Jayson - this topic is FAR too complex for anyone to give you an 'in-a-nutshell' explanation on this topic. There are many of us who have studied this subject for years and are still learning everyday. I strongly recommend you buy Mike Holt's "Grounding & Bonding" book on this subject - it is color illustrated, takes you through Art. 250 and is as clearly written as possible for this subject. I think most people come away feeling it is a very understandable and 'user-friendly' text on the subject....$30
