[RE-wrenches] Line Side Feed In and Disconnects

Tue Mar 10 20:23:09 PDT 2009

I agree. A true line-side connection is a new service and requires a circuit 
breaker and disconnect and revenue meter. I guess a better description for 
what we've been talking about is a load-side tap that is between the 
existing revenue meter and the distribution service panel main circuit 
breaker. Wayne, which configuration (line or load side tap) are they 
requiring the new disco?
