Best practice for stud walls and electric sockets

[JP_]

Building a stud wall for bedroom/corridor that will have 2 double sockets in it.

What is best way to support them? Horizontal advice, one vertical? 2 vertical? 2 horizonal to and bottom?

I guess 2 vertical would make running cables in easier.

And should they be level with the stud wall, or stick out 1/2cm or so into plasterboard? Or be flush with plasterboard, so stick out about 1 cm?

Not sure what you mean here?

If using metal boxes, they are usually level with the finished surface, but a little below would be no crime. They are fixed through the side into a stud or noggin.

You can also fit a drylining box. If you leave the cables tucked inside the drywall, after it is lined (having measured where they are), you can cut a hole and fit the box.
Don't forget to leave a small gap if the socket is next to a stud so there is space for the lug.

Depth so that the edge of the box is at the edge of the finished wall surface, so 15mm which is 12.5mm plasterboard and 3mm plaster skim.

Not sure what you are asking.
Are these metal boxes? If metal than a horizontal noggin behind. Set the box about 4mm proud of the plasterboard, then the plaster with finish flush to the box.

Easier is just cut a suitable hole in the plasterboard and fit a “drywall” box.

Yeah, metal. Need to put existing sockets in before plastering or boarding, so dry wall boxes not really an option.

Why do you "need" to?
change to drywall backboxes, it will make the job easier.

Because I'd need to remove sockets, then board the walls before connecting back, and can't do that as electric will be of for to long.

Have fitted metal boxes today, all measured up perfectly with a 75mm stud on its side for the box to screw into. With board it is almost level. Plaster finish should make it perfect.

Seemed to work. Now need some boards.
