So this may seem a bit controversial, but now that Tesla is no longer shipping the 14-50 adapters with the UMC / new vehicles, I would like to throw out there that 14-50 is perhaps no longer the logical receptacle to install for home installations. Here are the benefits of a 6-50 receptacle over a 14-50: Does not require a neutral wire which is an added cost Cable is smaller in diameter and more flexible, so easier to install Receptacle is less expensive Less wires required in the wall box makes for easier installation Here are the downsides of a 6-50 over a 14-50: Future EVSEs might not come with a 6-50 receptacle option (though there are J1772 EVSE's that support 6-50 right now) You can't use the receptacle for visiting RV's (most EV owners won't care about this) Buying the 14-50 adapter from Tesla instead of the 6-50 would allow you to use that 14-50 adapter elsewhere when on the road (and 14-50 is more common these days than 6-50) Here is a back-of-the-napkin example of a basic installation cost comparison: Now this assumes basic 6 gauge copper NM cable and at 100 feet (which perhaps is a little longer than the average install?) The 14-50 comes out to be almost 62% more expensive! Now, if you are paying a professional to install this, the vast majority of the cost is probably their labor and the delta cost for them to do a 14-50 vs. a 6-50 is not much (6-50 is going to be less stiff so perhaps marginally easier to install). Am I missing anything here? What do you think?
