On the meter ratings... Usually the "max continuous amperage" of the meter will be displayed with the letters "CL" or current load.. IE.. CL 100 or CL 200 ... the "15A" seen on some meters indicates the load which was placed on the meter at the factory during calibration.. (typically on older meters)

This is info given to me by a San Diego Gas & Electric planner.

BTW.... So Cal Edison seems to have their own little code here... 100A underground services are typically fed via #2 AL XPF cable... 200A by 1/0 AL XPF cable.. & they want a 3 inch conduit for the latter... I guess so they can "blow" the wires in! [Linked Image]
