I've only ever been on the maintenance/commissioning side of Arc Flash training and I'm being asked to make sure a panel meets Category 0. I know that's the lowest category, so it should be easy to meet, but I'm having trouble gleaning the actual requirements out of NFPA 70E.
The biggest question is if we can have the mains come into the cabinet to a disconnect like normal or if we need a sequester box for the disconnect. It is sounding like we might, but that seems odd that the lowest level arc flash category would require something so abnormal.
