Nec Service Ground Wire Diagram. 2017 nec study guide for grounding electrode systems this study guide was prepared by gaylord poe few things are more frustrating for an electrician than trying to figure out how the nec rules for service grounding and bonding are going to be interpreted and enforced by the local electrical inspector. The current path shown between the supply source ground ing electrode and the grounding electrode at the service main shows that some current will flow through the earth but the earth is not part of the effective ground fault current path.
Ground wires for residences typically are made of copper and are 6 6 awg or larger. The current path shown between the supply source ground ing electrode and the grounding electrode at the service main shows that some current will flow through the earth but the earth is not part of the effective ground fault current path. The main components of this effective ground fault current path are made up of the equipment grounding conductors such as bonding jumpers main system supply side equipment and service or system grounded conductors.
The 2008 national electrical code and the nec 2008 handbook respectively.
They only provide general information and cannot be used to repair or examine a circuit. As a continued service to the industry we are making this available at no charge. Nec service ground wire diagram show the circuit flow with its impression rather than a genuine representation. 514 applies to the fuel dispensing areas.
