Per NFPA 110, 7.2.2.2 allows EPSS equipment to be installed in EPS enclosure.
7.2.3 states the EPSS equipment shall not be installed in same room with normal service equipment (where service equipment is > or = 150V and > or =1000.)
Does 7.2.3 apply to outdoor installations? Should a separation be considered via a wall between a pad mount utility transformer and normal side switchboard, and the EPSS (generator and ATS's)? The enhanced content explains that high arc fault energy in the service can cause interruption of EPSS which is the reason for separation. Not sure if that simply translates into more distance between EPSS & normal service or if an actual separation / wall needs to be constructed.
