Re: Service Lateral GEC
Table 250.66 is based on the size of the "Service-Entrance Conductor". Check the definition of "Service-Entrance Conductor" I have never seen a POCO size "Service-Entrance Conductors". They size "Service Drops" or "Service Laterals", but never "Service-Entrance Conductors" In my area, the most common new residential service installation is an underground service lateral into a combination meter/main disconnect on the outside of the house. In such a case if there are service entrance conductors, they would be the factory installed conductors or buses from the meter section into the disconnect section.
