Can You Bury an Extension Cord?

Paul West/ Backyard Construction

You may wonder if an extension cord can be buried underground for convenience or functionality. It seems straightforward: place the cord beneath the surface to keep it protected and out of sight. But, before proceeding, it’s crucial to understand the risks and regulations of this approach. In this text, we will investigate into the nature of extension cords, address whether they are suitable for underground use, and explore the regulations and safe alternatives available.

Understanding Extension Cords

Key Characteristics of Extension Cords

Extension cords are versatile tools designed to provide temporary power delivery over a distance. Comprised of insulated wires encased in a flexible sheath, they come in various lengths and gauges to accommodate different electrical load requirements.

Intended Uses for Extension Cords

Typically, extension cords are designed for above-ground, temporary use. They allow for flexibility in powering devices in areas lacking accessible outlets. But, their construction is not tailored to the challenges of subterranean environments.

Risks of Burying Extension Cords

Electrical Safety Concerns

Burying an extension cord underground poses significant safety hazards. The insulation may degrade under pressure and moisture, potentially leading to short circuits and fire risks.

Durability in Subterranean Environments

Extension cords lack the robust construction necessary to withstand underground conditions such as pressure, moisture, and possible interference from plant growth or animal activity.

Legal and Code Compliance

NEC Regulations and Local Requirements

The National Electric Code (NEC) specifies types of wiring approved for underground installation, favoring conduit-protected or direct burial-rated cables instead of standard extension cords.

Permits and Inspections

Adhering to regulations often involves securing permits and conducting inspections to ensure installations comply with safety standards and local codes.

Appropriate Alternatives to Burying Extension Cords

Proper Methods for Underground Wiring

For a safe underground power distribution, opt for conduit-protected electrical cable installations or direct burial cables.

Selecting the Right Materials for Safety

Choosing materials rated for underground use ensures their durability, safety, and compliance with applicable regulations.
