strung together this:

Errrr... I must be missing something here. What is the point of connecting all
the bits of metal together but not to earth? This doesn't "make everything in
the bathroom at the same voltage". It just makes them all 'floating', just the
same as if you leave them individually 'floating'.

By cross-bonding everything you are holding them all at the *same *
floating potential. If you don't cross-bond them then they are at
*different* floating potentials.

If they are floating there is no source (or sink) of current to do any damage.
