No, Chevy Volt. The reason I thought I would need 3 conductors is because whenever I've looked at recent 240v appliances (Dryer, oven) they've wanted to use a 4 prong outlet. I figured there was some safety reason that 4 prong should be used instead and even though this charger doesn't use it, if the next one does I wanted to be prepared for that situation. If not, I'll stick with the 8/2.
240V = no neutral. The dryer usually has a 120V motor (thus the neutral). The range has the light and possible the controls that run on 120V. The charging stations have no 120V parts. Their job is to charge the battery as quickly as possible. They are always going to be 208-240V. -- If someone refers to herself / himself as a "guru", they probably aren't.
