For the practitioner and the student-practical guidance in a single volume.
This compact all-in-one resource tells how to apply NEC rules in the most efficient manner in varied settings, with the regulations applying to a particular type of installation together in one place. Design pointers on how to make installations convenient and neat are another example of the "practical" aspect of the book. Job planning, techniques, and wiring calculations are explained in a detailed yet easy-to-understand style. Hartwell gives hints, cautions, and handy tricks used by veteran practitioners and offers rarely available information from an insider's perspective. For many topics you get not just today's rules, but a look back at how those rules came about over the years-useful in identifying and working on wiring systems of any age.
