Bart, my 240 V 4 A Variac measures 3.6 Ohms, so 0.6 Ohms for a
30 A Variac seems a little HIGH. I think that an "ideal" variac
would measure 0 Ohms at d.c.  Ideally only the inductance 'drops'
voltage, it is after all a variable transformer.

Here's the specs:
>GE, Input 120/240V, 50/60Hz, 1PH, Output 0 - 240/280V,
>30 Amps.
>
I'm measuring winding dc resistance and
>the Fluke reading 0.6 ohms at pins 1 and 4 (full
>winding). Do I have a reason for concern?

>Any comments greatly appreciated,
