Grounding Introduction To The Basic Fundamentals by Tom Henry

                                                Grounding Introduction

        The mystery of grounding has always been confusing to many. Grounding has always had its controversial aspects.
        It has been rumored that only three people have ever understood grounding, and they disagreed.
        I'm writing this book for the student preparing to become an electrician so the mystery of grounding will not follow them throughout their career as it has mine.       
        This book is written for an electrician to understand why we ground before we ever start explaining what the Code says.

   Grounding is an electrical circuit. The grounding circuit can be conductors or in some cases a conduit system is the grounding circuit. The mechanical connections of fittings, conduits, boxes, etc. are just as important as the electrical connection of the circuit wires. Each mechanical fitting is a part of the grounding circuit path and must be connected with just as much care as the electrical circuit conductors. Very few faults occur between wires in a conduit. The point of connection or termination is where most faults take place.
    It is not possible to use electricity without involving some risk. It is impossible to prevent dangerous voltages to ground on an electrical system unless we do away with electricity completely because we cannot prevent a fault condition from occurring. The job of the electrician is to hold that risk to a minimum by installing protection which will reduce the existence of voltages to ground on equipment to a minimum and hold the fault condition to a minimum time duration.
    We must understand what a circuit is. An electrical circuit is a path or route of least resistance in which electrons flow from the source of supply to accomplish the electrical work and flow through the circuit back to the source of supply.
    Sometimes too much emphasis is put on one's knowledge of Code rules and sizing of bonding jumpers, electrode conductors, etc. Before one can discuss proper sizing of grounding conductors, you must first understand the reasons for grounding a system, theory, Ohm's law and what takes place when a fault condition occurs in the system.
