How to Add an Electrical Outlet From an Existing Light Switch?

Electrical Outlet Installation Services | Eagle Rock Residential Electricians

If you’re not new to electrical wiring repairs, you might want to do your electrical repair from a troubleshooting guide from one to time. Although it might look complicated at first, it is a good practice for simple electrical repairs since it has various applications and troubleshooting guides in pamphlets and on the internet. A three-way switch is easily added to the outlet for homeowners who want a convenient power source. Do not panic if you do not find neutral terminals in your outlets.

Unfortunately, the neutral wires are spliced together in wall switch wiring, which provides the switch box with a continuous path from fixture to power. The good thing is that hooking up an outlet doesn’t make that much difference from wiring it to any other power source. If you cannot find your main power source, it is better to ask for assistance from our crew at Eagle Rock Residential Electricians for electrical outlet installation services.

So you work more safely on the project, it is better to ask for help from your licensed electrician. These issues need safety precautions to avoid electrical shocks and other electrical hazards. You also need to ensure that there’s no voltage running across the circuit before attempting any do-it-yourself electrical project. It may also become more of a requirement if you’re dealing with GFCI outlets; these outlets are usually used for damp environments such as in bathrooms and swimming pool areas. 

In cases where your cable is too far from your switch, you may need to feed the cable to an attic or a basement. You might also need to remove the drywall and patch it up again after you’re running the cable in the room. Also, remember to use a cable with the same wire gauge as the cable with the switch. Not changing the wire gauge of an already installed room is recommended. After considering these pointers, you can follow the guideline below on adding an electrical outlet to an existing light switch.

  • Step 1: At the main electrical panel, disconnect the power supply from the light switch.
  • Step 2: Take off the switch plate and take the switch out of the outlet box by unscrewing it.
  • Step 3: You need to remove the switch from the box. It will be simple to add an outlet if a bundle of two white wires is linked behind the switch and two independent wires are running to the switch.
  • Step 4: Touch a voltage sensor to each wire individually to check that the power to the box has been turned off.
  • Step 5: Use electrical tape to mark the two wires connected to the switch and then cut the wires from the switch.
  • Step 6: Remove the current outlet box and install a new one.
  • Step 7: Disconnect the wire nut holding the two neutral wires together in the box’s back and add a third white wire to the mix. The new wires should be twisted together and capped with wire nuts. The new wire’s loose end should be connected to the outlet’s silver screw.
  • Step 8: Connect two brief black wires to the black wire previously attached to the switch’s gold screw. The hot wire ought to be this. The three wires should be twisted together and finished with a wire nut. One new wire’s loose end should be connected to the switch’s gold screw, while the loose end of the second new wire should be connected to the outlet’s gold screw.

How to Wire a Switch to a Plug Outlet?

Although a plug outlet is more traditional than your normal switch, it is still quite a hassle, especially for homeowners with limited electrical wiring knowledge. Here are some of the frequently asked questions regarding the wiring process of your switch to a plug outlet:

Should You Buy A Dimmer Switch?

Dimmer switches come in various designs and arrangements, including knobs, slides, and touch-sensitive dimming mechanisms. Check these essential details, though:

  • Capacity refers to how many lights it can control. Watts will be used to determine the capacity. To check if it is within the switch rating specified on the packaging or instructions, add the bulb wattages in all the switch control fixtures.
  • If only one switch controls the lights, get a “single-pole” switch; if two switches control the same lights, purchase a “three-way” switch.
  • Standard incandescent dimmers are needed for both regular and halogen lamps. You can use specific dimmer switches. A few fluorescent lights can also be dimmed, but not the majority. Special dimmers can also be necessary for low-voltage lighting.

Why Should You Not Reverse Hot and Neutral Wires?

A lethal shock can result from connecting the black hot wire to the neutral terminal of an outlet. The problem is that you may not realize you’ve made a mistake until someone is shocked because lights and most other plug-in devices will continue to function; they won’t function safely.

  • It would help if you connected the white wire to the neutral terminal of outlets and light fixtures at all times. The neutral terminal is always clearly labeled. A silver or light-colored screw is usually used to identify it. Join the hot wire to the opposite terminal. The ground is represented by a green or bare copper wire. Connect the ground to a ground wire, the ground box, or the green grounding screw.

Why Shouldn’t You Cut The Wires Too Short?

Unfortunately, wires cut too short make wire connections difficult and dangerous because they are more likely to fail. Allow the wires to protrude at least 3 inches from the container.

  • If you encounter short wires, there is a simple solution. Just add six inches of extension wires to the existing wires. These wire extensions are easily available at hardware stores and home improvement centers.

Do You Have Any Guidelines for Installation of A Three-Slot Receptacle Without A Ground?

It’s tempting to replace two-slot outlets with three-slot outlets so you can plug in three-prong plugs. However, only do this if you are certain that ground is available. Check the grounding of your outlet with a tester. A series of lights in the unit indicates whether the outlet is properly wired or if a fault exists. These low-cost testers are widely available at home improvement and hardware stores.

  • If you find a three-slot outlet in an ungrounded box, the simplest solution is to replace it with a two-slot outlet, as shown.

Do You Have Any Guidelines for A GFCI Outlet?

GFCI outlets protect you from a potentially fatal electric shock by shutting off the power when they detect slight differences in current. They are also commonly used in wet areas in your home. They have two terminal pairs. One pair labeled ‘line’ is for the GFCI outlet’s incoming power. The other set is labeled ‘load’ and protects your downstream outlets. However, if you mix up the line and load connections, you will lose the shock protection.
