Abstract:
A fall of potential method of determining earth ground resistance which utilizes an earth ground tester and eliminates the need for utilizing removable ground stakes. Rather than utilizing a “far stake” the method provides connection of the earth ground tester to the telephone wires. Rather than utilizing a “near stake” the method provides for connection of the earth ground tester to the cable shield.
