Mike,
Factory wiring had three start caps and two run caps. Initially I just ordered five replacement caps same value but higher voltage. Then I could not fit everything in the motor junction box. The voltage rating on the caps are for 50/60 Hz. So now I have ordered two start caps at the higher voltage at 150% of the original value. I figured being in the circuit for only a short time during start up, if there was a heat issue I should still be OK.
