     Yes I agree with you terry on that GFI circuitry is easily circumvented,
and also that the transformers with GFI intact also work I tesla coil tank
circuit. In fact I was using the francformer 7560 PG-1 in my mini coil which
has Secondary Circuit Ground Fault Protection, Bypass Switch, and Auto
Reset.  Those features did not seem to affect the performance of that coil.
Recently I depotted that tran and upgraded my mini coil to the new three in
TC system I now run and it kicks out 40in sparks. Although I was a little
surprised to see that there were two primary coil windings on the tran, it
goes primary then secondary the another primary and then the last secondary
coil, other than that I looks like a normal NST core made by franceformer. I
also had to rewire the Tran on account of that GFI circuitry.

BTW is there a formula for calculating the breakdown voltage in a multi
segmented copper pipe spark gap?
