What is the intentional grounding of all metal noncurrent carrying parts of the electrical system called?

The intentional grounding of all metal noncurrent carrying parts of the electrical system is known as equipment grounding. This practice is crucial for safety, as it provides a path for fault currents to flow safely to the ground, thereby minimizing the risk of electric shock or fire. Equipment grounding helps ensure that any stray current that might come into contact with a metallic surface is directed away from individuals and other equipment, promoting safe operation and preventing damage to the electrical system.

Other terms like safety grounding and electrical grounding might be used interchangeably in some contexts, but equipment grounding specifically refers to the connection of noncurrent carrying metal parts to the grounding system of a facility to enhance protection against electrical faults. Chassis grounding, while related and often concerned with grounding in the context of enclosures for electronic equipment, does not encompass the full range of noncurrent carrying parts as equipment grounding does.
