They want to see ground rods. They look at houses every day and the
inspector told me he had never looked at a tower before - ever. Plus the
tower base is poured 6 weeks ago. So I need to put in a couple of ground
rods and just need to know what the typical house install rod height is.

What does the NEC code (meaning a safety ground and not the more expansive

I need to get the rural county building inspectors out to look at my
towers and want to show them something that they will have seen before
with respect to a basic safety ground. From what I understand locally
that means a pair of ground rods in a configuration like what would be
required at a house for the mains entry.
Today, that means a Ufer ground - 20 ft of conductor embedded in the
concrete. Conductor can be rebar.
To that end I am unsure what the height of the ground rod should be in the
NEC context? Is the connection wire/rod joint to be made above grade,
even with grade or below grade?
