The existing service switchgear was replaced at the electric utility’s St. Louis headquarters. The new switchgear has two mains (preferred and alternate) with automatic and manual throw-over, metering, 5kV feeder breakers, 5kV feeder work, and 120 volt DC control power.  Numerous existing substations were served by this switchgear and had to be reconnected. A short circuit, coordination, arc flash study and a detailed phasing schedule was included.
