Grounding wire of photovoltaic distribution box
26 mm 2 (10 AWG) ground wire must be used, and in all other markets a 6 mm 2 must be used. Grounding (also known as earthing) is the process of physically connecting the metallic and exposed parts of a device to the earth. It is a mandatory practice required by NEC and IEC codes to protect both equipment and personnel from damage and electric shock hazards. Surge protection devices (SPDs) installed inside the distribution box help protect photovoltaic systems from transient voltage surges caused by lightning. 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. It connect every part of the PV racking be grounded through an integrated This PV grounding wire use high.
