IP rating of SELV lighting in bathroom zone 2

Farmboy

Regarding figure 8.1 in the OSG (page 94), for the ‘zone 2’ row, the ‘current using equipment’ column appears to make no distinction between ELV/SELV and LV, so:

  • should (12v) SELV downlights (in a ceiling) also be minimum IPX4?
  • what do you think about (12v) MR16 lamps and their connectors being in zone 2 and accessible to a person using the bath (albeit if they stood on the bath edge to reach across to touch them)?

    If your standing on the edge of a bath they won’t be in zone 2

    The scenario is that there is a bathroom mirror next to the bath. The mirror is surrounded by a wooden frame, The downlights are installed in the top of the frame which is approx 2m high from floor level. The fittings are open-backed with one being approx 0.4m from the edge of zone 1, so is within zone 2, with the Tx lying next to them. Being 6' 4" I can easily reach the top of the lamps and their push on connectors from the floor, as can anyone who had a mind to stand In the bath or on the edge of the bath and reach across - perhaps unlikely but possible, and consider protecting people from their own carelessness.
