    [QUOTE=EPAIII;3428746]Jim, That lightning bolt just crossed a mile or more of AIR, which is usually a great insulator.

    Not once it's ionized. Then it's a dead short.

    You know. Camaros will spin, too, if you go into a turn fifty knots too fast and keep your foot in the throttle.

    Most often when fitting a VFD to a machine one eliminates all the original control wiring, with the motor power going *direct* to the VFD
