The science of electric shocks.

I was talking to an electrician today, who told me a hair-raising tale about a badly wired building and receiving an electric shock. He said he was blown off his ladder half way across the room by the shock. He estimated he ended up 10 feet away.

So, how did that happen? What was the actual force that propelled him?

Am I right to think of those frog legs attached to a wire, twitching when a current was applied? In other words, rather than be "blown" across the room, was he actually induced to involuntarily jump across the room?

As for details, we're talking domestic 240 volts AC. I assume from the description that the breakers/ trips were either primitive, or non-existent (fuses, maybe?). He was a little unlucky, in that he had turned off the house mains, but the circuit that was left live was a spur from the back of a neighbour's socket on the party wall.......highly illegal.

Oh, and he's fine.
