I am trying to figure out what options there for permanently extending a NEMA 14-50 outlet. I found this (Heavy-duty NEMA 14-50 extension cord for Tesla, 20 ft.) on the forums, but I don't think that's going to be long enough. Back in 2012, I had a NEMA 14-50 installed in my parent's third car spage in the garage so I could charge when visiting, if necessary. Now my dad has a Model X coming in May. The third car space is kind of tight, and also, to make matters worse, if you park head-in, the outlet is on the passenger side. What I wanted to do is maybe have some kind of long extension cord solution where we run the extension cord up the wall and along the ceiling, and then maybe have it hang down between the first and second parking spaces and from there, we could plug in the Tesla mobile adapter. Maybe if we get fancy, we could have the cord be retractable. What are the options here? Or is the only option to have a professional electrician do it? I am worried that that would cost a lot. I also reserved a Model 3 for my mom, so eventually, we'll probably need to get a HPWC or something, but we got two years to think about that.
