Dear All,
I would like to ask one important issue related to Arc flash boundary markings in the industries like we have to mark the boundary for wall mounted DB's or not (which can be in Office area). If yes, then what would be the distance in mm or feet. Please advice.
Thanks,
Your arc flash boundary is a calculated value for each piece of equipment based on your arc flash study.
If you don't have a study, you would use the distances listed in NFPA 70E Table 130.7(C)(15)(A)(b).
