2017 NEC® Grounding and Bonding Workshop


This class on grounding and bonding provides review of one of the most important and often misunderstood article in the National Electrical Code®. The class provides attendees with personal instruction into the requirements surrounding the grounding and bonding of electrical systems and how it is addressed in the NEC®. This course provides excellent detail in the most relevant and frequently used applications covering grounding and bonding requirements. Workshop materials ensure the student has the necessary material for notes and information that he or she can take with them for future reference. This course is suited for contractors, electricians, electrical design professionals, inspectors to explain the intricacies about grounding and bonding for electrical systems.


Workshop Topics

  • Introduction to Grounding and Bonding
  • Coverage of the three tables in Article 250 dealing with grounding electrode conductor sizing, equipment grounding conductor sizing, and grounded, main bonding jumper, and supply side bonding jumper sizing
  • Review of grounding electrode systems
  • Four reasons for grounding systems
  • High frequency and harmonic grounding and bonding systems
  • Installation of grounding and bonding systems for utility supplied power systems
