This reminds me of a "hilarious" conversation I had one time when I was in the casualty ward of the local hospital.
"So there I was at home and I cut through an electrical cable with some scissors."
"And you came to A&E because you got shocked?"
"Well I was shocked, yes. I didn't expect the cable to be live, there was a big bang and all the lights went off"
"OK you've had an electric shock?"
"No I was surprised, I was not electrocuted"
"So why are you here ..?"
(Paranoid partner made me go, though I was certain I was fine. Had some fluid taken from my spine; apparently electric shocks can cause "stuff to break down" and they were gonna use the fluid to confirm whether I'd been hit by electricity or not.)
Electrocution means death by electricity and shock is damage by electricity up to but not including electrocution.
