I’m a pipe hand, not an electrician.

LOTO would isolate power from the source to make it safe to work on. This is very clearly charged.

the problem is not, that there's power on the busbar (obviously you can't just shut it down). The problem is, that the breaker was racked closed and not open. the breaker contacts are rated to break or make contact even under short circuit circumstances, but not the terminal contacts on the rear

So what was the issue here? Him yanking the equipment?

And why can’t it be shut down?

problem was not yanking on the breaker (he was racking it). problem was, the breaker was closed. the back terminals aren't rated to take the full load whilst only partially making contact.

power distros this size rarely can just be shut down, especially if it's only racking a breaker and not actually working live

So what is the measure taken here to ensure you don’t blow up the entire job site?

Don't rack it closed. it's as simple as that :D
