Anyone have any thoughts about an extension cord for the NEMA 14-50 outlet? If I had a ten foot extension cord it would optimize where I could park in my garage. It looks like it's just a straight RV type outlet and an extension cord would work fine.
Warnings for high powered devices always warn to NOT use an extension cord. This is because it is all too easy to have undersized wire melt and/or cause a fire, burning down your car and garage. A properly made extension using SO or SJ cord with #8 AWG (or thicker #6 AWG) wire can do this safely, as long as the connection stays in a dry location.
You would be far better off hiring a professional electrician to just move the outlet closer to your car. You don't want to take chances with that kind of voltage.
This topic has been discussed extensively in the past. See

@nickjhowe and @jat.jaet seem to be not only experts but also handy.
I bought a 50 Amp extension cord for emergency only, but awaite delivery.
Really wish I can buy 10-30 and 15-30 adapters.
They also do not have to move the outlet. They can add another outlet off the same one that is there now, only use one at a time.
@Sudre_ - generally that will not pass code, as higher current devices must be the only thing on the breaker, and two outlets don't qualify even if you don't intend to ever use them at the same time.
As long as you get an RV extension cord that is rated for 50A (or 40A continuous), you should be fine.
That's not true jat. You can have 14-50's as a general purpose outlets in a shop or a garage (pretty much anywhere) for portable welders, potable air compressors and the like.
I haven't looked to closely at the new electric car part of the code tho.
You can't install a second 14-50 on the same circuit on less the breaker and the wiring is rated to support both in this case 100A. However, you can use the first outlet as a junction box to extend the wiring to a new termination. Just Install a blank cover over the junction box(existing outlet). It is never a good idea to use an extension cord as permanent installation even when it is rated for the job.
@Sudre_ - you are correct: section 210.3 of the NEC says you can have multiple outlets on a circuit with up to a 50A breaker (local codes may vary) - I had remembered the limit being lower.
@rsimsic - This should work for you: http://www.amazon.com/Camco-55194-Power-Grip-Extension/dp/B002XL2IG8/ref...

Closing in quickly now on my first 1,000 miles behind the wheel, my Tesla Grin has not faded a bit. As I've said elsewhere, I couldn't be more impressed...
