Hello Davidni,
"I need an extension lead as my ancient one is heating up a lot and I'm worried."
Do you unroll all the cable, if not it will heat up with a good load on.

Its not on a reel so is always used uncoiled...but its just ancient and hasnt been looked after before it was given to me and I havent exactly nurtured it as I didnt buy it (wrong attitude I know but its different when you have to dig deep into your own pockets eh?).
