I was watching the video of the electrical charging station installation for the Nissan Leaf when I spied something that seems amiss. Maybe I'm wrong. Happens about 1:20 into the video.
Individual conductors not in conduit?
Do they need a neutral for the charging station?
Nope, It's a straight 240 + ground.
40 Amp too.
sheathing is missing.
It would appear that the wires are pulled in conduit that is not visible behind the box.
