How many of you in the field have ever had serious arc flash burn?
IMO this is one big reason people will work hot. They havent been burned.
99% of the time you should be able to de energize what you are working on. Period
Yes people may be inconveinienced but Big deal. I would rather someone be inconvenienced than me or my people be put in unecessary danger.
This has been a hot topic for us as of recent for I was burned with arc flash last November, my brother was last Friday, and a maintenance man at one of my customers building was almost cut in half by a breaker that let go.
If you tell your boss you wont work on that particuliar item hot, let him fire you. He would be in a heap of trouble and he knows it!
A simple thing as resetting a tripped breaker can kill you. May take one in a thousand for it to happen, but it could.
