NFPA 110 Emergency and standby power systems article 7.2.2 mentioned "Level 1 EPSS equipment shall not be installed in the same room with the normal service equipment, where the service equipment is rated over 150volts to ground and equal to or greater than 1000 amperes". That means all emergency equipment such as ATS, emergency panel boards shall not be located in electrical room if the normal service is equal to or greater than 1000A. Do you guys apply this code for your projects? Thanks.
