Installing outlets under kitchen cabinets can significantly enhance the functionality of your kitchen space, allowing you to plugin countertop appliances without relying on extension cords. This straightforward DIY project requires basic electrical knowledge. If you’re not comfortable working with electrical components, we recommend hiring a professional electrician.
Before starting, always ensure you turn off the power at your home’s main electrical panel. Use a voltage tester to double-check that the power is off before proceeding. Safety first! This article will guide you through the process of installing outlets under your kitchen cabinets.
Preparation and Planning
An effective installation begins with accurate planning and preparation. Measure the exact location for your new outlet, considering the size and placement of your cabinets. Ensure it’s convenient for your device’s cord to reach without straining.
Before purchasing supplies, confirm with your local building codes and obtain any necessary permits. In some areas, you may need a permit for electrical work. Gather all the required materials: a line Voltage Meter, Fish Tape, Circuit Breaker (if needed), Outlet Box, GFCI Outlet, Wire Nuts, Romex Wiring, and a BoxNothing tool for accessing tight spaces.
Understanding Your Circuit
Before you start any work, understand which circuit you’ll connect to. GFCI outlets in kitchens usually share a 20-amp circuit with the lighting. TheExisting Wire helper app can help you identify the circuit by displaying the wire’s color.
If you’re connecting to an existing outlet, ensure you pull the right amount of wire. For a 20-amp circuit, you’ll need 12/2 or 14/2 non-metallic sheathed cable (Romex). Double-check that the new wire is long enough to extend from your existing outlet to the new one.
Planning Your Wiring Path
Before fishing your wires, plan your route. The wire should run perpendicular to studs and not alongside them to avoid damage during drywall installation. Use your Fish Tape to pull through and test this path. If you encounter obstacles, modify your route.
Consider upgrading to a new 20-amp circuit if you have enough space. This allows for more power and is nationally required for new kitchen installations. Contact a professional electrician to help if you’re unsure.
Installing the New Outlet Box
Once your path is clear, it’s time to install the outlet box. Its size will depend on your cabinet’s thickness and the required GFCI outlet. Use screws or awaldlath to attach the box to the cabinet underside, ensuring it’s level and securely fastened.
Next, measure and cut the Romex wire, ensuring it’s long enough to reach the existing outlet, diversity to the new box, and an extra foot to accommodate possible future changes.
Wiring the Outlet Box
Strip the wires inside the new outlet box, leaving about an inch of exposed wire. Connect the black (hot) wire to the brass-colored terminal on the new GFCI outlet. Connect the white (neutral) wire to the silver-colored terminal.
For the ground wire (green or bare), connect it to the green terminal on the GFCI. Now, run the wires through the cabinet to the existing outlet, keeping them tidy and secure. Ensure your cabinet door can still open fully and close without obstruction.
Connecting to the Existing Circuit
Back at the existing outlet, turn off the power using your multimeter to confirm it’s off. Strip the wires and connect them to the new wire: black to black, white to white, and ground to ground. Secure each connection with a wire nut.
Connect the neutral wire from the new outlet to the neutral bus terminal in the panel. Ensure the hot wire is connected correctly, and the ground wire is connected to the ground bus. Finally, reattach the panel cover and turn the power back on.
Testing and Final Touches
Before plugging in any devices, test the new outlet using a multimeter. It should read 120 volts between the hot and neutral terminals, and zero volts between hot and ground.
Now, press the TEST button on the GFCI outlet. The RESET button should pop out. Press RESET, and your new outlet is ready to use. Install a cabinet guard to protect the wire and outlet from damage when the cabinet door closes.
Regularly test your GFCI outlet to ensure it’s working correctly. Over time, electrical components can fail, and testing helps prevent accidents.
Enjoy your newly installed under-cabinet outlets! They’ll not only enhance your kitchen’s functionality but also add a modern touch. If you have any doubts during the process, don’t hesitate to contact a professional electrician for advice or assistance.
