I have a moderately sized electrical panel and over the course of the last 8 years have done a full house rewire, and installed heat pumps (and when I say 'I did X', I mean I wrote the check to the electrician). At the beginning the panel was relatively empty because the house was completely under-wired. Now, all the breaker slots are completely full, some with double breakers. Additionally, the system is set up with the mains wiring coming in through a 220v breaker instead of through the top bus bars, which seems weird to me.
Within the last year I put in the Sense energy monitor, which involves putting two inductive clamps over the mains feed. I was able to do it, but it was a really tight fit to get it in place. https://sense.com/installation
I'm about to have a solar install done, and they'll have an electrician in anyway doing the hookup. They're willing to upgrade me to a larger box for the cost of 1 days work of an electrician and his apprentice, $1200.
The solar company seems to think they can get the solar installed in my existing box, with no problems. However, I think this might be a good opportunity to get a larger box so I don't have to worry about it in the future.
I have several opinion questions.
Should I enlarge my box? In theory, I don't plan to add any more circuits to the house, but this sounds like a good opportunity to future proof. On the other hand, I don't want to throw $1200 at something if I don't have to.
Should I insist on the mains being moved to what I believe is the more standard top-center point directly on the bus bars?
Does $1200 and 1 day's work for 2 guys sound like a reasonable estimate for replacing the box in the Boston area? I'm not asking if someone could do it for $100 cheaper, but, just a basic call on whether this price seems reasonable?
Decided to pull the trigger and will be getting a contract amendment to the solar job to bundle the box upgrade. Thanks everyone.
