Behind the Equipment Grounding Conductor - EC&M
2000年7月1日 · You use an equipment-grounding conductor (EGC) to ground the noncurrent-carrying metal parts of equipment. Its function is to keep your equipment as close as possible to ground potential and provide a safe path for ground-fault current to flow.

2021年3月2日 · But let’s first look at what constitutes an equipment grounding conductor (EGC) and how it differs from the oft-misunderstood grounding electrode conductor (GEC) that connects noncurrent-carrying metal parts of the electrical service to the electrode buried in the earth. EGCs VS. GECs. Equipment Grounding Conductor (EGC): Table 250.122
Equipment Grounding Conductors. - ElectricalLicenseRenewal.com
An equipment grounding conductor (EGC) connects the non-current carrying metal parts of equipment and metal enclosures to the grounded conductor at the service (which is connected to earth) and provides a low impedance path (an Effective Ground-Fault Current Path) to carry fault current in the event of a fault to ground occurring in an ...
Installing and Sizing Equipment Grounding Conductors - Mike Holt
An equipment grounding conductor (EGC) is actually an equipment bonding conductor. It forms a metallic path not to the earth (grounding, as defined in Article 100) but back to the source. Recall that where a wire EGC is required, it's run with the phase conductors instead of to a ground rod.
250.121 Use of Equipment Grounding Conductors.
Equipment grounding conductors (EGC’s) serve to provide a ground-fault current path by connecting normally non-current carrying metal enclosures of electrical equipment to the system grounded conductor or the grounding electrode conductor or both (see Article 100 definition of Grounding Conductor, Equipment).
