This two hour online course examines the methods used to provide grounding protection for both people and equipment. The purpose of protection grounding, National Electrical Code® requirements, and the various factors that affect electrical grounding are discussed. Design calculations are presented for single rod grounding systems, linear grounding systems, and rectangular grid grounding systems.

After completing this course, the student will know how to design a simple grounding system, how to measure the effectiveness of the grounding system, and how to improve the effectiveness of a grounding system.

This course includes a multiple choice quiz at the end.

• Understand the factors that influence an effective grounding system.


• Understand the code requirements for protection grounding.


• Know how to design simple grounding systems.


• Know how to measure ground resistance and soil resistivity.
