Oh blimey...
William Martin Esq, I guess.Indeed so - I presume that 'we' have no control over those pages - so to whom do we complain?
IMO the best thing would be to have a Wiki article already prepared, with an overview of why cables have different CCCs, how installation method affects that etc. Eric seems to have a soft copy of the regs - perhaps he could be persuaded to copy some of Appendix 4 - the relevant installation methods, the table for T/E etc.
When it's all done, ask Admin to edit that page to point to the Wiki.
I wonder what other dodgy stuff is lurking in the "How to..." pages.....
