Step by Step Process of Running Extension Cord: Inside to Outside!

Not only for yard parties but you sometimes also need to add a generator outside! For this, you will need to learn the process of extending the extension cord outside! But first, check the right generator extension cords and pick up the right one! And then, follow this step-by-step process and have fun!

Step 1: The Locator Hole

Once you have decided to run the extension cord from inside to outside, you have to purchase the right extension cord. The larger the cord, the more the safety! You can look into the 12 gauge extension cords as they provide amplified protection when it comes to the outdoor.

After that, you need to search the cable path. In this case, we suggest you find the easiest path. All you need is your cable to reach the outside wall! You can also check the crawlspace too! When you have found the area, you have to start drilling and get a locator hole. Always remember that you need a long drill for the job.

If you mistakenly drill a place, all you need is to get a LEB fitting search for another area to run the power! Once you get it, go for the same drill and drill a locator hole there.

Step 2: Adding the Remodel Box

You have already made a locator hole in your preferred area. Now, you have to place the remodel box here. If you have done it before, you already know how to do it. But for the newbie, we will discuss it in short. Here, you will need a reciprocating saw.

If you don’t have one you can also get your hands on a keyhole saw. Now, all you need to do is cut a hole in the box! After cutting the hole for the remodel box, you need to get the cable through that hole. And eventually, the hole will take the cable to a remodel box.

After you have run taking the cable, move forward to installing the box carefully. An additional extension ring is required here. Also, if you are using PVC, you will need a terminal adapter. Prepare all your necessities before you sit for work. 

Step 3: Dig below the Box

Now, go to the outside wall and check if the box is installed properly or not. Here, check under the box. You have to dig a trench here! Yes, you heard what we said! Right below the box, you have to dig a trench for the local codes.

However, ensure that there will be no trouble in the future for digging that specific area. In this position, you will need PVC. In other cases, you can settle for rigid metal conduit too.

All you need is to add the length of the pipe to a sweep! First, with the help of the necessary gear, you have to cut it. Then you need to add it and then with the help of straps, you must anchor the conduit!

Step 4: Work with the Wires

You are almost done; all you got to do now is to connect the wires! First, go through the power circuit and shut off the power. Then, check the black and white wires. You have to connect them carefully. These will start at the power source and will go to the LINE terminals of the GFCI receptacle.

Once you are done running the cable, you have to add the wires to the LOAD terminals! In this way, you can certify GFCI-protected service. Now, you are done, you have to go through the power circuit and connect the power.

Step 5: Cover it up

Once you have connected the power, you can add the cover of the box. The in-use cover can help you in the long run. This will keep the receptacle safe from water or moisture from the outside. Even if the cord is connected and there is moisture outside, it can safeguard your receptacle without any complication! And now, it is time for you to enjoy any outdoor party with lights and necessary attachments outside!

Extension Cord Safety

Before everything, when it comes to run the extension cord outside, you have to follow some safety rules to keep you and your property safe.

  • The first job is to get your hands on the cord that is right for the work. Keep in mind that different cords are designed differently to fit different areas. In that case, one cord will not settle with everything. It is better that you pick up a cord that can work with every connected device’s wattage. It should have the ratings that you prefer. If the wire is large, it is capable of handling the current more safely. If the wire is small, it has a limited capability of handling the current safely.
  • The right length for the cord is always recommended. No short cords are allowed on the job. Some people think that keeping a cord those lengths more than necessary is helpful. But it will be a threat to the safety and also, there can be tripping hazards too! So, the right length is always necessary for this job.
  • The outdoor extension cord requires a GFCI outlet. No matter how much you deny, you should not plug your outdoor extension cords just the way you plug the indoor ones. You can get these by checking the TEST/RESET buttons. If you check your kitchen, you surely will get some of these there. Also, these are set mostly in your garage and the bath. No matter you are in the garage, kitchen, or bathroom, the cords can easily get exposed to water. In that case, such outlets will help keep them shock-proof!
  • After you are done with outdoor partying or outdoor family time, you must unplug the extension cord. Once you are done unplugging, you have to store that carefully. Never store it outside, instead, store it inside and keep it safe.
