And something else about running these 240 lines is that you have to match them to the appliance you are using.
You don't run a 50 Amp circuit breaker for a 30 Amp appliance, thinking you will have enough power no matter what, or you might want to upgrade later to a larger unit.
Don't do it. You will burn your house down.
So, while you are having this line run, know this; when technology advances and these things charge faster/need more power, you will have to upgrade your circuit every time you upgrade your charger.
