The Central Facilities Area (CFA) 12.5 kV switchgear located in the Scoville substation at Idaho National Laboratory (INL) was built using old standards and has safety issues due to low-to-ground exposure. The switchgear consists of overhead bus, breakers, switches and instrument transformers that are needed to feed the 12.5 kV distribution system. These components need to be replaced with new equipment that has the capability to easily ground individual phases for maintenance and has adequate clearance around the equipment to safely perform maintenance activities.
