Another bonding question

[grottoguy]

What ia the rational for why the bonding wire can only be 4-6 inches below grade and 18-24 inches from the water's edge. I have a Grotto (the immediate back of which is not accessible due to rocks) and I noticed that the bonding wire behind part of the Grotto is in some places probably 12 inches below grade and in some places about 27 inches behind the water's edge. I have tried to find an explnation of why these rules were chosen, and whether these apparently slight deviatioms are significant.

Thanks

There isn't much point in worrying about things like that. If you pass inspection, leave it alone.

I would think the 4-6 is so the bonding wire is close to the surface and the 18-24 is the center of the zone that people use to transition between water and deck and where they generally walk wet and barefoot.
