because diy dave has got his big shiny drill out on a sunday!

with the power off, and he just happens to be using a metal drill bit rather than a masonry or wood drill bit?
and is going to just keep drilling despite the drill not going in like it should and sounding like it's hit something metal?

Thinking about it I've been guilty of the 'get the SDS out and give it some proper welly' approach when encountering resistance whilst drilling a hole. I wouldn't be surprised if most of us are!
besides, with the inverter off, even transformerless inverter circuits become protected by dint of being electrically separated.
Switch it back on and the insulation resistance test on start up should detect a damaged cable and not start up, so the circuit stays electrically separated until the fault's repaired.
At the end of the day, it's allowed under BS7671, and it's allowed because it's considered to be safe.
