This was mentioned last year; I see that the FAQ has an excellent article
on the subject, although the link to Hepworth is dead.
I've just disinterred an article from its box, so had a search. There are
[at least] 2 good sources (although they're really the same content), one
of which is a live link to Hepworth:

http://www.hep2o.co.uk/bititesguideearth.htm

and, as a PDF:

The stuff on equipotential bonding in bathrooms has changed with the
17th edition of the wiring regs.

If the supply is fully rcd protected in that location, the requirement
is reduced or eliminated.

(I also noticed that the head of article says "by Paul Cook of the
Institute of Electrical Engineers", but it links to the IEEE - the
american institution. The name of ours has also changed to the IET,
Institute of Engineering Technology)

Agreed, however supplementary bonding rules may still apply. Take a bathroom
with an electrical installation that meets the 16th edition and then you add
an electric shower. The 17th edition will probably require the cable for the
shower to be RCD protected but if you are not touching anything else
electrically in the bathroom then the new shower would need to be
supplementary bonded to the rest of the bathroom electrics (and metal
pipework).

Ta, I replaced the link in the FAQ with that one.

Thanks John. The FAQ really is good and my first place to look when I need
information.
