In dealing with different POCOS, how many of them that you work with have a requirement for test bypass facilities on non residental metering or is that a California thing? PG&E requires it with limited exceptions.
It's a shame you guys all have had bad experiences with PG&E. Both So CA Edison and the LA Dept of Water & Power have become so easy to work with that it's a pleasure. They've both put on "a new face" in the last few years. Customer service has improved so immensely that it's like the difference between night and day.
Use the "green book" as Bjarney says, and life will become much easier for you. It won't make them get to their appointments on time, but at least you'll have your ducks in a row when the time comes. (It's pretty frustrating for the PoCo too, when contractors install things that don't meet their specifications. They've got rules they have to follow, too, ya know)
