Cross-sectional area of ​​grounding wire in optical cable junction box

The cross-sectional area of the grounding wire is more than 6mm², and there is an obvious grounding mark at the grounding point. Some structures and characteristics of typical representative OPGW are shown in the below list, however, they do not represent the whole products of the company. This AE Note does not address outside plant fiber optic installations or. The main principles followed by. Earthing Cable Size as Per IEC is determined primarily by the requirements of IEC 60364-5-54. The standard provides two accepted methods for selecting a conductor size. Engineers can calculate the required cross-sectional area using the adiabatic equation or select a conductor based on the minimum. This calculator determines the minimum required cross-sectional area for protective earthing (grounding) conductors based on fault current, fault duration, and conductor material properties.
