Hey all new to tesla coils and building my first coil, but my only question is do i ground the nst to mains ground or disconnect the mains ground from the case and use rf ground. I'd rather be safe than sorry so i must ask. I have spent countless hours researching and searching the forums, but i have read it both ways and i would like to be 100% sure.

Ocean Waves suggested: "bond rf ground and mains ground togather and use them both"

This is probably not a good idea.

Gary Lau has looked at some of the various options for grounding the power input side of a SGTC when using a commercial EMI filter on the incoming AC line in conjunction with a "Terry Filter".
