Jim,

I use two separate grounds for my system.  The main RF ground is used only for
the secondary ground.  I have a separate ground system that is connected to the
pole pig case, center terminal of the safety gap, and the 60 hz ground for the
control system which includes the switch box cases, variac case, etc.

I did not disconnect any connections to the neutral terminal.  I just input
power into the two outside terminals which would normally be the 240 volt out
taps and connect nothing to the center terminal.
