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.
