In parallel installations, the dynamics of ground fault current and the sizing of equipment grounding conductors (EGCs) are critical considerations for electrical safety. This becomes particularly significant in the context of ground faults and their impact on the electrical system. …
This article explores the technical justification for sizing equipment grounding conductors (EGCs) larger than ungrounded conductors in electrical raceway installations. It emphasizes the role of impedance and the behavior of fault currents, noting that fault current, while primarily following the …
