Not good enough. It might be IP44 (when used as intended) yet permit condensation to form inside, or might otherwise be unsuitable for continued use in a steamy atmosphere. IP44 means only that it is protected against splashes of water during a 10 minute test, and that it is protected against the ingress of solid objects with a diameter greater than 1mm.Does the manufacturer state it is suitable for use in Zone 2? There's more to it than just the IP rating.In my situation the control is IP44 so ok in Zone 2.
I do get that but as there's nothing really designed to be a switch suitable for Zones I'm just relying on the IP rating which is required for those Zones.
The same applies to 240v down-lighters though surely? Most of them are only IP44.
