Control Wiring for a Water Pump With Energy Monitors
Question: How can I control one water pump from two different locations with two energy metersĀ  so that if the first switch is on the first energy meter will read the consumption, and the second switch will not function till the first switch is turn off and vice versa.

This electrical question came from: Debadutta, a Homeowner from Bhubaneswar, India.

Thanks for your electrical question Debadutta.
Wiring a Water Pump and Controls
Debadutta, this could be accomplished using two low voltage control switches which would activate a double pole, double throw relay or contactor. The power to the pump would be connected to the common terminals, one switch circuit and energy monitor would be connected to the normally open set of contacts, and the other switch circuit and energy monitor would be connected to the normally closed set of contacts. The main power would be ahead of the control relay to provide as the main on and off master power switch.

This section will cover the use of relays that are sometimes needed to control special device loads such as Generators, Air Conditioners and other high demand equipment. The content is explained through industrial controls but the principles can be easily adapted to residential wiring applications as well.

Electrical Tips to Help You Wire it Right

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.
