RE: as high as 25 ohms....


Many people read that part of the NEC code incorrectly.
NEC actually says if the ground resistance is greater than 25 ohms it shall be augmented by one additional electrode. (NEC 2008, 250.56)

The ground resistance could be 1000 ohms.... If the electrode was one 8ft ground rod then by code at least one more 8ft rod would be need to be driven. Code is satisfied....


Heheh. Clever.

Though Henry's point remains the same.
