This is not a question PPE, but about potential failures in LV switchgear. I know we're to wear PPE where shock is a risk- no question there. But it's also standard to wear PPE during events where no live components are exposed, but there exists potential for arc faults or exploding breakers, etc. What exactly happens when a breaker fails that would cause injury to an unprotected person? What does an arc fault in 480V switchboard look like? I've not talked to anyone who's actually seen a breaker explode, but everyone seems to have heard about some accident 2nd-hand or 3rd-hand with little detail, and are afraid to manually throw a high current breaker without protection.
