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.
NEC 2023 Basics: Equipment Grounding Conductors
2023年8月2日 · Learn about equipment grounding and types of equipment grounding conductors. Part VI of NEC’s Article 250 states the rules for equipment grounding and equipment grounding conductors. This part of the NEC lists the equipment grounding conductors’ permitted and not permitted types.
Equipment Grounding Conductors, based on the 2020 NEC - Mike Holt
Know the types of equipment grounding conductors, and how equipment grounding conductors must be identified. The equipment grounding conductor (EGC) serves as part of the effective ground-fault current path [Article 100].
NEC 2023 Basics: Equipment Grounding Conductor Continuity …
2023年9月10日 · An equipment grounding conductor contained in a cable assembly or flexible cord involving the power supply conductors and terminated in a grounding-type attachment plug with one fixed grounding contact.
NEC 2023 Basics: Identifying Wire-Type Equipment Grounding Conductors
2023年8月29日 · Wire-type equipment grounding conductors may be bare, covered, or insulated unless required to be insulated elsewhere in the NEC. Individually covered or insulated conductors must have an uninterrupted surface colored green or green with one or more yellow stripes, with three exceptions.
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.
Understanding NEC 250.122: A Practical Guide to Equipment Grounding ...
2024年11月5日 · This comprehensive guide delves into the intricacies of NEC 250.122, a critical section of the National Electrical Code (NEC) that governs the sizing of equipment grounding conductors (EGCs). Understanding and applying these guidelines is paramount for ensuring the safety and reliability of electrical systems.
NEC 250.122: Equipment Grounding Conductor Sizing
NEC 250.122 specifies the minimum size of the equipment grounding conductor required for a circuit. The size of the grounding conductor is based on the rating of the overcurrent protection device (such as a circuit breaker) that is used to protect the circuit.
