A family member of a friend of mine has had a lot of work done to their house, and it seems the builder has done some alterations to the kitchen and bathroom. I'm pretty sure he isn't Part P compliant but we haven't established those details yet.
The first query they have asked me to look at is the installation of some 230v downlights above a shower which are not IPX4 rated.
The ceiling is above 2.25m so not in any zone.
Can anybody help in finding any regs that say this is not aloud.
I have read through Chapter 701 and there isn't anything there specifying certain luminaires above a shower.
The guide to the building regulations says on page 65 that luminaires above a shower must be IPX4 rated, but that's all I can find at the moment.
Many Thanks
Dave

Should be suitable for the environment whether in a zone or not! (doesn't sound like they are)

Yes I agree, but they're asking if there is any associated regs that they can use to confront the builder with.
If they are not suitable for the environment then surely there should be some regs about it?

If the shower is not of the fixed head type, at a tenuous stretch you could say that the equipment exposed to water jets should meet IPX5, though generally speaking this could also be applied to any type of equipment out of zones in a typical bathroom, such as a ceiling pull switch.

132.5.1 "The design of the electrical installation shall take into account the environmental conditions to which it will be subjected".

If it's outside zones, you're into the realm of opinion about whether a certain piece of equipment is suitable or not (chapter 32 of the regs is still rather brief), unless you're lucky and can find something in the manufacturer's instructions....
