Autotransformer w/ GFCI to pool pump

[iwire]

Because the supply is 20A 240v single phase, I believe the GFCI rule still applies.

I agree, it is a single phase branch circuit, what happens to it in the pump is not relevant.

The supply is 240v single phase..... there is a DC inverter inside the pump, and then it converts to 3-phase AC to power the VFD.

The pump in question is a Pentair IntellifloXF. http://www.pentairpool.com/products/pumps-inground-intellifloxf-variable-speed-pump-452.htm

Because the supply is 20A 240v single phase, I believe the GFCI rule still applies.

My bad, I think. I kept thinking of the "Pentair" cabinet pictured in your OP and was thinking it was the VFD and the motor was remote from it.

Do you have the make/model of the tranformers you used and any other config detail? I'm in the same boat now
