Grounding is an interactive training module designed to familiarize trainees with both system grounding and equipment grounding. After com-pleting this module, the trainees should be able to describe different types of grounding, describe NEC requirements associated with system grounding, and describe how to size and install grounding electrode conductors. They should also be able to describe NEC requirements associated with equip-ment grounding, describe how to size equipment grounding conductors and bonding jumpers, and explain how to make sure that a grounding system is effective.
