The boxes Blue Fox refers to were in Professional Electrician, they were called "Yoozy boxes" if memory serves, invented by a sparks called Hughes who'd had the problems we've all had with plasterers.
I've had problems with plasterers & dry liners, one particular bunch of c***s I had the misfortune to share a site with carried side-cutters to cut cables & weren't above removing capping or oval tubing to make boarding easier, on one job they even pulled out a door entry cable rather than make a hole in their board. They'd do this then charge to come back & make good where we had to make holes to get our cables back...
I did once meet a plasterer with an IQ higher than a yukka plant, he retrained as an electrician!
