Yes, it is about 25 - 30 feet from the coil.

I can put the RQ/TCBOR gap at the coil along with the caps, but the
rotary is synchronous so it will have to stay at the control cabinet.

Two H&R's dunked in oil in a plastic toolbox. I plan on having them
next to the cabinet and keeping the leads short  from the variac to
the transformers and the hi-voltage leads will also be short going
back in to the safety-gap, bypass caps, and resistor assembly.

I'm not too sure about using these resistors either. But they're easy
to remove from the circuit.

I'm using two runs of 12-2 house wiring with all three wires connected
at both ends. They are each in  pvc pipe and both pvc pipes are inside
a 3" pvc pipe. This runs down the side of the wall on the floor.
