I was drilling near a panel 30+ circuits worth of romex stapled to the surrounding joists, so I was very careful to check the backside and move the romex out of the way, forgot to do so on the 5th joist and hit two live peices of romex

Doing electrical demo I cut both phases of a live 208 volt 40 amp circuit while standing on a 10 foot stepladder, it turns out that there were three panel feeding the place and I had thought it was safe because I had turned the main in what I thought was the only one off

putting up some light fixtures, screwed the threaded post that holds the shade up to far into the bar and only got a few threads on the nut, it stays in place anyway, few weeks later family is eating dinner and CRASH! shade comes down and dents dinning room table, customers were nice enough to pay for damages as long as we come out and re-hang the (amazingly unbroken) light shade
