Genious Don! Thank you. That is an awesome idea. I guess I could ground the box to a copper grounding rod 6 feet into the ground outside - which I am going to install for the solar panels and inverter system anyway. That way the 4th wire of the EVSE receptacle (female) in the box would be grounded to the box and to the rod in the ground....so then I am protected by the fuses and the grounding. I am not sure abou that but grounding sounds like a good idea to me just in case anything gets in contact with any of the 240v at some point. And in the solar/turbine system that I'm hooking up too....which is 24v...and it says to ground it on the positive side of that system. And to run grounds to the housing of each panel. So all of that would have to be connected to the ground rod eventually. I think I'll run all of this by the electrician before I turn it on and maybe just continue with the 120v for now. If I'm going to install a box for EV charging, maybe I just want that to be done by an electrician - with your suggestion in mind. Would be a good first step working with the electrician.
First step would be to upgrade my dryer plug to 4 prong receptacle (with new wire from main utility panel) and also install a separate EV breaker box with the fuses and ground the whole thing. I could also get my 100 amp main box replaced with a 200 amp box because I need to do that anyway and that would take care of all of my main big wires and the major upgrades. The I could do the other stuff later with the solar/turbine/battery bank and also the conversion from gas hot water to instant electric water.
I think you really helped me get to my next steps. Thank you!!! If anyone has any other ideas based upon hearing the other factors I just mentioned let me know!
Thanks for your help!
