For those also interested in VanDeGraaffs a question
This is a video of a VDG I just finished building, You will notice some strikes to the dimmer switch, would it be wise to use a 2 wire + ground for the AC hookup I have instead of the 2 wire only?

If the sparks below the lower terminal are real, because they may be something created by the camera, it's because the lower shield is not grounded, and the electricity is seeking ground through the power supply. It's enough to connect the shield to the power line ground. The average current is small, as this is a VDG and not a Tesla coil, and shall not create interference problems.
