Just wondering how interpretive you can be of the new zoning regs for
bathrooms :-}

The light in ours would notionally fall under zone 2, being about 50cm
outside zone 1, however zone 2 only appears to apply up to 2.25m high.

Our ceiling is 2.30m high.

Looking at the pocket guide, i'm not sure if it becomes a zone 3 which
covers an additional 0.75m height, following the same 0.6m "radius"
from the bath as shown on the diagram, or if the zone 3 markings only
apply to adjacent walls as shown on the diagram...

Either way, it looks like a standard 240V lamp would be ok unless you
start talking about the size of lamp fittings ! (which is likely to be
a slim profile enclosed fitting by the time the wife finishes anyway)

Has anyone fitted a whirlpool bath recently ? the regs say under the
bath is zone 1 if accessible without tools, but not what it's classed
as if you _do_ need tools :-}

....also, are they typically LV or 240V these days ? (just trying to
imagine the size of conductors required if it incorporated a heating
element !)

Last but not least, what classes as Class I or II equipment these days
for the purposes of cross-bonding ? - the wording of the regs seems to
suggest either:

a) local cross bonding should go to all terminals of protective
conductors within zones 1, 2 and 3

b) i'm misinterpreting it and you need to take the cross bonding all
the way back to the consumer unit
