Figure : Radial ground
Figures  and  represent examples of
recommended stand alone grounding
systems, or minimum grounding system
requirements for each ERICORE down-
conductor. It is required to have minimum
of two down conductors, when conventional
conductors are used. Figure  represents the
Figure : Grid ground
minimum grounding system requirement or
each conventional downconductor.
Where other grounding systems are present,
a minimum of one copper-bonded ground
rod (/ in diameter x  ft length) bonded to
the existing system is required.
