Understanding Grounding
Grounding refers to the process of connecting a conductor or exposed conductive parts of an electrical installation to the earth. This connection ensures safety by preventing electrical shock and stabilizing voltage levels in electrical systems, protecting both equipment and personnel from stray currents.
Understanding Bounding
Bounding describes the act of establishing limits or boundaries around an area or concept. It serves to define the scope of an object, idea, or space, ensuring clarity and focus within specified parameters. Bounding can be applied in various contexts, including mathematics, geography, and data management
Why Grounding and Bonding Matter for Cable Trays
