i got a shock off a metal shaver socket, i had enough fault current through me to trip the rcd. i travelled quite some distance before i realized what had happened, only just managed to stay on my feet, glad no one was in the way. Ive had loads of shocks but this really hurt couldnt stop shaking for a while. Scary when in a house on your own. I do alot less Zs by measurement now, its calculated.
When we work with other sparks on commercial jobs we are the only ones locking off and using the tester correctly.
I mentioned what happened in the wholesalers and someone said they had a shock off the same shaver socket, strange stuff!
