How to Install a Dimmer Switch

Tools to get started

Before you begin, you'll need these tools:

• Flat-head screwdriver (the kind with a tip that’s a straight line)
• Phillips-head screwdriver (the X-tip kind)
• Electrical tape
• Needle-nose pliers
• Wire stripper
• Red wire nuts
• Dimmer switch
• Matching cover plate

Tip: Don’t use a dimmer on a circuit that includes an outlet. You could damage such products as vacuums and electronic devices if they’re plugged into a dimmed outlet.
