That is ForTran, not FORTRAN. Formula Translator ;) ;)

What would work if you bury it deep enough. I would believe 8 feet of
strap
buried 4 feet down should be equal to an 8 foot rod pushed down 8 feet.
I do think it is less work to push the rod down than to dig a trench for
the
strap.

What if one were not to use a ground rod and just bury the strap?
The code allows you to drive the rod at an angle.
From an electrical standpoint, you don't need to bury the strap 8 feet
down.
IEEE 142-1999 Table 13 has formulas for all kinds of configurations of
rods, wires, straps and the like. there's a new version from 2007 out.
If I get ambitious, I'll put some of the equations online, but they're
long series expansions, so a bit tedious.
Anybody have a preference.. as matlab/octave/fortran/c equations or as
Excel Spreadsheet formulas?
