Explain the difference between 'equipment grounding' and 'system grounding'.

Equipment grounding and system grounding are two distinct but related concepts in electrical safety, each serving a different purpose. Equipment grounding, also called protective grounding, is the practice of connecting the non-current-carrying metal parts of electrical equipment, such as enclosures, frames, and motor housings, to ground. The purpose of equipment grounding is to provide a low-impedance path for fault current to flow back....
