Can electrical wire be buried underground?
As long as it’s got the right insulation, it’ll be just fine in the ground by itself. The most commonly referred to types of Direct Burial wire are USE (Underground Service Entrance) – with a thermoset insulation – Tracer Wire and UF, or “Underground Feeder” – both with thermoplastic insulations.
Do you need conduit for underground wire?
Underground Wiring Requirements – How Deep Do I Bury the Wire? Use direct-burial underground feeder cable at 24-inches deep (or more). You don’t need to use conduit at this depth with UF cable, however, you do need to provide PVC conduit on your vertical feeds starting at 18-inches.
How deep should electric lines be buried?
36 inches
Direct buried cables or cables in flexible nonmetallic enclosures shall be installed at a depth of at least 36 inches.
Does underground electrical have to be in conduit?
Low-voltage (no more than 30 volts) wiring must be buried at least 6 inches deep. Buried wiring runs that transition from underground to above ground must be protected in conduit from the required cover depth or 18 inches to its termination point above ground, or at least 8 feet above grade.
Can you bury an extension cord outside?
Extension cords are not rated for direct burial, and are not meant for long term exposure to the elements. They are meant for temporary use. If you are going to extend a circuit, do it right.

Can you bury electrical wire underground without conduit?
How to find buried electrical wires?
If you’re not familiar with how to use a metal detector, there are plenty of tutorials online. Another way to find buried electrical wire is to use a cable locator. This is a special tool that uses electromagnetic signals to find the wire. It’s more expensive than a metal detector, but it can be helpful if the wire is buried deep underground.
