So I must be unusual - every time I have had to do anything new on electrics
I have always got hold of the latest edition of the IEE regs (or the
electricians commentary) before doing anything. Particularly important
where earthing is involved since there is a lot that isn't intuitive.

Of course it won't be an issue in future since all the jobs I still have to
do will have to have been completed by last Christmas! Seriously - in most
cases how can anyone prove otherwise? Although it was pointed out to me
that a really serious inspector could track the serial number of something
like a consumer unit if he really was out to get you!
