Over 20 years ago, I entered this august forum to enquire if I needed GFCI on a hypothetical 240V outlet in my US kitchen to power a 3kW British electric kettle - 2kW is rather tiny gentlemen, please! And basically if I could even, theoretically, have one - the consensus was after much debate - yes.
At that time it was agreed that only 120V circuits required GFCI.
I am now long time back in the land of 240V to ground - in fact my local supply is 250V, but still within spec (<253V) - and I am still alive. I have heard no reports of anyone dying in my town from electrocution, so I assume that this voltage is still quite safe domestically - when safely installed and used.
It certainly reduces the amount of copper required around the house.
A UK portable site transformer 60-0-60V (a safety requirement on all building sites here for mobile electrical machinery) powers all my US shop equipment via NEMA receptacles and is used here mostly daily.
