Re: Personal heaters
Sometimes it's not pack of understanding, just lack of (applied) thought.
I once wondered why I couldn't get a high current extension lead with a y-tail and two 13a plugs. I felt very stupid when it was pointed out that if you unplugged one plug, it'd be live if the other was still connected. I'm not usually that daft, I just hadn't considered the possibility of someone unplugging either plug without switching both sockets off first.
