Wall outlet

Step 1: First and Foremost!

Locate which outlet needs replacing. Outlets need to be fixed if they have stopped working, have loosened, or look old and ugly.

Step 2: Locate Your Main Power Source

  • Once you have identified which outlet you will be replacing, you will need to locate the breaker box. The breaker box or fuse box will be far from the main living areas such as, in the basement, garage, or laundry room.
  • Turn off the switch to which outlet you will be replacing. It is crucial to make sure the circuit power cut off because some labels may not be accurate. You can check the power by using your voltage tester.
  • Plugin the outlet voltage tester, and if the light does not come on, then you are ready to replace your outlet.

A brief rundown of how to use an outlet voltage tester:

You will begin by inserting the end of the voltage tester in both straight slots of the live receptacle. There are different models of testers so depending on your model, the tester should flash, beep, or if there is a live current. If the outlet is wired correctly, the test will indicate voltage only when inserted in the short “hot” slot but not the long neutral slot or the rounded ground slot.

Step 3:

You will start by utilizing your flathead screwdriver to unscrew the screws holding the cover plate. Then you will take your flathead screwdriver to unscrew the top and bottom screw of the outlet. Some outlets may require a Philips head screwdriver. You may need to take your utility knife to score the paint from the edges. You will pull the outlet from the wall as far as the wires can reach.

Step 4: Time To Strip!

Here you will utilize your wire strippers to strip of insulation to reveal the wire. It will help remove the wires from the screws of the old outlet. You can find out how to use your wire strippers to strip the insulation from the copper wire in Step 5 of “How to Replace an Electrical Outlet”.

Step 5: Almost there!

  • With a 4-wire outlet, you will see two white and two black wires along with the ground wire. When replacing a 4-wire outlet, it is important which side of the plug the different color wires go on, but it is not essential which terminal they go on in the vertical direction. After the cables are disconnected, get your new plug.
  • In your house, there will either be 15-amp circuits or 20-amp circuits. It can be determined by either looking at the breaker for the room or look at the wire. If it is a 15-amp circuit, it will be 14-gauge wire, and you will need to purchase a 15-amp circuit plug.
  • If it is a 20-amp circuit, you will have to buy a 20-amp plug. One easy way to tell if you have a plug that will handle the load that the circuit is capable of is if the wiring from your house will go into the holes in the back of the plug. If the wiring is small enough to go into the holes, then you are okay.

Step 6: Make sure your outlet is in the upright position before landing the wires!

To connect the new outlet, you will start by putting the white wires on the same side that contains the ground screw. This side of the outlet is the neutral leg of the circuit; it is the silver side. Take the two white wires and press them into holes in the back of the plug on the right side.

Step 7:

Next, you will connect the ground wire around the ground screw. The ground screw will be green and underneath the two screws where you connected the two white wires. The ground wire should have a little hoop in it to hook around the screw. Once you have it hooked around, you can screw it, which will tighten the loop as well.

Step 8: Connect, Connect, Connect!

Next, you will connect the black wires. These are the hot wires. They go into the brass side of the plug—the side without the ground screw. You can even see the outlet itself, and the more elongated slot is the neutral or the white wire. The shorter space is the hot or the black wire. The bottom opening is the ground wire. You will press the black wires into the holes on the back of the plug.

Step 9: Back In The Wall You Go

Now the wires are back in the plug, and it is time to put it back into the wall. When you replace the plug into the box, be sure you fold the wires so that they can fold up into the box nicely. Also, make sure the ground wire does not get pushed up against any of the other terminals! Tighten the screws back just enough to press the receptacle against the wall gently.

Step 10: You have made it!

Lastly, install your cover plate. These will be the same, whether it is a 15-amp or 20-amp circuit. Locate your breaker box again and switch the power back on. Take your voltage tester to make sure everything is connected correctly. If the light comes on, then you have completed the installation of a 4-wire electrical outlet.
