Don't see why - it really isn't difficult to look at where the plane bounding Z2 is, and to see which side of it the transformer is.
You call it academic.
I call it simple physical layout and what the regulations actually say.

As I thought transformer would have to be outwith zone 2 initially.
Not confused, I'm a sparky with not much domestic experience. Thanks for everyone's help
Fair enough. However, even if you're not confused, I am a bit - at least, about the relevance of what has been said.
As I suggested, it does seem (to me) a bit academic to say (technically correctly, I suppose) that even if the faceplate of an accessory is in a zone, the bits on the back of the face plate aren't - since it is the faceplate that defines whether or not 'the accessory' is in a zone (and hence whether it is 'permitted' to be wherever it is). After all, any accessory will have some sort of terminals etc. 'at the back', but that doesn't alter the fact that the accessory will be 'within the zone' if its face plate is within the zone (and not 'within the zone' if its face plate isn't), even though its terminals etc. are technially not in any zone
The 'other way around' (if it could ever happen) might have relevance, but I cannot think of any sensible scenario in which a faceplate was not in a zone but it's terminals etc. were within a zone.
Ah well! Regardless of these discussions about technicalities, I think we all understand 'what matters' in practice (i.e. what matters to you)!
Kind Regards, John
The part IS allowed in zone 2 so surely its construction is irrelevant.
Exactly! That's why, in my opinion, the fact that the bits on the back of the accessory are probably technically not in Zone 2 (not in any zone) is totally irrelevant!
Kind Regards, John
Yes, as for discussion, what if you used a pattress for an item which might be as described?
Quite. The fact that the transformer/terminals etc then would be in Zone 2 would not make any difference to anything. Provided only that the accessory was compliant with the relevant Standard, it would still be allowed in Zone 2.
Mind you, although he said that it doesn't, I don't really see why BAS's argument wouldn't mean that an accessory with its faceplate a few millimetres below the wall surface was not in any zone - which would be plain daft.
Kind Regards, John
Yes the shaver socket would but I was thinking about an item described by Bas.
I can't really think of anything which would be allowed in zone 2, although containing parts which would not except for the fact that these parts are not in zone 2 because of their depth.
It would have to be described as such which seems pointless.

Having said that, I suppose ALL items, which are allowed in zones 1 or 2, DO contain parts which obviously would not be on their own - i.e. live metal bits etc.
The shaver socket does have exposed live parts at the back - well, terminals, at least - which would not be allowed.
It is presumably allowed because (as well as the socket being separated) these are not accessible when fitted and not because they are not technically in the zone.
Electric showers contain all sorts of hazardous bits which are, in fact, in zone 1.

As you say, obviously. Exposed 'live metal bits' are not allowed anywhere, whether in a bathroom zone or not.
See above.
Quite. It is the accessory as a whole which is (or is not) allowed, regardless of whether it is flush-mounted, 'recessed' or pattress-mounted.
