Well Pump Control Relay


What colors do I plug into the L1 and L2? I have Black, Red, White and Ground coming from my panel. From the well pump, they are labelled in the control box Black (B) Yellow (Y) Red (R). That one is easy. Trying to wire my well pump to this Controller.

Check the voltage rating of the pump. IF it requires 230-240 Volts, then

L1 = Black
L2 = Red

You probably do not need to use the white wire with this equipment.

That is what I thought, however, what do I do with the white wire, just put a merrett on it and leave it inside the control box?

Typically a 240 VAC submersible pump with a control box requires 2 hots from the panel through the pressure switch to the control box. So connect the black and red to L1 & L2. Put a wire nut on the neutral (white wire) at the control box and the circuit breaker panel. All 3 wires to the well pump must be connected at the control box.
