How to Wire a 220 Volt Pump Switch




Pump Switch Question:
I would like to wire a wall switch for 220 Volt pump. I would like to shut the pump circuit off without having to flip the breaker. I was wondering if you have to break both legs of the circuit power or just one.
Thanks, Max.

Important Notice about Wiring Switches:
A switch should disconnect all of the power to the device or equipment.

Lower voltage circuits are commonly used to control line voltage contactor relays which control the power to a motor or other large equipment.

Hi Max - Great Electrical Repair Question!
This is a great concern - Yes, you should use a 2-pole switch rated for the amperage of the circuit which will turn off both legs of power. This way both legs of power will be disconnected. This is a very good safety because if anyone goes to work on the pump the power really will be turned off.

Do-it-yourself electrical switches projects can be rewarding, but please be careful!

Always make sure the circuit is off. NEVER work on live electrical circuits.

Electrical Tip

The Safest Way to Test Electrical Devices and Identify Electric Wiring!

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, [amazon.com], I use for the detection of Standard 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.
