Plant layout and equipment location drawings which identify the physical plant locations of hot standby (shutdown) and cold shutdown equipment.
3.
Clearly marked-up electrical raceway drawings which identify the cable routing of power and control circuits for those plant systems necessary to achieve and maintain hot standby (shutdown). Drawings should also identify exactly where cable v,,)ing has been installed and the extent to which cable wrapping has been installed.
