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.

Inverters no longer break the bank!
There are many electric motor applications where an inverter (or variable speed drive/VSD) is better than fixed speed/direct on line, with price as the only drawback. Traditionally inverters have been too expensive for many uses, but as technology advances the price of inverters continues to fall w
