ECN Forum Forums General Topics of the Trade General Discussion Area Run Cap subsitution question. Two vs. one

Larry,
I would go with 440VAC capacitors, if you can get them.
Yes it is 240VAC, but the peak voltage will be something like 385VAC, you need to think about that with capacitors.
Also, I don't understand why you have two capacitors in parallel, instead of just one in each winding.
With a 5.5 kW motor, you only need a capacitor on the start winding (which is switched out with the C-switch) and a permanently connected capacitor in the run winding.
