Single Phase Capacitance???

[jfmuggs1st]

3 HP, 240 volt, single phase, Cap. start/cap run, FLA 16.8, NEMA design B, 2 pole, 3450 RPM. Start Cap is leaking needs replacing but all capicitance markings are worn off the capacitor shell.

 

Is there a way to calculate the required capacitance???;p;

 

Thanks

Hello jfmuggs

 

Are you using 2 or 1 capacitor?

 

in any case this link is helpful..
