Metal clad or recessed sockets for garage?

Another option would be a simple piece of 2x3 behind the box, fixed into the concrete. Certainly I wouldn't try fixing the box into 12mm ply: The stuff is far to thin for a screw into the edge, and even if you managed it it'd tear right off if pushed. You'd also have problems getting conduit to the side entries on the box.

You could screw a 2x1" batten to the back of the ply either side of the cutout to give you plenty to fix your flush box to

Theres no reason why you cant use dry lining boxes, or if you want to be really posh, use metal dry lining boxes

Point, but at that stage I'd have just lumped a 2x3 in the back and have been done with it.

Trouble with dry lining boxes would be the rear conduit entry. Putting the conduit that far back would require cutting a lot more insulation out, and all those extra tees seems a bit pointless.

I can't really get my head around the way this house is going to be constructed, so i'm just throwing some ideas about.

I'm beginning to see it, and it's.. madness.

Plasterboard in a garage? Arrrgh.

I reckon dado trunkings going to be easier

Rather than run the cables in conduit on the surface of the wall,

Why not?

I can easily run the cables in conduit in the polystyrene behind the plasterboard. (This is how it will be done in the rest of the house).

So why not do it in exactly the same way in the garage?

Why is your electrician struggling so much with all of this - did you choose one who doesn't know what he's doing?

Anyone got any ideas?

Get an electrician who knows what he's doing before it's too late...

Thanks for all the replies. I am going to go for dry lining boxes.

Which also has the same problem. Metal boxes on a bit of 2x3 beat dry lining boxes any day.
