Take the black wire from the first receptacle and connect it to the black wire leading to the second receptacle using a wire nut.
-
Return any unused wires (such as if reusing an existing receptacle) back into the box securely.
Step 5: Secure the Receptacles in Their Boxes
Having made the necessary connections, proceed to neatly tuck in the wires back into the electrical boxes. Secure the new receptacles in place with screws, ensuring they are flush against the wall and properly aligned. Replace the cover plates carefully.
Step 6: Double Check Your Work
It’s crucial to ensure everything is connected correctly. Double-check that:
- All wire connections are secure and insulated with wire nuts.
- There are no exposed wires outside the boxes.
- The receptacles are mounted firmly.
Step 7: Restore Power and Test the Connection
Now that everything is in place, head to your circuit breaker panel and turn the power back on. Use a voltage tester on both receptacles to confirm they are functioning correctly. If they light up, congratulations—you’ve successfully connected two receptacles!
Common Mistakes to Avoid
Even though connecting receptacles is relatively simple, certain pitfalls can occur. Avoiding these mistakes can save you time and ensure safety:
Not Turning Off the Power
One of the most dangerous mistakes is failing to turn off the power. Always ensure the circuit is de-energized before working on your receptacles.
Improper Wire Connections
Improperly connecting the hot, neutral, and ground wires can lead to malfunctioning outlets or pose a fire hazard. Always refer back to the wiring configurations you noted and double-check your connections.
Conclusion
