Is one side of your mains grounded? Here in the US, the most common
distribution is a 120-0-120v distribution transformer with the center tap
connected to ground. So, for common 120v wall receptacles, one side (in
addition to the grounding prong) is grounded. I've popped the GFI on my
workbench outlet on several occasions--in every case, it involved a "hot
chassis" piece of equipment. Sparks are pretty, but I'll take the
inconvenience, thank you.
