Plug Socket recess too deep

[NorthernButters]

All,

I tried to chisel out a recess in the brick work in my house so that I could put a metal case in order to put in a plug socket with a flush plate. I ended up digging it too deep so the metal casing is too shallow.

What can I do to resolve it? Any suggestions would be great.

The only thing that I can think of is getting a 35mm metal flush casing, instead of the 25 mm one i've got. Only problem there is that it's just been plastered, so don't want to muck up the plaster as I suspect I'll have to dig out more brick work.

Thanks

Leave it alone and get longer faceplate screws.

clean and moisten the hole, mix up some sand and cement, pack the socket box in with that. It does no harm to have a deep box as long as it is surrounded with flameproof material. You can get some 50mm faceplate screws easily enough.

btw a 25mm box is inconveniently small and tight to wire in. 35mm is much better.

After moistening etc, my thought was would some Bonding not suffice?
BG datasheet says Bonding does have good fire resistance.
Not sure if it's as much as sand/cement, but perhaps easier to work with setting the box.
Always interested in exploring possibilities

I would agree with the 35mm deeper boxes easier also.

sand and cement sets slower so is easier to work with and pack round the socket. It is also far stronger and better at holding the socket in place, and cracks less.

Gypsum plaster has a particular advantage in fire-proofing as it absorbs heat and releases the water that made it set. it is used in some fire-safes , and around steelwork, for that reason. As it releases the water it turns to dry powder again.
