Need to determine quality of ground connections
Need to determine quality of ground connections
(OP)
Hi there. I need to determine the quality of the ground connections within a building. What kind of device should I use to determine this, and where can I get one?

(BTW, Just how are things in Dogpatch these days?)

As for Dogpatch... If Ah had my druthers, Ah'd move somewhere else.

Even though you measure a low resistance to ground using a traditional ground tester, this does not necessarily tell you how the system will handle 30,000 amperes of current.
The resistance of the *connections* is best tested using a low-resistance Ohmmeter ("Ducter"). This will give you some indication of how well the grounding system will handle high fault currents.
