I'm still new to working with power distribution... I've only been working around that kind of power distribution for a couple of months.
All the times that I have seen tails tied into the wall or a generator, we've hooked them to the distro before energizing them, and I am trying to think about what situations would happen where it's necessary to have power on camlocks before tying them in, but I can't think of them.
Anyhow- is it normal to have "live" cam-lock tails? Or was the genny operator thinking that the breakers to the legs were open or something?
No, absolutely not. This genny op needed to be sent to the seal room, to think about what he'd done... But seriously, it was very poor practice to do what he did. I should have, but wasn't really in a position to, demanded that he de-energize the tails before he left.
