Heated towel rail in bathroom Zone 2?

[Phil_R]

Can anyone tell me if it's OK to install an IP66 or IP68 heated towel rail (240V not SELV) in bathroom Zone 2?
The towel rail would be connected to a fused outlet located outside Zone 2 on an 30mA RCD protected circuit.

That should be fine. It's the location of the connections that matter, not the posiition of the rail itself.

Many Thanks for your quick reply. I am pretty happy to go ahead especially as I'm looking at an IP66 or greater unit.
Sorry to add a complication but I'd be grateful if you or anyone has a view on walk-in showers.

All of the zones diagrams show showers in cabinets with the zone 2 extending from a glass side panel. Loads of people these days have walk-in showers with access via a long shower tray and one glass side panel.

In such a circumstance does the zone 2 start from the walk-in shower tray edge so long as the glass side panel is protecting the appliance from direct spray and jets?

My feeling is that such a situation is equivalent to the zone starting from the edge of a bath-tub rather than the whole set-up being interpreted as a wet-room.

Apologies for adding such a complication but it must be a frequent situation.

Gets more complicated with wet rooms. Zones 0 and 1 are determined by a 1200mm radius with its centre directly below the water outlet of the shower. If there is a fixed partition as well, then this 1200mm radius ends when it is outside of the partition and at right angles to it. From there you continue on with a radius determined by this formula: (1200 - y - s) mm, where y is the distance from the centre of the 1200mm radius to the inner edge of the partition and s is the thickness of the partition itself. The centre of this radius is the outer corner of the partition.
The regs. make no mention of zone 2 when these formulae are used, so it goes abruptly from a combined zones 0 and 1 to outside the zones.
