Submersible Water Pump Electrical Wiring

This article describes troubleshooting a submersible well pump that was causing tripped circuit breakers and that pumped water only at a slow reduced rate and pressure.

Submersible water pump electrical wiring.

It shows the elements of the circuit as simplified forms and also the power as well as signal links between the devices. 12 2 w ground flat hd submersible pump cable stranded copper for 2 wire pumps double jacketed ul listed tuhorse 5 0 out of 5 stars 2 23 00 23. If the conduit runs into a control box before continuing to the water pressure switch chances are you have a three wire pump. Submersible pumps come from the factory with a continuous length of wire attached to the motor but this isn t usually enough to get to the top of the well.

Well pump wiring diagnosis repair. Aqua science offers pvc submersible solid core twisted 2 and 3 wire with green ground wire for deep submersible pumps and double jacketed direct burial type uf b feeder wire. This is what i. Submersible pump wire is a multiconductor cable that connects a submersible pump controller to the motor of the pump which is often located in a deep well.

And soldering these connections makes good sense. Find submersible pump cable by the foot at lowe s today. 25 feet increment up to 1000 ft. If it runs straight to the pressure switch it is a two wire.

It s often necessary to splice additional wires onto the installation before the pump gets lowered down below. We stock lengths of wire from 50 feet to 1000 feet in 8 10 and 12 gauge. In which i control a three phase submersible pump motor using magnetic contactor. 3 phase submersible pump wiring diagram.

How to wire a submersible well pump. Collection of 3 wire submersible pump wiring diagram. 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. Not only a contactor but also i install the thermal overload relay which will protect the motor form burning in case of over current flow to the circuit.

Also known as sub pump wire it s protected by durable plastic insulation that resists oil lubricants acids ozone and abrasion making it ideal for wet or hostile environments.
