My builder and I are trying to figure out if an outdoor recessed mains light fitting needs to have an IP rating.  The thing is the standard says recessed fittings with all wiring inside the ceiling is excluded, but if installed less than 3m above zone 1 or zone 2 (e.g. the zones next to and near a bath, shower, spa, pool, water feature, etc.) then it needs to be IPx4.  So what if the recessed fitting is installed in the soffit?  It is inside the ceiling space, but it is outside and it is also essentially a wet area.  We cannot find the answer in AS/NZS 3000:2000 A3 (2003), and the electrician seems to not be bothered to find out or look in the latest standard until I can point hit to a clause.  Google only comes up with results for insulation.

Is there someone that can help?  Thanks.
