ABSTRACT
System grounding is connecting a current-carrying conductor to ground potential at one place in a system. Traditionally system grounding is done by connecting a conductor directly to earth. The grounded conductor is generally colored white for grounded systems. There are many factors to deal with here and grounding electrode systems outside of photovoltaic (PV) are also hard to understand and are implemented differently regionally. A grounding electrode system includes pieces of metal connected to earth and other pieces of metal connecting those pieces of metal together and then to the grounding system via a grounding electrode conductor. PV array equipment grounding conductors shall be connected to the grounding electrode system of the building or structure that is supporting the PV array. Additional Auxiliary Electrodes for Array Grounding said that these electrodes shall be installed and got a few people irate.
