I will hire or DIY a permitted wall charger install and want to make sure I'm doing my load calcs right (single family dwelling). I am calculating I can squeeze in a 60a breaker to replace my 30a breaker (unused wall dryer outlet that I will disconnect). Only 100a service but luckily I have gas dryer, gas stove, gas furnace and gas water heater. I attached a photo of my breaker box and my load calc says I am only using 35a therefore can possibly put in a 60a breaker (to replace the current unused 30a one). Even if I hire an electrician I want to make sure I know my options for this permitted install. Can someone double check?
