Question about Polaris Pb4 - 60 Booster Pump

1 Answer

I am replacing an old booster pump with a Polaris PB4-60. I have three wires, One Red, One Blue, and One Green. Now I know the Green is Ground, but which poles do the Red and Blue go? Both seem to say "Load" coming out of the timer box.

It is impossible for us to know what voltage you are running as you did not list that information here.
Typically a green-red-blue comination of wiring suggests 240 VAC connections.

Also, every motor you buy is required to have a wiring diagram on the side of the motor. This should tell you where to connect the wires.
IF you are running 240 v as suspected, both the red and blue wires are "hot" wires on the load side of your timing box. Simply look at the side of the motor and follow the diagram on wiring the pump.

Typically most motors in the USA use a L1 and L2 terminal to connect the 2 "hot " wires.
This pump does come factory wired for 240 volts, so it probably is just 1 each of the "hot" lines to L1 and L2.
Before connecting, make sure you confirm your systems voltage with a multimeter.

Below is a link to the installation manual for this pump. But it does not list electrical diagram since its on the side of the motor.

Incoming wire has red,black,white. What goes where

One of those wires should be green (ground wire). The two wires that are not the ground wire go to the two terminal posts, either way, and the ground screws directly to the motor housing above the terminals. Should be a green screw there. Was this electrical used on a 2 speed pump before?
