What You'll Learn

Use a plastic container with a lid
Using a plastic container with a lid is a simple and effective way to keep electrical cords dry outside. This method is a great DIY solution, and it is customizable, depending on the length of your cords and the number of cords you need to keep dry.
To start, you will need a sturdy plastic container with a removable lid. Think about the size of the container and whether it will fit the number of cords you need to keep dry. You can use storage bins or even an unused ice cream tub.
Once you have your container, you will need to drill holes at each end, big enough for your cords to fit through, but not so big that rain can get in. Use a utility knife to widen the holes if necessary.
This method is a great way to keep your cords dry and protected from the elements. It is important to take precautions to keep electrical cords dry outside, as wet cords can cause shorts in your electrical devices or even lead to electric shock.
Additionally, you can use cord clips to secure your cord and prevent it from dragging on wet surfaces. This will further ensure that your cords stay dry and safe.

Seal cord connections with electrical tape
Electrical tape is a simple yet valuable tool for insulating electrical wires and other materials that conduct electricity. It is also useful for making minor repairs to damaged wires. When it comes to keeping electrical cords dry outside, sealing cord connections with electrical tape can be an effective method. Here are some detailed instructions to help you get started:
First, it is important to choose the right type of electrical tape. While there are various options available, self-fusing silicone tape is highly recommended for sealing cord connections. This type of tape adheres only to itself, creating a strong and durable seal that is resistant to water, dust, and air. It can withstand a wide range of temperatures and is easy to remove without leaving any sticky residue.
Before applying the tape, ensure that the connection is clean and dry. Any moisture or debris on the surface may compromise the effectiveness of the seal. Once you have prepared the surface, stretch the tape to three-quarters of its original width. This step is crucial for securing a moisture-tight seal. Start wrapping the tape around the connection, ensuring that each layer overlaps the previous one.
For added protection and insulation, consider using two layers of tape. First, apply a layer of self-bonding tape, which is made from rubber resin and provides excellent durability and resistance to tears and abrasion. Then, add two layers of vinyl electrical tape on top of the self-bonding tape. This combination will provide maximum protection against moisture and abrasion.
When sealing cord connections, it is essential to avoid using electrical tape as a permanent solution. Electrical tape is not designed to withstand the heat produced by electrical currents over an extended period. Therefore, it should only be used for temporary connections and repairs. Remember to verify the electrical and temperature ratings of the tape before application to ensure it is suitable for your specific needs.
By following these instructions and choosing the right type of electrical tape, you can effectively seal cord connections and keep your electrical cords dry outdoors. This will help prevent moisture damage and ensure the safe and proper functioning of your electrical equipment.

Avoid laying cords in low spots
Keeping electrical cords dry outside is important to prevent short circuits, electric shocks, and fires. One crucial step to achieving this is to avoid laying cords in low spots.
If you must lay your cord on the ground, it is important to ensure that it doesn't run through low spots or areas that are prone to flooding. By being mindful of how and where you route your extension cord, you can significantly reduce the risk of water damage. For instance, you can elevate the cord by hanging it or winding it around a hook to keep it off the ground. This is especially important if you live in an area that experiences heavy rainfall or flooding.
Another option is to create a DIY rain shelter by draping a plastic sheet over a frame and sealing the edges with duct tape. This will protect your cords from rain and moisture. You can also purchase waterproof cord covers or extension cord covers that are designed to keep water and debris out. These covers are adjustable and durable and will protect your cords from the elements.
Additionally, when purchasing an extension cord, opt for weatherproof cords with water-resistant plugs. These cords are designed with weather-resistant materials and have reinforced insulation and sealed plugs to keep moisture out. By investing in the right cords and being mindful of how you lay them out, you can effectively avoid water damage and keep your electrical cords dry outside.

Store cords in a dry location after use
Keeping electrical cords dry outside is essential for safety. Wet cords can quickly deteriorate, leading to frayed or damaged wires, which can cause electrical shorts and even fires. Therefore, it is crucial to store cords in a dry location after use.
- Choose a suitable storage location: Select a dry, indoor area that is protected from the elements. A shed, garage, or utility room can be ideal locations to store your cords when not in use. Ensure the space is well-ventilated and that the cords are not exposed to excessive heat or direct sunlight, as this can also damage the insulation over time.
- Use storage containers: Place the cords in sturdy plastic containers with tight-fitting lids. These containers will protect the cords from moisture and dirt. Drill holes at each end, large enough for the cords to pass through but small enough to prevent rainwater from entering. You can use a utility knife to adjust the size of the holes as needed.
- Keep them off the ground: If possible, store the cords on shelves or hang them on wall hooks. This will ensure they don't come into contact with any moisture or water on the floor. It's also a good idea to use cord clips or holders to keep them organised and off the ground.
- Label the containers: Clearly label the containers to indicate that they contain electrical cords. This will help you identify the contents easily and ensure that anyone handling the containers knows to keep them dry and handle them with care.
- Regularly inspect the cords: Before and after each use, inspect the cords for any signs of damage, such as frayed wires or broken insulation. Do not use damaged cords, as they can be unsafe and increase the risk of electrical hazards.
By following these steps, you can effectively store your electrical cords in a dry location, ensuring their longevity and safe usage.
