2025年1月25日 · EGC and GEC meet at the main service panel (or separately derived system) where they both typically connect to the grounded conductor (i.e. the neutral, almost always).

2012年3月20日 · The GEC- is used to bond the grounding electrode system together. Thus the water pipes, steel, ground rods, etc get connected to the GEC. The egc is the wire in cable or …

2010年8月12日 · I think an egc is the wire from neutral to cabinet or enclosure and gec is the wire from panel to ground rod or tranx to water pipe. Why do I keep getting these mixed up? Is …

2008年2月4日 · What’s the difference? I have a copper 4AWG wire connected to the bonding jumper (green screw) inside a 200-amp panelboard. The wire is connected to a grounding rod …

2011年10月27日 · Grounding Conductor, Equipment (EGC). The conductive path(s) installed to connect normally non–current-carrying metal parts of equipment together and to the system …

According to the NEC they would both require a GEC. They also will have a ECG which is built into the wiring harness. Depending on your AHJ the GEC can connect to the rails only and the …

2006年7月14日 · Just like a transformer you have to bond to the building which is actually an grounding electrode conductor (GEC) and still run a equipment grounding conductor (EGC). …

2024年11月25日 · In AC systems, grounding and bonding are usually combined in a single system, called the equipment grounding conductor (EGC). The EGC connects the metal parts …

2007年8月4日 · If there is overcurrent protection ahead of the circuit it is an EGC and sized per all the requirements in 250.122. If there is no overcurrent protection ahead of the circuit it is a …

2020年3月10日 · Depends on where you are. A EGC is required in the U.S. a GEC is allowed, but not required or recommended.
