Re: [CAD_CAM_EDM_DRO] Re: 3 Phase rotary converters

This is the one I used on my 10 HP converter. Works Great. I used it with
a Grainger 4DD05 Contactor with the current paralleling thru both sets of
contacts. the 6X550 controls the 4DD05. BTW, got a bad 6X550 on the
second one of these I built (for a friend).

And for your next question I used 150mfd RUN cap from L1 to the manufactured
leg and 100mfd RUN cap from L2 to the manfactured leg.
