protection' - I think the opposite - I can't think of many older installations that would meet the criteria of not requiring an RCD. Plently unearthed conduiting or cables plastered straight into the walls less than 50mm. Therefore most would require an RCD ie Code 2. Hence my original post ...
The regs are not rectrospective,if an install complied with the regs when it was installed,but does not meet the current requirements of bs 7671,in most cases the code would be 4.
A lighting circuit in a commercial property surface wired and on a TN system would not require RCD protection.
A lighting circuit in a domestic property surface wired would not require RCD protection.If that circuit included a bath/shower room,that would be a code 4.
A lighting circuit with buried cables wired prior to the 17th edition (2008)did not require RCD protection,it was safe then and it's safe now...therefore code 4.
RCD protection cannot be a substitute for lack of adequate earthing....if a lighting system with class 1 fittings does not incorporate an earth that would be a code 2 or even a code 1 if there was evidence of a low IR or failing insulation....Lack of RCD to such a circuit ( even if it is required) is a different issue altogether.
