 Roy -- I calculated that without a step-start R, the inrush-I would be a bit over 1000A -- which is probably enough current to weld the contacts in the power contactor. cheerz.

Congrats, Roy. The closest value in my junk box was 5.6½s. ```2nd question: What would the approximate inrush-I be without a step-start relay and resistor?``` cheerz ```_______________________________________________ Amps mailing list Amps@contesting.com http://lists.contesting.com/mailman/listinfo/amps``` Richard L.
