Installation and measurements of earth electrodes - Electrical Installation Guide

The interesting factor here, not specifically mentioned in the link, (although distances between the rods are mentioned), are the zones of influence between each of the installed earth rods and why there is an optimal distance. which would indicate the fall off potential so that there is no overlapping gradient between each of the electrodes
 
I would ensure your spacings are 2.2 times the length of the Rod, providing you have the space, this should ensure no overlapping.

It would serve no useful purpose spacing rods at these sort of spacings on a multi rod installation... 1.5X the driven rod depth is ample.
 
Well, that spacing has worked for thousands of years between the klingon and romulan empires, so it should be ok for the humble earth rods.
 
they are cheaper at the borg on line shop. they come ready integrated as a collective combination of rods.

One, it's not the depth, it's the length of the rod which determines the size of the hemisphere, two, the 2.2 is the correct spacing, at 1.5 there will be overlapping of the hemisphere's. Come on E54 get current lol
