Hey all,

New guy here. I take delivery of my Model 3 in about a week.

I live in an attached townhome. I have my own, private attached two car garage. I was gearing up to have a NEMA 14-50 outlet installed but unfortunately I discovered the main breaker feeding my unit is only 70A. Other than a central HVAC system (240V/30A for the compressor), all the appliances are gas and the remaining breakers are the usual assortment of 15A and 20A circuits for lights/plugs, garbage disposal, dishwasher, forced air unit, etc. What is the largest circuit that can be added to my unit's panel given the 70A maximum? 240V/30A? 240V/20A? Nothing at all? Am I screwed?

The main breaker is located on a shared panel on the exterior of the building. My own unit has its own sub-panel located in the garage just a few feed away from where I was hoping to have the 240V outlet installed. I'm assuming at this point it would take an act of God to upgrade the main breaker and/or panel plus rewire the unit to bring larger wire into my garage (HOA approvals, building codes, whatever...).

I'm in the process of getting quotes from electricians but trying to get an idea first...

Thanks!
