Changing old electrical sockets is a straightforward job that can be done by most DIYers. However, it is important to prioritise safety and ensure you are comfortable working with electrical wires. Before starting, make sure to turn off the electricity and put on the proper protective equipment, including closed-toe shoes, long pants, a long-sleeve shirt, insulated gloves, and safety glasses. If you are unsure about any part of the process, it is best to consult a professional electrician. When replacing an electrical socket, it is important to wire the new receptacle in the same way as the old one, ensuring that each wire is connected to the correct terminal. You can use a multimeter or voltage tester to check if the outlet is live and confirm that the power is off. Once the new socket is wired correctly, gently push it back into the box, tighten the mounting screws, and restore power.

What You'll Learn
Turn off the power at the breaker box
Before starting work on replacing an electrical outlet, it is important to turn off the power at the breaker box. This is the most important step in the project, as it stops accidental electrocution and prevents power surges, voltage fluctuations, and short circuits.
To do this, first locate your breaker box, also known as an electrical panel or fuse box. This is usually located in a utility closet or basement, and will contain a labelled chart indicating which room or appliance each switch corresponds to. Once you have located the correct switch, flip it to the off position. This will cut the power supply to the outlet you are replacing.
It is important to double-check that the power is off by testing the outlet with a voltage tester. If the outlet is still live, you may have flipped the wrong breaker switch. In this case, turn the power back on, and try again. Alternatively, you may need to turn off both circuits if your outlet has separate circuits for the top and bottom plug.
If you are not comfortable working on electrical systems, it is best to call a professional electrician.

Disconnect the wires
Before disconnecting the wires, it is important to ensure that you are comfortable working with electrical wires and that you have turned off the electricity. It is also a good idea to test and confirm that the outlet is no longer live. You can use a voltage tester or plug in a lamp to double-check.
Now, to disconnect the wires, use a screwdriver to loosen the screws connecting the wires and the outlet. If you need to remove the wires from the old outlet, you can simply cut them off and re-strip for the new outlet. However, if you plan to reuse the wires, use wire strippers to trim any frayed, worn, or damaged sections. This will help prevent shorts or connectivity problems with the new outlet.
If the wiring looks to be in good condition, you can leave it as is and proceed with the installation of the new outlet. Remember to attach the wires in the same configuration as they were connected to the old outlet. Refer to any pictures or videos you took before disconnecting the wires.
Once the wires are securely connected to the new outlet, wrap them with electrical tape to cover all terminals and bare wire sections.

Attach new outlet
Before you begin, ensure you are comfortable working with electrical wires and that you have the proper protective equipment, including closed-toe shoes, long pants, a long-sleeve shirt, insulated gloves, and safety glasses. Avoid wearing any loose jewellery or clothing.
Now, attach the wires to the new outlet. The black wire should be connected to the brass terminal, the white wire to the silver terminal, and the ground wire to the grounding screw at the back of the box and then to the green screw on the outlet. You can refer to the pictures or videos you took earlier of the wire configuration in the old outlet.
Once the wires are attached, gently push the new outlet back into the box. Screw the new outlet in place and attach a new faceplate if the old one was cracked or damaged.
Finally, restore power and test the outlet with a voltage tester. If you don't have a voltage tester, you can plug in a lamp and turn it on to check if the outlet is working.

Gently push the outlet back into the box
When you are ready to gently push the outlet back into the box, it is important to remember to be careful and gentle. You should not force the outlet back into the box, as this could damage the outlet or the box itself. Use gentle but firm pressure to push the outlet back into the box, ensuring that it is securely seated and does not move around.
Before pushing the outlet back into the box, it is crucial to make sure that the wires are connected correctly and securely. Double-check that each wire is attached to the correct terminal and that there are no loose connections. It is also a good idea to wrap the terminals and any exposed wires with electrical tape for added insulation and protection.
If the outlet feels difficult to push back into the box, take a moment to inspect the connections and ensure that nothing is blocking the outlet. Make sure that the wires are not tangled or caught on anything, and gently adjust the outlet's position if necessary.
Once the outlet is securely seated in the box, you can tighten the mounting screws to secure it in place. Use a screwdriver to tighten the screws, being careful not to overtighten them. This will help ensure that the outlet is securely attached and reduce the risk of it coming loose over time.
After tightening the screws, take a moment to check that the outlet is straight and level. A crooked outlet can be unsightly and may indicate that the outlet is not securely attached. Gently adjust the outlet's position if needed and tighten the screws again until it is securely in place and level.

Test the outlet with a voltage tester
Once you have replaced the old electrical outlet, it is important to test the new outlet with a voltage tester. Before you begin, make sure you are comfortable working with electrical wires. If not, it is best to call a professional electrician.
To test the outlet, first, turn off the power for the circuit at the breaker box. You can then test the outlet with a voltage tester to confirm that the power is off. If the voltage tester shows current, you may have flipped the wrong breaker switch.
If the power is off, you can then wire the new outlet. Attach the wires to the new outlet, ensuring that each wire is connected to the correct terminal. Wrap with electrical tape to cover all terminals and bare wires. Gently push the outlet back into the box. Tighten the mounting screws and check that the outlet is straight. Put the wall plate back on.
Once the outlet is wired, you can restore power and test the outlet with the voltage tester to ensure that it is working correctly.
