We have an exhisting generator for a warehouse installed around 1990 which has one transfer switch operating entire building, conveyors, outlets, lighting, etc. {there are no battery back up lighting}. Last year under the 2008 nec a new panel was added from main service switchgear for a data center. Now under the 2011 nec. Another Panel is to be added from main switch gear for Machines, Lighting, Office, etc. My question is since Egress lighting with no battery back up is used at what point should have battery back up been added or seperating with different tranfer switches should take place. According to NEC, OSHA, and NFPA
