You have to do a service upgrade. The main breaker in the ats is going to be a 200. Unless you can change the breaker to a 100 you will have to upgrade the service.ctsparky said:Customer bought a package deal with a 200 amp service rated ATS with 17kw standby generator.
Can the existing service from "service point to meter to 100amp service conductors be installed into the ATS? Can a 1/0 SER be used from ATS to the 100amp electrical panel? (separating the grounds and neutrals), and leaving the current electrodes (ground rods and water meter bond).
Or is there a code reference that states that everything needs to be upgraded...
any code references would be great.
