Electrical Ground Tester

The tester itself is a small device which looks like the plug in end of a power cord with several lights on it rather than an attached cord.

Electrical ground tester.

The ground tester calculates the loop resistance of the ground earth. These testers are designed to test ordinary electrical outlets but only grounded outlets that have three slots. Test the resistance of a single rod in a series or array. Simultaneously perform a bonding test of the grounding conductor necessary to complete the return path.

To ensure a reliable connection to earth the international electrical testing association specifies ground electrode testing every three years. Test any grounding electrode configuration where there is a return path that includes the earth.

Just because your outlet has three prongs doesn t mean it s properly grounded however. This test ensures that the ground on the circuit is connected to the outlet and that it is working. Earth ground testers it is critical for facilities to have grounded electrical systems so that in the event of a lightning strike or utility overvoltage current will find a safe path to earth. The first is the 3 point or fall of potential method and the second is the induced frequency test or clamp on method.

This method is in many ways similar to ground testing using the fall of potential test. An electrical tester plays a key role in safety on the job so be sure to add this to your kit. The 3 point test requires complete isolation from the power utility. Testing for ground can be performed using either a multitester or a basic voltage tester.

The ground wire connected to the circuit allows any built up electricity from a sudden surge to travel through the ground wire and into the earthing rod to dissipate. Two slot outlets are best tested with a neon circuit tester. Years of field research combined with extensive input from electricians across america inspired the development of meters and electrical testers loaded with innovative time saving features. Older two slot outlets cannot be tested with the testers because no ground wire is connected to these outlets.

If you are using a basic voltage tester then you do not need to do anything to the tester as testing for voltage is its only function. However if there is only one path available for the electricity to pass to ground stakeless testing won t work. If you are using a multitester set the tester to read voltage v.
