Submersible Pump Control Box Wiring

In this article we ll take a look at the 3 wire 240v single phase submersible pump system for drinking water applications typically set between 50 feet and 300 feet below grade.

Submersible pump control box wiring.

A submersible pump can be either two or three wire regardless of the voltage coming from the panel so start at your pump and follow the conduit back. Here is the complete guide step by step. The wiring connection of submersible pump control box is very simple. If it runs straight to the pressure switch it is a two wire.

When the water tank s pressure switch detects low water pressure its switch closes which turns on the electricity to the control box.

If the conduit runs into a control box before continuing to the water pressure switch chances are you have a three wire pump. Deep submersible well pumps will be either 2 wire or 3 wire well pumps and 3 wire well pumps will need a separately installed control box.

Submersible well pump wiring diagram awesome well pump control box architectural electrical wiring layouts reveal the approximate areas as well as affiliations of receptacles lighting and irreversible electric services in a structure. It shows the elements of the circuit as streamlined forms and the power and signal connections in between the devices. Technicians should test a well pump s control box before pulling a nonworking pump from the well. Once the water pressure reaches the switch s high pressure limit the switch opens turning off the electricity.

This type of submersible pump control box contains a capacitor relay and associated electronics. Two wire well pump wiring diagrams 2 wire well pump diagrams are slightly easier to understand and are more straight forward to wire.
