From Article through Chapter 2 provides the general rules for wiring and protection of conductors. As you go through Chapter 2, remember the purpose of it. Chapter 2 is primarily concerned with correct installation of circuits and the means of protecting them. Every Article in the Chapter deals with a different aspect of fulfilling that purpose.
Grounding has often puzzled experts and caused non-experts to quake through the years. In the late s, because there was so much confusion on this topic, the NEC Correlating Committee formed a special task group for usability to tackle Article The charter for this task group was to make the requirements more logical and to add clarity to this subject. That process has been ongoing with each successive Code cycle. In this 13th edition of Soares text, through the use of examples and detailed illustrations, IAEI has again tried to set forth clearly the theory and practice of grounding and bonding, allowing you to have tools to better master the subject. Seldom do design, engineering, installation and enforcement perspectives come together in one book, especially on the controversial topics of grounding and bonding.

The overcurrent protection shall be permitted to be provided by either Cir-cuit breakers used for overcurrent protection of 3-phase circuits shall have a minimum of three overcurre nt relay elements operated from three current transformers. The sepa-rate overcurrent relay elements or protective functions shall be permitted to be part of a single electronic protective relay unit. On 3-phase, 3-wire circuits, an overcurrent relay element in the residual circuit of the current transformers shall be permitted to replace one of the phase relay elements. An overcurrent relay element, operated from a current transformer that links all phases of a 3-phase, 3-wire circuit, shall be permitted to replace the residual relay element and one of the phase-conductor current transformers.
