My shed extension lead was stored in a neat, wind-away cassette, holding about 15 feet of cable. My son was doing something with his motor bike involving an electric drill but its lead was a little too short, so he unwound about 2 feet of the lead and went to work on it. The cassette caught fire and burned a hole in the bench.
Has anyone else experienced this? I think there should have been a warning of it, embossed on the casing.
I don't understand how heat was generated in the coil, not having done physics at school. Acting like an induction coil perhaps?
