Have you noticed that the horizon is dotted with fewer power poles than it used to be? Since we know our country has not reduced its use of power, how is this possible? The answer is underground power lines. Today, the technology exists for an underground utility contractor in Roseville, CA to bury lines beneath the surface.

If you need to run power for a project at your home, you can apply similar methods. Depending on your location and needs, you have several options. First, you must decide how much digging you need (or want) to do. This will determine the type of wire required. No matter what you decide, all options require the same preparatory steps.

The prep work

  • Inspection: Consult with an inspector before beginning your project. Ask about any safety concerns for your location. Ensure you have all the information you need before digging in. If needed, contact an underground utility contractor in Roseville, CA to ensure the job is done properly.


  • Permit: Obtain any permits required for your underground power line installation. These may come from the city, county, homeowners association or other local regulatory offices. Taking the time to obtain the right permits can save you headaches and fees down the line.


  • Service entrance ell: The depth and materials you choose will vary, but always include a service entrance ell. This has a removable cover that will provide access to the wires above ground level.

The options

  • 6 inches: If you don’t need to dig very far, or have soil that’s tough to dig, this method is a good choice to cut down on the digging. At this depth, use galvanized metal ridge electrical conduit. Run individual conductors inside. Be sure to choose waterproof conductors. With this method, you can run any size circuit.


  • 12 inches: At this depth, use direct-bury UF-B cable. Be sure the cable has GFCI protection before it enters the ground, is protected by no more than a 20-amp fuse or breaker and is limited to 120 volts. With this option, you will have to dig deeper, but you won’t have to use expensive conduit.


  • 18 inches: If you need to run electricity to several items, this is a good option. It allows you to run any size circuit. Use THWN-2 conductors inside PVC conduit at 18 inches below ground.


  • 24 inches: Only use this method if you will be digging in easy-to-remove soil or are using a trench digger. To run underground power lines 24 inches below the surface, use direct-bury UF-B cable. Keep in mind this requires a conduit that is exposed on the outside of the house.
