I would pay the $300 on this one. I’ve been looking into messing with 220V outlets for a bitcoin mining project, and as I understand those outlets, you’re supposed to have two 120V hot lines, one neutral line, and (ideally but not necessarily if the house is older) a green ground line. If this installation is missing the neutral line, or if the house ground has been substituted for neutral, something’s amiss.
