Would like some feedback from anyone who looked into this, preferably in California but input from other states is welcome too.
My service panel is, as far as I know, 200 amp, and it is completely full. As in, literally, no room left to put in new breakers (and even the ones I have seem to add up to more than 200. I don't understand how people even live with 100 amp panels. Just the two A/C's, the oven and the induction cooktop add up to 150. Not that they are ever on at the same time, but still.)
So, my options are to charge at 120V/15A for the time being, to cut into the line for one of the A/C's with a double pole / double throw switch, or to upgrade the panel.
I am fairly familiar with anything that's my side of the main breaker (I did a DIY ground mount solar install a couple of years back, complete with drawing up permits), but I have no idea what's on the other side. The "other" half of the panel seems to belong to the utility company (SDG&E) since they have a "smart" meter and a seal there.
Now, the questions.
* For a service panel upgrade, do I get an independent electrician, or do I just call the utility company? It looks like they need to be deeply involved anyway. Or do I get an electrician and he coordinates with the utility? How long would _that_ take?
* What about the line from the distribution transformer to the service panel? What's the typical rating there, and is there any way to find out? Mine is buried all the way along, ~100 ft, and I really, really don't want to excavate it for an upgrade.
* How much would an electrician typically charge for an upgrade to 400A?
