After building your skills you can test your knowledge with the two Final Exams in the back of the book. NFPA Identify electrical fire and shock risks and keep existing homes up-to-code with the edition of NFPA Standard for Electrical Inspections for Existing Dwellings has the latest provisions home inspectors need for verifying the safety of electrical systems in one- and two-family homes, multi-family dwellings with three or more units, mobile homes, and manufactured homes.

Updated, user-friendlier Annex tables show when and where AFCI and GFCI protection were required, so it's easy to look up provisions based on the year the dwelling was built.

One- and Two-Family Dwelling Electrical Systems has been developed for those involved in design, installation, or inspection of electrical systems in new and existing dwellings. Now in its Tenth edition , this book explains the design, installation and inspection of electrical systems in new and existing one- and two-family dwellings. Printreading Based on the NEC -.

Different types of prints used in industry are represented throughout the textbook, including plot plans, floor plans, and elevations. Prints are also used in conjunction with code requirements to determine dwelling load calculations. This textbook serves as both an instructional tool and a valuable technical reference for professionals in the field. Improving your skills in electrical grounding and bonding has never been easier!

If you are serious about your knowledge and skills, your technical library is incomplete without this book!

On the one hand, you need to keep job costs down. On the other hand, your electrical projects must meet code. Even common applications make NEC training essential. For example, consider those tables in Article Do you really understand how to size conductors?

Do you understand when to use the 90 degree column and when not to? Do you know when to use Table How do you apply these tables when sizing feeders for motor circuits? What about motor branch circuits? A wrong answer to any of these questions can be costly. Those who fail to adhere to well known best practices for safety have been held negligent.

This liability and the desire to protect residents has motivated cities to adopt and enforce building codes that specify standards and practices for electrical systems as well as other departments such as water and fuel-gas systems. This creates a system whereby a city can best avoid lawsuits by adopting a single, standard set of building code laws. This has led to the NEC becoming the de facto standard set of electrical requirements.

Department of Energy DOE facilities. The additional guidance is needed to clarify the current electrical code for these situations.

Public access[ edit ] The NEC is available as a bound book containing approximately pages. It has been available in electronic form since the edition.

Although the code is updated every three years, some jurisdictions do not immediately adopt the new edition. The NEC is also available as a restricted, digitized coding model that can be read online but not saved, copied and pasted, or printed, free of charge on certain computing platforms that support the restricted viewer software.

In the United States, statutory law cannot be copyrighted and is freely accessible and copyable by anyone. Once the coding model has been accepted as law, it loses copyright protection and may be freely obtained at no cost. The introduction sets forth the purpose, scope, enforcement and rules or information that are general in nature. The first four chapters cover definitions and rules for installations voltages, connections, markings, etc. The next three chapters deal with special occupancies high risk to multiple persons , special equipment signs, machinery, etc.

Annexes A-J relate to referenced standards, calculations, examples, additional tables for proper implementation of various code articles for example, how many wires fit in a conduit and a model adoption ordinance.

The introduction and the first 8 chapters contain numbered articles, parts, sections or lists or tables italicized exceptions, and Informational notes — explanations that are not part of the rules. Articles are coded with numerals and letters, as. For example, Each code article is numbered based on the chapter it is in. Those wiring methods acceptable by the NEC are found in chapter 3, thus all approved wiring method code articles are in the s.

Efforts have been underway for some time to make the code easier to use. Some of those efforts include using the same extension in those code articles for the support of wiring methods. The NFPA also publishes a 1,page NEC Handbook for each new NEC edition that contains the entire code, plus additional illustrations and explanations, and helpful cross-references within the code and to earlier versions of the code.

The explanations are only for reference and are not enforceable. Many NEC requirements refer to "listed" or "labeled" devices and appliances, and this means that the item has been designed, manufactured, tested or inspected, and marked in accordance with requirements of the listing agency.

Upon payment of an investigation fee to determine suitability, an investigation is started. To be labeled as fit for a particular purpose for example "wet locations", "domestic range" a device must be tested for that specific use by the listing agency and then the appropriate label applied to the device. A fee is paid to the listing agency for each item so labeled, that is, for each label. Most NRTLs will also require that the manufacturer's facilities and processes be inspected as evidence that a product will be manufactured reliably and with the same qualities as the sample or samples submitted for evaluation.

An NRTL may also conduct periodic sample testing of off-the-shelf products to confirm that safety design criteria are being upheld during production. Because of the reputation of these listing agencies, the "authority having jurisdiction" or "AHJ" — as they are commonly known usually will quickly accept any device, appliance, or piece of equipment having such a label, provided that an end user or installer uses the product in accordance with manufacturer's instructions and the limitations of the listing standard.

However, an AHJ, under the National Electrical Code provisions, has the authority to deny approval for even listed and labeled products. Likewise, an AHJ may make a written approval of an installation or product that does not meet either NEC or listing requirements, although this is normally done only after an appropriate review of the specific conditions of a particular case or location.

The Code has user-friendly features to aid the reader in seeing changes.

Revisions or additions to the articles from the version are highlighted in gray shading. For circuits defined as low voltage, in some jurisdictions, there is no requirement for licensing, training, or certification of installers, and no inspection of completed work is required, for either residential or commercial work.

Low voltage cabling run in the walls and ceilings of commercial buildings is also typically excluded from the requirements to be installed in protective conduit. In more recent terms, the upper cutoff for what is considered low is approximately 50 Volts, with most computer network equipment operating at 48 Volts DC or lower, and not requiring special training to connect or use.Extremely reader friendly, it offers detailed--but not overly technical--explanations as it guides you step by step through the critical tasks and responsibilities that face today's professional residential electricians in both new construction and existing homes.

The receptacle assemblies must be listed to ensure that they have been evaluated to function properly when exposed to conditions, such as liquid spills and splashing, likely to be encountered in countertop installations.

It explores each room of the house in detail, including receptacle placement, smoke detector installation, stairwells, and crawl spaces. As of the NEC required that new Volt household receptacle outlets, for general purpose use, be both grounded and polarized. The concern is that the redundant grounding required by Sections GFCI devices come in many configurations including circuit-breakers, portable devices and receptacles.
