I am utterly terrified of electrocution.
When we were selling our last house, the inspection report showed that there was a missing nut somewhere inside the main box. (The inspector when
we bought the house apparently didn't notice the lack.) A bit of calling around determined that to correctly replace this nut, we'd have to shut down power to the whole house from the street, which required a goddamn
city permit, not to mention several hundred dollars in electrician's fees.
So instead, we bought a $30 pair of electrician's rubber gloves on the internet, a stupid 10-cent nut from Lowe's, shut down the breakers, and Mr. Clod put it on himself. Everything worked out fine, but I kid you not, I was standing there with a wooden chair ready to beat him back from it if it started electrocuting him.
Then the lady buying the house wanted to see an electrician's receipt.
We told her it had been packed, and sent a digital photo of the new nut in its place instead.
