[TCML] Main ground vs RF ground

In the majority of instances, the RF ( or secondary base wire) should
have its own "RF" ground rod. Hooking the secondary base to the "house"
ground can lead to problems with items that contain circuitry boards...
and thats about everything as far as appliances go... computers, ovens,
stoves, refridgerators, garage door openers, touch lamps ( the kind you
touch to turn on) will eventually fall prey to the wrong grounding
techniques. But since you are asking about NST's and the Terry filter,
if you are running a single low powered NST with a Terry Filter, you may
not have too many issues to be concerned about, but if you are running
multiple NST's, I would consider a separate RF ground to be safe...
Replacing the stoves controller board isnt cheap... ask me how I know
about that one ;)
There are some instances in which the NST is wired with the case ground
on the center tap of the unit... IIRC grounding the case and secondary
not too sure about this situation.... see if someone else has that answer.
