Everyone uses extension cords these days. They can’t help it. Consumers have too many appliances and not enough outlets. Indoor extension cords are simple. They rarely attract confusion. Outdoor extension cords are different because they are more likely to get in the way, and people cannot help but wonder whether they can bury these devices.
Can You Bury An Extension Cord?
You can’t bury an extension cord because the cable cannot withstand the pressure, let alone elements like water. Pests are more likely to chew through the sheath, exposing the conductors to destructive elements like moisture. Once that happens, you will lose your cord. But that is not the worst-case scenario.

An underground extension cord is more likely to overheat. Any licensed contractor you consult will warn you about the dangers of covering these devices with rugs and carpets.
You don’t want to limit their ventilation because doing so allows the heat they generate to accumulate. Many extension cords start fires because someone covered the line with objects.
A buried extension cord is unlikely to start a fire. However, overheating can destroy the device. Unless you’re willing to replace your extension cord every few weeks, you are better off buying direct burial UF cables.
They can survive underground for long periods without overheating or deteriorating. Use direct burial UF cables to install permanent power sources next to the outdoor applications you want to operate.

Manufacturers do not make extension cords for consumers to bury. The strongest extension cords can resist water and UV rays. However, they were not designed with direct burial in mind.
You can try searching for a UF-B extension cord but don’t expect to find it. If you want to bury cables, stick with electrical wiring. Run a UF-B line to the location with the outdoor appliance and install an electrical box at the end. This allows you to operate the machine without using an extension cord.

When Do I Need To Bury An Extension Cord?
You never need to bury an extension cord. Extension cords are not rated for direct burial.
If you’re tempted to bury your extension cord, it is probably because you want to hide it. Extension cords are helpful because they extend an outlet’s reach. However, they tend to stand out, which is why some people bury them.
They want to keep the cord out of sight. But if that reason sounds trivial. Extension cords are tripping hazards, especially outside, where people are less likely to notice them.
Hiding an extension cord in grass sounds reasonable until you realize that people are more likely to trip over it. This makes burial sound like an attractive solution.
But again, the dangers associated with burial are not worth the few benefits this practice brings to the table.
I can suggest you cover outdoor extension cords with tape. This reduces the chances of tripping while also camouflaging the cable.
A cheaper, more convenient option involves running the cord behind walls to keep it out of view. You can also use plants. Ultimately, burial is not the only solution at your disposal, despite what some people claim.
Pros & Cons Of Burying Extension Cord
Pros
- Prevents Tripping
- The cord won’t get tangled
- Burial protects the cord from threats like animals and extreme weather
Cons
- Pests will eat through the sheath
- The extension cord will overheat
- You may cut the cord while digging
- It can’t withstand the pressure
- Moisture is more likely to infiltrate the cord
Even If It Is Dangerous, How Do I Bury An Extension Cord?
- Make a plan. Identify the route the extension cord will follow. Avoid locations with electrical, water, and gas lines. Otherwise, you run the risk of accidentally cutting an electrical wire. Ask the contractor that installed those lines to guide you. More than likely, you have no idea where the lines are.
- Select a suitable extension cord. Prioritize the heaviest gauges you can find.
- Pull the extension cord through a conduit. The conduit provides an additional layer of protection. Select a pipe that fits your purposes. Some people prefer metal. Others gravitate towards plastic.
- Dig a trench. Follow the route you planned. The depth will depend on your local code’s regulations. This assumes that your local code permits this practice. If they don’t want consumers to bury their extension cords, they won’t say anything about the appropriate depth.
- Install the conduit and pull the cable through.
- Cover the conduit.
You can use these steps to install proper electrical wiring with a GFCI outlet at the end. If you have the time and resources to bury an extension cord, you might as well acquire a UF cable and bury it. This provides a long-term wiring solution.
