David,

If the Tesla coil is really relatively small (like 12/30 NST powered or
smaller) then you can usually get away with using just the common
house AC ground for the coil. However, with larger and higher pow-
ered systems, seperate RF grounding is crucial to prevent nasty
transient surges from reaking havoc with other electrical appliances
in your house. In my early days of coiling, I burnt out a 
refrigerator compressor, some sequencing relays in my electric central heating
unit, and also burnt out a wall receptacle on the other side of the
house at just about the same time by using only the house AC ground
without a seperate RF ground for a fair sized coil that I had at the time.
I didn't know any batter at the time ;*O
