Basic Control Circuit to Operate Well Pumps
Electrical Question: I have two water wells and both produce too little on their own to provide sufficient water for our home.

• They are almost identical in every way, including the submersible pumps and pressure switches.
• Each has its own 220v 30a breaker and circuit.
• Can I combine into one circuit, increase that circuit’s breaker to 60a, wire that single circuit into a single pressure switch, have two circuits come off the pressure switch (one to each pump) and put a 30a breaker on each of these circuits between the single pressure switch and their respective pumps?

Thanks for your electrical wiring question Scott.

### How to Build a Control Circuit to Operate Two Well Pumps

Controlling Two Well Pumps

• You can accomplish this type of control for two well pumps simply by using a basic control circuit that would run through the pressure switches and activate 30 amp rated motor controls (larger relays) which would start or stop the pumps.
• The control circuit could be a 120 or 240 volt protected circuit which may be powered by a transformer which is wired to the primary side of one of the pump circuits or it could be a separate circuit.

## The Safest Way to Test Electrical Devices and Identify Electric Wires!

The Non-Contact Electrical Tester
This is a testing tool that I have had in my personal electrical tool pouch for years, and is the first test tool I grab to help identify electrical wiring. It is a Non-contact tester that I use to easily Detect Voltage in Cables, Cords, Circuit Breakers, Lighting Fixtures, Switches, Outlets and Wires. Simply insert the end of the tester into an outlet, lamp socket, or hold the end of the tester against the wire you wish to test. Very handy and easy to use.

## The Quickest Way to Check for Faulty Electrical Wiring!

The Plug-In Outlet Tester
This is the first tool I grab to troubleshoot a problem with outlet circuit wiring. This popular tester is also used by most inspectors to test for power and check the polarity of circuit wiring.
It detects probable improper wiring conditions in standard 110-125 VAC outlets Provides 6 probable wiring conditions that are quick and easy to read for ultimate efficiency Lights indicate if wiring is correct and indicator light chart is included Tests standard 3-wire outlets UL Listed Light indicates if wiring is incorrect Very handy and easy to use.

## Strip Off Wire Insulation without Nicking and Damaging the Electric Wire!

The Wire Stripper and Wire Cutter
My absolute favorite wire stripping tool that I have had in my personal electrical tool pouch for years, and this is the tool I use to safely strip electrical wires.
This handy tool has multiple uses:
The wire gauges are shown on the side of the tool so you know which slot to use for stripping insulation.
The end of the tool can be used to grip and bend wire which is handy for attaching wire onto the screw terminals of switches and outlets..

The wire stripper will work on both solid and stranded wire. This tool is Very Handy and Easy to Use.
