Can outdoor extension cords be left outside?
When it comes to outdoor extension cords, it’s essential to know how to use them safely. Ignoring proper care can lead to damage, short circuits, or worse.
Outdoor extension cords can be left outside, but only if they are designed for outdoor use and managed properly to prevent hazards.
Leaving extension cords outside isn’t always straightforward. There are specific considerations that ensure they remain safe and functional in outdoor conditions.
Can you leave outdoor extension cords outside?
Leaving outdoor extension cords outside is common, but not every cord is suitable for outdoor conditions.
Yes, you can leave outdoor extension cords outside if they are rated for outdoor use and properly maintained.
Outdoor-rated extension cords are specifically designed to withstand UV rays, moisture, and temperature fluctuations. However, even these cords need attention to avoid wear and tear over time.
Why are outdoor-rated cords different?
Outdoor extension cords differ from indoor ones in material and design. They typically have durable, weather-resistant jackets made of materials like thermoplastic or rubber. These jackets shield the internal wires from moisture and other elements.
| Feature | Indoor Cords | Outdoor Cords |
|---|---|---|
| Material | Thin plastic or vinyl | Thick rubber or thermoplastic |
| Weather Resistance | Not resistant | UV, water, and temperature resistant |
| Usage | Light-duty appliances | Heavy-duty outdoor tools and equipment |
Practical tips for leaving cords outside
- Choose the right cord: Always check the rating on the cord to ensure it’s suitable for outdoor use. Look for cords marked with "W" or "Outdoor Use."
- Avoid prolonged exposure: Even outdoor cords can degrade under constant exposure to sunlight and moisture.
- Inspect regularly: Check for cracks, fraying, or other damage to prevent potential safety hazards.
Can outdoor extension cords get rained on?
Outdoor environments often bring rain, raising the question of safety during wet conditions.
Yes, outdoor extension cords can get rained on if they are designed to be water-resistant, but precautions are still necessary.
The role of water resistance
Outdoor extension cords are typically water-resistant, but not entirely waterproof. This means they can handle light exposure to rain but should not be submerged in water.
If water seeps into the connection points or cord itself, it could result in a short circuit or electric shock. Using covers or protective housings around connection points can mitigate these risks.
How to protect outdoor cords from rain
- Elevate connections: Keep plugs and sockets off the ground to prevent water pooling around them.
- Use waterproof covers: Enclose plug connections in weatherproof housing for added protection.
- Unplug during heavy rain: If the weather turns extreme, it’s better to unplug the cord to avoid accidents.
Signs of water damage
If your extension cord is exposed to heavy rain, inspect it for the following signs of damage:
- Burn marks near the plug or socket
- Unusual stiffness or brittleness
- Visible cracks or cuts in the insulation
What type of extension cord can be left outside?
Not all extension cords are created equal. Choosing the right type ensures durability and safety.
Extension cords rated for outdoor use, with features like UV resistance and heavy-duty insulation, are ideal for leaving outside.
Key features of outdoor cords
Outdoor-rated extension cords usually come with several features that make them suitable for external use:
- Thicker insulation: Protects against physical damage and environmental wear.
- Grounded plugs: Reduce the risk of electric shocks.
- Weatherproof jackets: Shield the cord from UV rays, water, and temperature changes.
Selecting the right gauge
Cord gauge determines how much power it can handle. Use the table below to choose the right one for your needs:
| Cord Gauge (AWG) | Suitable For | Maximum Length (ft) |
|---|---|---|
| 16 AWG | Light-duty (e.g., lights) | Up to 50 |
| 14 AWG | Medium-duty (e.g., power tools) | Up to 100 |
| 12 AWG | Heavy-duty (e.g., heaters) | Up to 150 |
Avoiding common mistakes
- Never use indoor cords outside, even temporarily.
- Avoid using cords with exposed wires or damaged insulation.
- Check for certifications like UL or ETL to ensure quality.
Do outdoor extension cords need to be covered?
Covering cords can extend their lifespan and ensure safety in extreme weather.
Yes, outdoor extension cords should be covered to protect them from environmental damage and reduce safety risks.
Why cover outdoor cords?
Covering cords prevents:
- Moisture intrusion: Reduces the risk of short circuits and electric shock.
- UV degradation: Slows down wear caused by prolonged exposure to sunlight.
- Physical damage: Shields cords from accidental cuts or abrasions.
Effective ways to cover cords
- Cord protectors: These durable sleeves wrap around cords and provide an additional layer of insulation.
- Cable management boxes: Enclose connections and extra cord length inside a weatherproof housing.
- DIY solutions: Plastic containers with sealed lids can work as temporary housing for plugs.
Conclusion
Outdoor extension cords can be left outside if you choose the right type and take necessary precautions. Always use outdoor-rated cords, protect them from rain and direct sunlight, and inspect them regularly to ensure safety and longevity.
