Electrical panel question

@ESP47 You're going to have to get PG&E involved if you install any type of new meter base. The best thing to do would be to install it around the corner from the garage door and then let them run a new UG service to it. If you are installing a new 200-amp panel also, you could sub feed the old panel that is above your meter base from the new panel. The power company cannot run their service thru your breaker panel unless there is a raceway that is not accessible from the inside of the breaker box. If you install new stuff, you will only be without power for a few hours during the swap over, because the power company and your electrician will have to be there at the same time.
