In an ideal grounding system, there should be only one path to the earth for fault current to flow during faults, while every metallic part of the electrical system should be properly bonded together. When multiple ground rods are used, there is a risk of creating grounding loops, which can cause. Grounding and bonding are two distinct safety requirements for solar photovoltaic systems. Grounding connects electrical components to Earth at zero voltage potential. Most solar. This process involves two distinct but related concepts: system grounding, which provides a reference to earth for the electrical system (stabilizing voltages and assisting in clearing certain faults), and equipment grounding, which bonds all normally non-current-carrying metallic parts to provide. This is true for a solidly grounded system. 2) Connection of grounding and bonding of the equipment grounding conductor (EGC), grounding electrode conductor (GEC), and bonding jumpers at any point or mounting PV modules should be carried out through listed devices or systems (i. This is true for a solidly grounded system.
