Services then are extended to an existing 2000A Switchboard with feeder duct. B. This project will disconnect and remove the three (3) existing transformers located in the vault, the air interrupter switches also located in the vault as well as the existing feeder duct and 208Y/120vac secondary switchboard in its entirety. A temporary transformer along with primary and secondary services will be provided. C.
