  • Cable locating devices.
  • Safe digging practices.

How do you find buried electrical wires?

Use an underground cable locator to find buried cable. When first introduced approximately 40 years ago, underground locators needed to do little more than find buried water, gas, or sewer lines. Today, locating has become more complex as telecommunications cables join utility lines in the underground environment.

Maximum Depth
In theory, it is possible to dig several stories deep under your yard and even spread out to move across your yard and into others.
