My boss gets to go before the Plant Manager to justify why we need to spend the money to do a arc flash study . We are a Aerospace manufacturing plant with about 500 employees . We have 480V through out the plant , three services , 4000 amp , two 1600 amp . Just looking for some thoughts on what you would tell a plant manager . My boss understands its in 70E but any thoughts would be appreciated ....
I guess a lot depends on why this came up in the first place.
It needs to be done.
Either now before it is some kind of problem, or after an incident.
Keep in mind that the study will be the cheap part, and only the first step. Training, signing, and gear are not cheap. And the increased labor costs to do what are now mundane tasks but will be transformed into major headaches are what will cost the real money. People do not like to talk about it but I have heard that in some plants it will double their cost for electrical labor.
An associated issue is down time. A lot of places are running very lean with as little down time as possible. Following the rules, especially those about not working on energized equipment, is certainly going to result in a lot more down time. Lots more.
