Find Ground Faults in A Pinch


RIDGID A-Frame Fault Locator makes finding faults in buried conductors a lot easier for operators. They are designed for incredible accuracy and operator safety since it utilizes low voltage to find the exact position of ground faults in direct buried insulated wire up to two megohms. Consisting of both a transmitter and receiver, the locator streamlines the fault location process to isolate problem areas in minutes.

Ideal for use in electrical service, telecom, cable, railway, irrigation and ‘invisible fence’ applications, the A-Frame Fault Locator can find faults up to three miles away from the transmitter and up to 20 ft. below the ground, depending on conditions. It has a durable, lightweight, powder-coated frame; weatherproof membrane buttons; provides a reference readout to aid in fault location.


The A-Frame Fault Locator’s functionality compliments other RIDGID locators, including the SeekTech SR-20, SR-24, and SR-60 Underground Utility Locators.


The A-Frame Fault Locator comes with the A-Frame receiver, transmitter, ground stake, test leads, batteries and carrying case.
