Hi Kevin,

Sure, you can use 20 kV for your primary circuit
voltage, providing that the circuit components can
withstand the increased voltage. The reason ma-
ny coiler opt for 14.4 kV or 15 kV, as you mention,
is that these are standard voltage ratings of pole
mount distribution transformers (pole pigs) and
neon sign transformers (NSTs), respectively. This
doesn't require any custom made transformer. 19.8
kV is also a common pole pig rated voltage, too, but
not as common as 14.4 kV. Scot - aka Bunnykiller,
uses over 30 kV in his Tesla primary circuit by over-
driving 2 seriesed 14.4 kV pigs, but he will also tell
you of it's difficulty of primary component insulation
standoff.
