Obviously you'd change the receptacle device. Don't forget to wrap some black tape around the white (previously neutral) wire at both endsLEAFer wrote:Yes, but I wouldn't want to do that with a 120V NEMA 5-15/20 receptacle ... it WILL cause accidents. So, converting to the NEMA 6 series (which is 240volts) will prevent that. But, of course, in addition you would do as you said, "convert" the 20A dedicated (only one outlet) circuit from a single to double-pole breaker (and watch the wiring hot-hot-ground when you replace the plug at the end of the EVSE).LTLFTcomposite wrote:not to mention if you have a dedicated 120v 20A receptacle you could convert it to 240V just by changing to a double pole breaker
Any expert here ... agree this would work ?
(Edit: to keep the EVSE unmodified, could make an adapter (or pigtail) instead (from NEMA 5-15R to NEMA 6-20P.)
The pigtail is a good idea. That way when you call the dealer to have it towed in for repairs you can just stand there with your hands in your pockets and say "I don't know what happened, it just started smoking!"
