Burying an extension cord may seem like a simple solution to your outdoor power needs, but it’s not as straightforward as you might think. Safety should always be your top priority, and it’s crucial to understand that not all extension cords are suitable for burial. In fact, extension cords aren’t rated for direct burial at all, making them potentially dangerous and ineffective when used in this way.
If you’re considering this, you need to think about whether this is a temporary or permanent solution. The National Electrical Code (NEC) only permits burying extension cords for a temporary period. If you’re thinking long term, it’s time to consider wiring your house instead.
The depth at which you bury the cord is another important consideration. Anything below 18 inches is illegal, so be prepared to dig a little deeper. And remember, always consider using a conduit before burying an extension cord. It provides that extra layer of protection your cable needs.
The Importance of Properly Burying Extension Cords
Safety first! Regardless of the project you’re undertaking, safety should always be your top priority. The same goes for burying an extension cord. It’s vital to remember that extension cords aren’t designed for direct burial, and if they’re not properly insulated and shielded, they can become a significant safety hazard.
When extension cords are buried without protection, moisture, dirt and insects can seep into the cord, leading to electrical shorts and potential shock hazards. The risk is even greater if the cord is damaged or cut.
Here’s a few things to remember to ensure you’re burying your extension cords safely:
Use a conduit: A plastic or metal conduit can protect your cord from damage, moisture and pests. It also makes it easier to replace the cord if necessary.
Bury at the right depth: The National Electrical Code requires that outdoor electrical wiring be buried at least 18 inches deep. This reduces the risk of someone accidentally digging into the cord.
Use the right cord: Not all extension cords are created equal. Always choose a cord that’s suitable for outdoor use, and check that it’s rated for the wattage of the appliances you’ll be using.
Remember, burying an extension cord is only a temporary solution. If you need a long-term outdoor power solution, consider having an electrician install a permanent outdoor electrical outlet. This will provide you with a safer, more reliable power source for your outdoor power needs.
