I need info on Motor Control Center labeling for NFPA 70e regulations for Arc Flash warnings. I can get most of the info I need for Flash protection but cannot seem to find any info for the Shock protection. It asks for Limited Approach Boundary, Restricted Approach Boundary, Prohibited Approach Boundary and VAC Shock Hazard when: fill in the blank. I cannot find this information anywhere. Does anyone know what I am talking about? HELP!
