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
