Indeed, but I suspect that what eric was trying to say was that, if something is not compliant with the current version, whether or not it was compliant with the version at the date of installation might affect how it would be 'coded'.
Kind Regards, John
Yes that is the problem, we are told regulations are not retrospective, so if it was allowed when installed, then it should not attract a coding, however there has to be a limit, if we say previous edition is that BS7671:2001 or the 16th Edition. Huge difference between 1991 and 2001 in what was allowed. In 1991 it was not a British Standard that came in 1992.
When BS7671:2001 came out we were told it was in essence the 17th edition but they were not numbering the editions any more, then the 17th came out. I would consider BS7671:2001 is the demarcation line, and if it does not comply with BS7671:2001 if you think it falls into one of the three codes then code it, if however you feel the thing noted could effect future work, then it should be noted but not coded, so no RCD noted but not coded with a TN installation. However reading the best practice guide it seems that is not the case.
I would not code having a plastic consumer unit, or no RCD on the socket supplying the fridge, however for a socket likely to supply an item used outside, then it should attract a code. As should no earth on lights. When the regulations become BS7671:2018 then it would move to what was allowed in 2008.
C3 is improvement recommended, so an electrician can clearly recommend an improvement even if not required by the regulations. "I think you need two lights in this room." is an improvement recommended, as is would be better to change the consumer unit to all RCD protected. So one could not really say an electrician is wrong giving it a code, however the best practice guide seems to contradict itself. "Items worthy of note, which do not warrant a classification code. (These comments would not appear on the EICR)" How can you note it and it not appear on the EICR? However that's what it says.
I still can not see how one can raise a C2 or C3 coding due to something which is simply plugged in. However best practice guide says you can, to me it may be lethal and one may feel you should cut off the plug, however that is not your job, it is beyond your remit. If there is some thing plugged into a socket which is not to BS1363 I would remove it, bag them and hand them to building manager for disposal, even if there design is
fataliy flawed it is not up to me to dispose of them.
