Bob,

Ark-mo has been gone a long time. They are now called Entergy. They are doing one for me that is 40 HP. That is as big as they will go with grounded phase system.

 Co-op (REA) is doing 60 HP with grounded phase (2 transformers)

This 2 transformer 3 phase is some what new around here, at least on the farm.

Will post pics when I figure out how.

Thanks,

John
