20 Amp Double Pole Switch Wiring Diagram: The Ultimate Guide

Do you need to wire a 20 amp double pole switch but don’t know where to start? Look no further than this comprehensive guide to wiring a 20 amp double pole switch. Whether you’re a seasoned electrician or a DIY enthusiast, this article will help you understand the wiring process and get your switch up and running in no time.

What is a 20 Amp Double Pole Switch?

Before we dive into the wiring process, let’s first define what a 20 amp double pole switch is. A double pole switch is a type of switch that controls two separate circuits. In other words, it has two separate “throw” mechanisms that can switch both circuits on and off simultaneously. A 20 amp double pole switch, as the name suggests, is a switch that can handle up to 20 amps of electrical current. It is typically used in high-power applications, such as air conditioning units, hot water heaters, and electric car charging stations.

What are the Benefits of a 20 Amp Double Pole Switch?

There are several benefits to using a 20 amp double pole switch in your electrical system. First, it allows you to control two separate circuits with one switch, which can save space in your electrical panel. Additionally, it can handle high-power applications and can provide added safety by cutting off power to both circuits if necessary.

What Tools and Supplies Do You Need?

Before you begin wiring your 20 amp double pole switch, you’ll need a few tools and supplies. Here’s a list of what you’ll need:

  • Wire strippers
  • Needle-nose pliers
  • Screwdrivers
  • 20 amp double pole switch
  • Wire connectors
  • Electrical tape
  • Wire nuts

Wiring a 20 Amp Double Pole Switch: Step-by-Step Guide

Now that you have your tools and supplies, it’s time to start wiring your 20 amp double pole switch. Follow these steps for a smooth and successful installation:

Step 1: Turn Off Power to the Circuit

Before you begin any electrical work, it’s important to turn off power to the circuit you’ll be working on. Locate the circuit breaker that controls the circuit and flip it to the “off” position.

Step 2: Remove the Switch Plate

Next, remove the switch plate from the wall to expose the wiring behind it. Use a screwdriver to remove the screws that hold the switch plate in place.

Step 3: Remove the Existing Switch

If you’re replacing an existing switch, you’ll need to remove it from the wall. Use a screwdriver to remove the screws that hold the switch in place, and gently pull the switch out of the wall.

Step 4: Prepare the Wires

Once you’ve removed the switch, you’ll need to prepare the wires for the new switch. Use wire strippers to strip about 1/2 inch of insulation from the ends of the wires.

Step 5: Connect the Wires to the Switch

Connect the wires to the switch according to the wiring diagram that came with the switch. Typically, the black wires will connect to the brass screws, while the white wires will connect to the silver screws. The green or bare wire will connect to the green screw.

Step 6: Attach the Switch to the Wall

Once the wires are connected, attach the switch to the wall using the screws provided with the switch.

Step 7: Secure the Switch Plate

Finally, reattach the switch plate and secure it with the screws that you removed earlier.
