The common is tied into the ground bus at the main breaker panel where his house gets power. It's all grounded and safe. As far as the holes go, i ran out of grommets and decided to use the one i had left for the hole where the power runs into the controller, seeing as that's a potential load bearing point. Being a wall mount unit with no external controls, your hands won't be anywhere near that point. Had a time crunch on it and a firm budget, but i think it turned out nicely.
