'josh' the DC part of your post is totally incorrect. Planet Earth works the same way with DC as with AC. In the past, we didn't see much high voltage DC in contact with Earth. But now some electric cars have high voltage batteries and in an accident, the safety worker have to be careful not to electrocuted.\n\nWith electric cars and even electric tools, I'm more concerned about the Lithium batteries going off like a small rocket. The local SnapOn guy was charging a Ryobi battery in his former garage, near his former SnapOn truck filled with former tools, his former pickup truck, his former Camaro and the Alpha Romeo he inherited from his dad. The new garage isn't quite done.
