Select a Locator

First, you need to find the right type of locator. Magnetic locators allow you to find the approximate depth and location of buried ferrous metal objects. This includes septic tanks, corner pins and other objects. Unfortunately, it does not include electrical wires. Most buried wires are made of copper. Other elements may include aluminum or gold, but none of these are ferrous. For buried electrical cables, it’s best to use a pipe and cable locator.

Advantages of Using Pipe and Cable Locators

Pipe and cable locators offer an effective way to locate buried electrical lines and conduit. They operate slightly differently than magnetic location devices, allowing them to find a signal from a non-ferrous metal. Some utilities have a signal running through them. Power lines give off a 60Hz frequency, which your pipe and cable locator can detect. For other pipes and cables, a transmitter is needed. Connect the transmitter to an exposed piece of pipe or cable to safely transmit a signal through. Your location device will receive the signal, allowing you to find a buried section of the same cable or pipe. There are many different types of transmitters. Compare alligator clamps, signal clamps and inductive antennas to find the best option for your specific cable location project.

Frequently Asked Questions

Will a Locator Find a Buried Electrical Wire?

Blog will a magnetic locator find a buried electrical wire

No, a Schonstedt magnetic locator isn’t capable of locating buried non-ferrous items. A pipe and cable locator is required to find any materials that aren’t magnetic. It may be possible to locate a cable if it’s buried in steel conduit, but typically you must use a transmitter and cable locator.

Can a Magnetic Location Device Find Buried Water Lines?

Water lines can be copper, PVC or other plastic, but they aren’t usually ferrous metals. For this reason, your magnetic location device isn’t suited for finding water lines. You may need to use a pipe and cable locator or other utility locator tool to find these buried lines.

How Can You Locate Underground Fiber Optic Cables?

Fiber optics aren’t ferrous, so you won’t be able to use a magnetic location device to find them. A utility location device that uses a transmitter can send a signal down the line and trace it with a handheld receiver. For this to work, you’ll need to find an exposed section of the fiber optic cable to connect a transmitter to.

How Do You Use a Locator?

A magnetic location device can detect ferrous materials by slowly moving the handheld locator back and forth over the area. Pipe and cable locators operate in a similar way, but typically need a transmitter to send a signal through the cable you’re locating. Follow the specific instructions for your location device for accurate use.

What Types of Utility Locators Are Available?

Visit Engineer Supply to find a utility or magnetic locator device for your next project. Shop for locators designed to search for buried electrical lines to prevent accidental damage and risk of electrical shock as you safely dig new trenches or a foundation.
