DIY Methods On How To Protect Outdoor Extension Cord From Rain

There are several effective methods shown below, so you can pick any method you like and make your cords waterproof.

The Bottle Method

Covering Christmas lights with this method is useful, but you can also cover connections with it. 

Below are the instructions for this method

  • A pair of scissors and a utility knife (or box cutter), a sharp tool that can cut through a bottle, are required to gather.
  • Pick up an empty two-liter soda bottle. 
  • Take your sharp-edged tool and cut halfway through the bottle. About 1/4” should be the thickness of the cut.
  • At the end of the slit, use the scissors to make a hole that will hold the cord in place.
  • Put the connections and plugs inside the bottle safely, leaving the cords hanging out.

All you have to do is follow these three easy steps, and you are done. 

Use Cling Wrap

When you use extension cords outside, it is a good idea to weatherize your connections with pallet wrap.

The connection part of the cords should be tightly wrapped with plastic wrap to prevent water from entering and electric shock from occurring.

This method has the advantage of not only being effective as a standalone method but it can also be used in conjunction with other methods listed in the article to protect even further.

Power Cord Protector

Power Cord Protector

An inner tube made of rubber, not inflatable, is all you need for this method. 

  • One end of the inner tube should be cut open, and 
  • Insert the extension cord inside. 
  • The tube should be covered as much as possible, slid through, 
  • Take the other end of the inner tube and cut it off. 
  • To secure the extension cord to the inner tube, electrical tape is highly recommended (but optional).

Plastic Bags

Plastic bags are needed for this method. Use a name-brand bag instead of a reusable plastic bag from the grocery store.

Wrapping the bags around the cord and installing electrical tape is one option, or cutting the bags into smaller pieces and installing electrical tape as well.

The length of your extension cord and the amount of exposed cable will determine how long it has to be.

Power Cord Shield

For this method, you probably already have everything you require. A container, a drill, and a knife are all you require.

  • The extension cord should be protected (as much as possible) by a container. To compensate for this, however, a much bigger container must be used with a thicker and longer extension cord. 
  • Your extension cord should fit in a container. The size of the ones you need to use depends on the width and length of your container.
  • Make holes in the container on opposite sides with a drill. 
  • After that, you will slide a cord through both holes on either side and then extend it if necessary (once again, you should use a cord that is in good condition.) 
  • Adjust the cord as needed, as well as the container.
  • The hole can be adjusted with the knife as necessary. The connections need to be firmly secured inside the container or tote.

Rain and humid weather can’t harm you this way. Just use electrical tape or duct tape. Metallic tape could cause problems down the road.

Be sure that the lid is tightly fastened and, obviously, don’t leave the cord near puddles.

The Bucket Method

The tool needed for this method is a shovel and two buckets.

  • The first step is to place a bucket on the ground
  • The cords are connected at one end and the other end is placed over the first bucket, which is positioned with the opening facing the ground. 
  • Once this is done, slide the second bucket on top of the first, facing the opening down towards the ground.
  • To prevent wind from blowing the first bucket away, dig a tight-fitting hole around it using a shovel.
  • You should slide the first bucket into the ground, push it as deep as you can, and then do the other two steps. 

Pool Noodle

The method is cheaper and easier to use. 

  • Cover your extension cord with the appropriate amount of pool noodles. Slice the pool noodles as needed. 
  • Cut the pool noodles into the shape of hot dog buns. 
  • Wrap the pool noodle with electrical tape after inserting the cable.
  • Electrical tape should also be used to seal the noodles’ ends. 

This is a very simple trick, yet it works extremely well. Also, it makes tripping over the cord a little less painful.

What Should You Do 

Extension cables are too fearful to be used outdoors by many people. You and your family can stay safe by heeding the following advice: 

  • You should not rely on extension cords for a long-term solution. Make sure that the extension cords do not sit outside overnight. 
  • Take the plug out of the outlet, not just turn them off at the wall.
  • It’s always a good idea to check your cords before you use them, particularly if you’re going outside 
  • In addition to keeping extension cords dry outdoors, keeping them dry inside is equally important
  • Before you plug anything else into the cord, make sure it is fully attached to the wall

What Should You Don’t

As you review some of the most important safety tips above. Here are a few things you should never do with extension cords:

  • Use staples, nails, or any other object that will not pierce the cable when attaching extension cords to walls and floors. Avoid doing this while the cable is in use.
  • Using extension cords instead of traditional wiring is not recommended. Plug them in at an outlet, never behind a wall or under the floor. 
  • Extension cords should be kept away from doorways, windows, and other places where they could be a fire hazard or a tripping hazard.
  • Don’t connect them to a water source
  • Cables should not be stretched. Use a longer cord or move the items closer to the outlet if the cords are too short for your needs.
