First I will start off with some pictures of what I am working with. My basic question is what would be my best option and max amperage I can use for my electric car charger? The first photo is the incoming main outside the house right below the PGE smart meter. The second is of the houses main CB panel. The house is older built in 1967 and only 1300sqft, I do not use the electric dryer CB since we have a gas dryer and also a gas furnace. The electric car charger I purchased can be set to handle anywhere from 12-80 amps.
The incoming main box is opposite side of wall where I would want to install the car charger inside the garage.
The main panel inside the house has a 50amp CB for the electric stove, 30amp CB for the AC, 40amp CB for the dryer, plus the 5 other 15amp breakers for outlets/lights.
Is it possible to add a separate second 100amp breaker box directly from the incoming MAIN to only feed the electric car charger? Or would there be a better way to do this? Want to know my options before I hire an electrician to install this.
