2) I believe the NEC does not require GFCI protection on 240V
circuits. Are economic 240V GFCI receptacles available?

I don't think I've ever seen one. You can get a 240v GFCI circuit breaker
though.

Hmm, a SquareD QO220 breaker costs $15, while a QO220GFI breaker costs
$90. I have two induction motor loads, a jointer and a dust
collector. I wonder if the greater expense of GFCI protection would
be a good reason not to rewire these motors to 220V.

Thanks, Wayne
