2 wire submersible well pump wiring diagram a newbie s overview of circuit diagrams.

Test 2 wire submersible well pump. Getting from point a to point b. Turn off the well s circuit breaker. Tests of the pump wiring are made by individually connecting between each wire at the well head and ground. On 3 wire motors measure the resistance of yellow to black main winding and yellow to red start winding.

The control box mounts to a wall next to the well s water storage tank. The purpose is the very same. The correct circuit breaker has a well label. I usually test for ampere draw at the wires at the well cap.

How to test a well pump control box step 1. Testing a franklin electric qd quick disconnect box qd boxes are designed for use with 3 wire single phase submersible motors from. Sometimes it s at the circuit panel or at the controller if there is one. Use next scale up for values over 10 ohms.

It shows the parts of the circuit as streamlined shapes and also the power and also signal connections between the devices.

In this video i go over the differences of a 2 wire and a 3 wire submersible well pump this is associated with the starting components for the pump and whet. A very first look at a circuit layout could be complicated however if you can review a subway map you could read schematics. There is usually a tag or decal on or near the well cap with pump motor specs. Troubleshooting inside the box is made simple by the control components automatically disconnecting from the system when the lid is removed.

A wiring diagram is a simplified standard pictorial representation of an electric circuit.
