Hello,

I am about to refurbish a 1960's flat.Â* Walls therefore are plaster on
masonry (brick) and I intend to install 8 "new" double sockets so will
need to recess that number of steel back boxes.Â* Not something I have
done for some years.....when I did I used an angle grinder and it was
horribly messy/dusty.

Forget distributing 240V.

Thread the house with USB power connections.

/me runs, that way... ;-p




FWIW I'm aware of the use of these things in conjunction with an SDS
drill- not tried myself.
