Why not install a 14-30 plug, and buy a 14-30 adapter from Tesla? You will be OK with the 14-50, since you know that you have to manually dial back to 24 A on the car's touchscreen. However, if someone else uses your plug, they may not get the message. Or, if something happens to you, and your place is sold as is, the next owner will not know. Also, if you are ever in a hurry and forget to dial back to 24 A, you will wish you had bought the 14-30 adapter! GSP
