Having my city inspection done today and I spoke to the Tesla guy labeling everything. He said he has the sticker but it's not a requirement. So of course I said please skip that one. Success! I explained I want to add a Tesla wall connector and he said I own the system and can do whatever I want to it. Pretty much inline with what the Tesla electrician told me during install as well. (Ive basically asked every single person that's come by about adding loads)
