I wanted to pass along to you a report written by James A. Montross, called Where is the Ground? He presents a case study where past and current code editions are in conflict with each other. I hope you find it has value.
 With each code cycle, the code evolves in response to events, practices, and developing technologies.
In the discussion herein, I present a case study where past and current code editions are in conflict with each other. Supporting the case study are discussions of code and history that help to shine a light on the potential problems between code editions.
What you will learn: some National Electric Code history, history of power generation, grounding fundamentals, and a solid approach to code review for modernizations of vintage buildings.
Special thanks to Mike Holt for his invaluable contribution to this paper.
