How To Add an Electrical Outlet Between Two Existing Outlets

Adding an electrical outlet between two existing outlets can seem like a daunting task, especially for those who have little or no experience with electrical work. However, with the right tools, materials, and instructions, this task can be accomplished safely and effectively. This comprehensive guide will provide you with step-by-step instructions on how to add an electrical outlet between two existing outlets.

Safety Precautions

Before we delve into the process, let’s discuss the safety precautions to take when working with electricity and installing a new outlet. Always remember to:

• Turn off the power at the main circuit breaker or fuse box.
• Use insulated tools and avoid working with electricity when your hands or feet are wet.
• Inspect all equipment, cords, and plugs for damage before use.
• Follow local electrical codes and safety rules.
• Seek professional help if unsure about any aspect of the installation.

Tools and Materials Needed

To add an electrical outlet between two existing outlets, you will need the following tools and materials:

• Electrical cable with ground (14-gauge for a 15-amp circuit)
• New outlet
• Old work electrical box
• Screwdriver
• Wire stripper
• Drywall saw
• Wire coat hanger or fish tape
• Wire connectors

Step-by-Step Guide

Step 1: Turn Off the Power

Before starting any electrical work, make sure to turn off the power at the main circuit breaker or fuse box to avoid electrical shock. Use a voltage tester to confirm that the power is off.

Step 2: Locate the Existing Outlets

Identify the two existing outlets you want to add the new outlet between. Make sure there is enough space between them to accommodate the new outlet.

Step 3: Cut a Hole in the Wall

Use a drywall saw or utility knife to cut a hole in the wall for the new outlet box. The hole should be large enough for the box to fit snugly.

Step 4: Run the Cable

Run a new cable (either 14-2 or 12-2, depending on the load you need) from one of the existing outlets to the new outlet location. You may need to drill holes in the wall studs to pass the cable through.

Step 5: Install the New Outlet Box

Insert the new cable into the outlet box, making sure the cable sheath extends about one inch into the box. Secure the box to the wall using the provided mounting screws or clips.

Step 6: Wire the New Outlet

Strip the insulation from the wires in the new cable. Connect the white (neutral) wire to a silver-colored terminal screw, the black (hot) wire to a gold-colored terminal screw, and the bare copper (ground) wire to the green screw on the new outlet. Make sure the connections are tight and secure.

Step 7: Connect the New Cable to the Existing Outlet

At the existing outlet, disconnect the wires from the outlet terminals. Splice the new cable’s wires to the corresponding wires from the existing outlet, using wire nuts or other appropriate connectors. Reconnect the spliced wires to the outlet terminals.

Step 8: Install the New Outlet

Secure the new outlet in the junction box, ensuring the wires are properly connected and folded back into the box. Attach the faceplate to complete the installation.

Step 9: Test the New Outlet

Turn the power back on at the circuit breaker or fuse box and use a voltage tester or plug in a device to ensure the new outlet is functioning correctly.

Common Mistakes to Avoid

When installing a new outlet, some common mistakes to avoid include not grounding the outlet, installing loose outlets, reversing wires, using backstab connections, not turning off the breaker, and connecting the wrong wire to the wrong terminal.

Necessary Checks for Proper Functioning

After installation, ensure the new outlet is functioning properly and safely by measuring the voltage, checking proper grounding, conducting a polarity test, inspecting the outlet cover, childproofing if necessary, and checking for signs of wear or damage.

Conclusion

While it is possible to add an electrical outlet between two existing outlets by yourself, it is always recommended to hire a professional electrician if you are not confident in your abilities. Working with electricity can be dangerous, and professional electricians have the necessary experience and tools to ensure the job is done safely and correctly. However, if you decide to take on this project, this guide will provide you with the necessary steps to successfully add an electrical outlet between two existing outlets.
