Pfft. I didn't get where I am today by making sure everything was unplugged before rummaging around with wires, or not bypassing safety cutout circuits with tin foil and melting fan heaters into a puddle of goo or not cleaning urns that are still plugged in in a bath of water or removing a thermal cut out valve from under 20 litres of 80c worr balanced on a chair with one hand...Call me triggered, but having the better half of the year no use of your attic because of some stupid heating thing touching some stupid plastic thing is ANOTHER thing that matters.
Keep it safe folks! Penny wise, pound foolish etc.
No sir.
Praise be to modern circuit breakers
