proper material for service grounding rod?


I'm moving the service entrance for my well pump house. I have the permit and the inspector has approved my plans. I failed to ask him what the proper material is for the ground rod. The current one is steel....is that ok or do I need to get a copper (or other rod)? I'm taking no short cuts since I know how important a proper ground is.

Thanks,
Jim

Check 250.52 (5)

Rod and pipe electrodes.

Rod and pipe electrodes shall not be less than 2.5m (8ft) in length and shall consist of the following materials.

(a) Electrodes of pipe or conduit shall not be smaller than metric designator 21 (trade size 3/4) and, where of iron or steel, shall have the outer surface galvanized or otherwise metal-coated for corrosion protection.

(b) Electrodes of rods of iron or steel shall be at least 15.87 (5/8in) in diameter. Stainless steel rods less than 16mm (5/8in) in diameter, nonferrous rods, or their equivalent shall be listed and shall not be less than 13mm (1/2in) in diameter.


Id sink a copper clad rod.

Grounding electrode can be minimum 3/4" galvanized or metal coated pipe.
5/8" Stainless Steel, copper, or zinc coated rods.
All Elcetrodes can not be less than 8ft.
I'm with rgsgww, copper clad rods is the way to go.

Whatever they stock at your local Home Depot or supply house.

Here, everything is copper clad steel. Other places seem to use galvanized. Government projects that want to waste money may specify stainless steel.

Is this a service entrance, or a well pump feed? Or is it a dedicated service for just the pump house?

I picked up a copper clad rod at the local Lowes today. Tomorrow will be the adventure of driving it in. Fortunately, no rocks in the area, just clay and sand so I don't anticipate a big problem.

Speedy, this is for a service drop (meter, breakker panel, etc) which serves a small storage shed and water well - total of 50 amps. The well is the primary use.....the other circuits are for a couple receptacles and shop lights.

Thanks again,
Jim

Keep in mind, I don't know if your inspector will pick up on this, but the service must be rated at no less than 60A for this installation.

Speedy,
I explained it poorly. It has a 100 amp breaker box with only 50 amps worth of breakers in it. So I should be OK.
