I am working on building a 7.5 hp rotary converter. I plan on using a
start circuit with start cap that drops out after a potential relay.
----------------------------
I used a double pole NO start push button. One pole to close the motor
contactor and the other to close a relay that connected the start caps.
After the convertor starts release the start button and the relay drops out
the start caps. No expensive potential relay needed.

Here is a shot of my 3 hp converter I built over three years ago. I
outgrew it and thus a 7.5 hp unit. Will be up for sale as soon as I
get my 7.5 hp unit together.
