This self-paced online course explains National Electrical Code requirements for grounding and bonding. These two processes - which are related and overlapping but not the same - are important parts of fulfilling the NEC's overall purpose of protecting of persons and property from hazards arising from the use electricity.
Upon completion you should be able to:
- Distinguish between grounding and bonding.
- Explain the significance of performance requirements and prescriptive rules.
- Identify the importance of an effective ground-fault current path.
- Define and explain the key elements of a grounding and bonding system.
- Identify how these elements are combined to create an effective system design.
- Identify some of the details of system grounding, bonding and equipment grounding.
- Identify why and how materials in addition to electrical equiment must be bonded.
Who Will Benefit
Anyone whose job involves designing, reviewing, evaluating or installing fire protection systems, including: designers, installers, engineers, electrical contractors, technicians, project managers, fire marshals, and architects.
- Once the key elements of the system are understood, the next step is to understand how the prescriptive requirements apply to each element and help to meet the performance requirements of the system.
- The sizing of conductors and equipment often differs depending on whether they are on the supply side or the load side of the system and what type of system is involved, that is, whether it is within a primary structure or a secondary building, whether it is a service, whether it is a separately derived system and so on.
- In addition to electrical equipment, other elements of a building must be bonded, including water piping, other metal piping, structural metal, other systems and inter-system bonding conductors.
