nothing like redundant grounding

why would one need to pound a rod next to two 3" chunks of conduit going underground? seems pretty redundant to me.

Does the conduit continue in metal form for a distance of 8' underground? I can't tell from here ;)

I wonder if they connected it to the rebar as well.

Besdies, as a practical matter, one ground rod is only code compliant if you meet the 25 Ohm requirement. But I rarely if ever see two rods.

Yeah but the way I interpret 250.52 (A)(5) is a conduit exclusively driven to be an electrode. Not a conduit used as a raceway.

It doesn't say that conduit has to be used exclusively as an electrode.
 
Sure but common sense tells me that having an electrode that contains service conductors or feeders wouldn't be a great thing during a lightning strike....:mad:

How would it be any worse during a lightning strike than if it was not being used as a GE? Its still underground!!! In the picture I took it is within a few inches of the ground rod.

Common sense tells you whether or not you call it an electrode it will work the same task, it is in the ground/earth, it is connected/bonded to the EGC which in turn is common to the neutral/grounded conductor and grounding electrode.

How would you keep lighting off this conduit?
 
Lightning like water, dust and kids goes where it wants too, when it wants too and while we can install devices and grounding systems to minimize the damage, mother nature can always throw something bigger and badder than we prepared for.
 
In Wi. we are required to pound two rods no matter what. Took away arguing about if things realy were 25 ohms or not, and other than our backs, you realy can't have too much ground.:smile:
