Submersible Water Pump Electrical Wiring

Well pump wiring diagnosis repair.

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. We stock lengths of wire from 50 feet to 1000 feet in 8 10 and 12 gauge. It s often necessary to splice additional wires onto the installation before the pump gets lowered down below. 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.

Find submersible pump cable by the foot at lowe s today. This is what i. 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.

If it runs straight to the pressure switch it is a two wire. 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. 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. 3 phase submersible pump wiring diagram.

A wiring diagram is a streamlined traditional photographic representation of an electrical circuit. In which i control a three phase submersible pump motor using magnetic contactor. Well pump wire sizing information and maximum distances can be found in the franklin electric aim manual. Collection of 3 wire submersible pump wiring diagram.

How to wire a submersible well pump. It shows the elements of the circuit as simplified forms and also the power as well as signal links between the devices. And soldering these connections makes good sense. 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.

Ultimately using some simple electrical tests the homeowner traced the water pump problems to a nicked well pump wiring circuit wire.
