How to Protect Outdoor Extension Cord from Rain?

How to Protect Outdoor Extension Cord from Rain
Written by Jamie Masterson

Keeping outdoor extension cords dry requires covering them. There are many ways to do this from cord covers to tape and plastic containers.

Choose from the methods below for a way to keep your cords dry.

How to Protect Outdoor Extension Cord From Rain

Method 1: Tupperware

Tupperware method

Step 1: Locate a plastic container large enough to hold all or majority of your extension cord. This method works best when the box is long and thin.

Step 2: Drill holes in both sides of the container with a drill. Don’t make these holes too wide because the cable will need to fit snugly into them.

Step 3: Cut out the holes with a knife. You can use a knife to make them wider if they are too narrow at this point.

Step 4: Stuff the box with the cord. Put electrical tape over the holes and thread the cord through.

Method 2: Plastic bag

Step 1: Obtain a few heavy-duty plastic bags. You need thick bags, not supermarket ones. Make sure you have enough bags to cover the entire cable.

Step 2: Attach the bags with tape, leaving small holes at either end for cable access. Every connection point needs to be watertight and airtight.

Method 3: Extension cord protective kit

Plug/extension outlets are protected with watertight seals by cord connect products. As a result, the plugs are also protected from separating, which ensures you’ll be able to work without worrying about weather damage to your connections.

Each end of the cord should be wrapped around the casing, and then the cords should be twisted together to make a weatherproof seal.

Method 4: Used pool noodle

Step 1: Make sure you have enough pool noodles to enclose the cord. Cut the noodles to sizes that fit your cord.

Step 2: Slice open the pool noodles like you would a hotdog bun.

Step 3: Push the cable through the noodle and tape it back up.

Method 5: Secure the extension cord

A decent electrical tape is all you need to tape the extension cord. All you have to do is wrap the tape around your extension cord.  This will deflect the rain.

Make sure the tape is firmly attached, rewinding it repeatedly. This type of electric tape is typically waterproof.

Method 6: The bucket method

The bucket method

A shovel and two buckets are needed for this method.

First, you set one bucket on the ground, set the cords connected to the bucket on top, and then place the bucket so the opening faces the ground.

Place the opening of the second bucket facing the ground, then slide the second bucket onto the first.

Method 7: The bottle method

Christmas lights can be covered using this method, as well as connections. You will need a 2-liter soda bottle to accomplish this method.

It is necessary to have a utility knife and scissors, tools with sharp edges capable of cutting through bottles.

  • Using your sharp-edged tool, make a half-way cut in the bottle. Around the bottle, the cut should be 1/4″ wide.
  • At the end of the slit, use the scissors to make a round hole, so the cord will stay in place.
  • Connect the plugs and connections to the bottle safely, letting the cords extend from the holes.

Method 7: PVC pipes and end-caps

This method is a little more complex so we have added a video to help you along the way!

Rain Protection for Outdoor Extension Cords

  • Firstly, they’re only useful if they’re intended to be. Make use of them temporarily
  • Make sure it is fully plugged in before using it. Plug the cord into your device afterwards
  • It should be rolled up after use and stored in a safe, dry location
  • Before you use the cord, make sure it is not damaged

Don’t Do These Things to Shield Outdoor Extension Cords From Rain

  • If your cord is too short to reach the outlet, move your device closer to that outlet or get another outlet. Make sure the surrounding area is safe
  • Electric wiring should always be used instead of extension cords. If you can’t then keep them underground, buried in walls, floors, and ceilings
  • To prevent fire hazards, do not use them through window openings or doorways
  • As much as possible, refrain from nailing and stapling power cords onto the surfaces and walls. Doing so will give you an electric shock

What to Do If Water Gets Into My Extension Cord

A fire does not occur

Despite the absence of a fire, you or others can still be injured. Make sure everyone is away from the area. Unplug the cord or turn off the breaker to turn off the power.

Once the cord has been disconnected, you can proceed to dry it.

If it catches fire

The first job would be to make sure that you and everybody around you are safe. If the cord catches fire due to the water, you’ll need to cautiously unplug the extension cord, and then you can douse the fire with water or flour.

If the fire blocks your access to the plug, use baking soda or a Class C fire extinguisher if available. Never use water in case the cord stays plugged in. If you think the fire is going to get out of hand, call 911 immediately.

Outdoor Extension Cord Protection Tips

Never extend a cord beyond its maximum length

To use an electrical cord safely, keep it close to the outlet if you can. The outlet and plug should be kept away from water and precipitation.

Always leave some slack in the cord, and, if you can, use a tie to secure the cord.

Keep your cords dry

Avoid putting cords in puddles, especially the section close to the connection, which could be damaged by precipitation.

Protecting your cords with cord protectors and following the steps outlined in the article will help to keep your cords dry and prevent electrocution.

If the cord is wet, do not plug it in, and never plug it into a wet outlet. You could get shocked and/or seriously injured.

Never step on a cord

When electrical cords are used outside, they are more likely to be driven over or stepped on. Avoid doing these at any cost.

Leaving cords lying around is not a good idea, for instance, due to heavy vehicles tearing the cord and exposing you to the danger of open or frayed cords.

When a vehicle is heavy, the cord is severely strained and cannot function properly. It is best not to use cords outside when heavy vehicles are present.

Also, make sure your children and pets don’t step on them accidentally.


Q. How to run extension cord from inside to outside?

If possible, it’s always a good idea to use extension cords intended for outdoor use, as they are made from materials resistant to moisture, the sun, temperature changes, along with foot traffic.

A good extension cord should be routed through areas where there isn’t much traffic. It is important to follow this safety tip to prevent trips and falls.
