Re: [TCML] NST primaries
I don't see any harm in trying it. You might also think about connecting the
center point of the two primaries to the 'common' of the 240 volt supply.
This will help keep the coils in balance, which is the purpose of having two
coils in the first place.
This was to insure that there was equal currents in both parts of a
'midpoint ground' wiring scheme. That's where a series of neon tubes (like in a neon
border on a building) are fed at the middle of the string, and the far ends
are returned to the grounded case of the transformer. This keeps the high
voltage wiring to a minimum and the long return wires at close to ground
potential. (Note: Newer transformers with GFCI have isolated midpoint connections
that are not grounded to the case)
This may not apply so much in TC use, but connecting the center point of the
primaries to the common wire (in a 3 wire 240 volt circuit) will insure that
each coil gets exactly 120 volts, even if there is some difference in the
