Dumb Newbie, or Dead 210 EXT?

[Kempy]

Thanks! This unit is single-phase only, so you can't wire it wrong unless the green wire isn't ground. But for everyone's peace of mind, here's a photo:

G=green
X=black
Y=white
Plug is an L6-30P (240v 30A, locking)

I use the same plugs and receptacle did you check the voltage.
