NEC GROUNDING

NEC GROUNDING & BONDING

The focus of this course is to ensure personnel and property electrical safety protection and the proper grounding of electrical services, raceway systems, and equipment as regulated by the National Electrical Code. The student will under go a basic review of electricity, circuits, loads, Ohm's Law, and the characteristics of electron flow. This course also covers grounded systems and symbols, fault current, NEC grounding requirements, voltage potentials, grounding methods, grounding electrodes, and grounding electrode conductors as well as grounding and bonding by focusing on bonding, equipment grounding and equipment grounding conductors. Upon completion the student should be able to define bonding and describe the methods of bonding, discuss NEC requirements regarding equipment grounding as well as be able to select size equipment grounding conductors according to NEC requirements and recognize the different methods of equipment grounding.
