RE: The oven outlet box behind the oven for connecting the final wiring to the oven itself.
This will be surface mounted on an area of wall where there is no plasterboard.
Is there any problem surface mounting a metal back box here (it will only be visible and accessible when the oven is removed from the oven housing unit)?
Or should I use a plastic "surface mount" box - they are more bulky and I'll have to go out and get one !
Thanks,
Simon.

to matter. I can't immediately think of a reason for it being actually
"wrong" though as long as its properly earthed - it will still offer
adequate IP protection (assuming you are not using one with half the
knockouts missing!).

Even if there are no other knockouts missing I would use a stuffing gland

and not a grommet for the cable entry.
In the real world using a surface mounted metal backbox is no different than
using a metal clad surface mounted socket or switch.

Knockouts are the issue, if they let a small kids finger in they're no

good, and the metal boxes do tend to have holes large enough to do so.
So watch how you get the cable into the box.

can easily isolate the rest of the wiring and still have a plug socket
to use.

So I ended up using the 40mm box with the wide enough snap-outs and dug it into the wall a bit. It would have been just as simple and cheaper to sink the metal box !
Oh well, things go that way sometimes ...

Remove cooker from kitchen, wheel arc welder in to spalce now vacated

Then you have a spare socket for the angle grinder and lots of space
to store duct tape.

circuit, that can remain powered, even when all the other socket
circuits are turned off.
