2020 Understanding the National Electrical Code, Vol. 1 textbook
Compliance with the National Electrical Code is a major concern for today’s engineers, designers and electricians. On the one hand, you need to keep job costs down. On the other hand, your electrical projects must meet Code. And if you are an electrical inspector, you’ve got to ensure compliance with the Code in a way that is fair, accurate, equitable, and consistent.
The need to understand and accurately apply the NEC is paramount. How can you make sure you get this right? The answer is Mike Holt’s Illustrated Guide to Understanding the National Electrical Code. No other textbook takes you step-by-step through NEC articles like Mike’s authoritative Understanding the National Electrical Code textbooks. What makes this book so effective is the clear writing style, the Author’s Comments, the amazing detailed full-color illustrations that help you visualize the concepts being discussed, and the examples that are broken down step-by-step. The chapter questions help you test your knowledge as you go. This book sets the standard in NEC education and is used extensively throughout the country. Volume 1 highlights:
- Article 90. Know the purpose and scope of the NEC, and understand how it’s arranged so you can quickly find what you need.
- Chapter 1. Become familiar with the general requirements that apply to all installations. You’ll understand NEC terminology, which wiring methods are suitable, and the truth about space requirements.
- Chapter 2. Know the requirements for neutrals, branch circuits, feeders, outside wiring, and services. You’ll obtain competence and confidence in sizing and applying circuit protection. You’ll also understand how grounding and bonding differ, and how to apply the concepts properly in the real world.
- Chapter 3. The requirements for conductors, enclosures, fittings, cable assemblies and raceways are many, and the rules for wiring methods may vary with each type. Do you know how the rules for EMT differ from those for RMC? What about armored cable? Which conductor is right for the job?
- Chapter 4. Cords, switches, receptacles, panelboards, and lighting are just some of the topics in Chapter 4 you must understand to avoid Code violations. Don’t let Article 430—the largest of the NEC Articles—be a “motor mystery” to you. And the rules for generators, transformers, and capacitors are clarified so they'll not continue to confuse you.
This resource has proven itself in the field and in the exam room. And now you can rely on the latest edition to provide you with the rock-solid foundation of NEC knowledge necessary to do your job with accuracy and confidence.
2020 - Kuelewa Mfumo wa Kitaifa wa Umeme, Vol. 1 kitabu cha masomo Utii kwa National Electrical Code ni wasiwasi mkubwa kwa ajili ya wahandisi wa leo, wabunifu na wa umeme. Kwa upande mmoja, unahitaji kupunguza gharama za kazi. Kwa upande mwingine, miradi yako ya umeme lazima ipatane na Kanuni. Na kama wewe ni inspekta wa umeme, una kuhakikisha kufuata kanuni kwa njia ambayo ni haki, sahihi, usawa, na thabiti. Ni muhimu kuelewa na kutumia NEC kwa usahihi. Unawezaje kuwa na uhakika kwamba umefanya hivyo kwa usahihi? Jibu ni Kitabu cha Mike Holt kinachoitwa Illustrated Guide to Understanding the National Electrical Code. Hakuna kitabu kingine cha masomo kinachokuongoza hatua kwa hatua kupitia makala za NEC kama vitabu vya Mike vya kuelewa kanuni ya kitaifa ya umeme. Kitabu hiki kinafaa sana kwa sababu ya jinsi kilichoandikwa kwa uwazi, maelezo ya mwandishi, picha zenye rangi nyingi zinazokusaidia kuona mambo yanayozungumziwa, na mifano iliyofafanuliwa hatua kwa hatua. Maswali ya sura hukusaidia kupima ujuzi wako unapoendelea. Kitabu hiki huweka kiwango katika elimu ya NEC na hutumiwa sana nchini kote. Sehemu ya kwanza ya makala hii inaonyesha: Kujua kusudi na wigo wa NEC, na kuelewa jinsi ni kupangwa hivyo unaweza haraka kupata nini unahitaji. - Sura ya kwanza. Kupata ukoo na mahitaji ya jumla ambayo yanatumika kwa mitambo yote. Utaelewa NEC terminology, ambayo mbinu wiring ni sahihi, na ukweli kuhusu mahitaji ya nafasi. - Sura ya pili. Kujua mahitaji ya neutral, matawi mizunguko, feeder, nje wiring, na huduma. Utapata uwezo na ujasiri katika ukubwa na kutumia ulinzi mzunguko. Wewe pia kuelewa jinsi grounding na bonding tofauti, na jinsi ya kutumia dhana kwa usahihi katika ulimwengu halisi. - Sura ya tatu. Mahitaji ya conductors, enclosures, fittings, cable makundi na raceways ni wengi, na sheria kwa ajili ya mbinu wiring inaweza kutofautiana na kila aina. Je, unajua jinsi sheria za EMT zinatofautiana na zile za RMC? Namna gani kuhusu kebo yenye silaha? Ni kondakta gani anayefaa kwa kazi hiyo? - Sura ya nne. Vifaa vya kuunganisha, kuunganisha, kuunganisha, kuunganisha, kuunganisha, kuunganisha, kuunganisha, kuunganisha, kuunganisha, kuunganisha, kuunganisha, kuunganisha, kuunganisha, kuunganisha, kuunganisha, kuunganisha, kuunganisha, kuunganisha, kuunganisha, kuunganisha, kuunganisha, kuunganisha, kuunganisha, kuunganisha. Usiruhusu kifungu cha 430 - kikubwa zaidi cha vifungu vya NEC - kuwa "haijulikani" kwa wewe. Na sheria kwa ajili ya jenereta, transformers, na capacitors ni kufafanuliwa hivyo wao si kuendelea kuchanganyikiwa wewe. Rasilimali hii imejithibitisha yenyewe katika uwanja na katika chumba cha mtihani. Sasa unaweza kutegemea toleo la hivi karibuni kukupa msingi thabiti wa maarifa ya NEC muhimu kufanya kazi yako kwa usahihi na ujasiri.
