Capacitor Sizes

What size capacitors does my pump need?

Do I need to install capacitors in the panel?

You're in the right place to find out. Capacitor sizes are one of the hardest pieces of information to find out from pump manufacturers! So we've put it into a table to help.

You should check with the manufacture before installing capacitors for pumps, but hopefully this can act as a helpful guide.
