Photovoltaics, along with other renewable-energy technologies, is a rapidly growing sector of the energy market. Photovoltaic Systems, Second Edition, is a comprehensive guide to the design, installation, and evaluation of residential and commercial photovoltaic (PV) systems. The textbook covers the principles of photovoltaics and how to effectively incorporate PV systems into stand-alone or interconnected electrical systems. The content includes system advantages and disadvantages, site evaluation, component operation, system design and sizing, and installation requirements and recommended practices. Common scenarios and procedures are discussed throughout.

Rewritten and extensively updated, the full-color 2017 edition NEC® Handbook is the most practical and powerful resource for electrical design and installation today. Success in the electrical industry depends on your grasp of NFPA 70®: National Electrical Code® requirements and your ability to apply them correctly. Based on the 2017 NEC, the NEC Handbook clarifies concepts for a better understanding of the Code. It's a powerful communication tool that helps you explain the NEC to clients and others who might not have professional electrical training. The new NEC Handbook reflects industry trends and Code changes that impact residential, commercial, and industrial work. Order the 2017 edition of the NEC Handbook, the resource trusted by electrical contractors, engineers, electricians, safety officials, inspectors, and architects nationwide.

Throughout the United States and around the world, NFPA 70: National Electrical Code (NEC) sets the foundation for electrical safety in residential, commercial, and industrial occupancies. The 2017 edition of this trusted Code presents the latest comprehensive regulations for electrical wiring, overcurrent protection, grounding, and installation of equipment. Major additions reflect the continuing growth in renewable power technology. Other NEC revisions protect the public and workers from deadly hazards. Work with the latest requirements governing public and private buildings, homes, and structures; outdoor yards and lots; utility equipment; installations that connect to the power grid; and consumer-owned power generation systems and equipment. The 2017 NEC is better aligned with the safe work practices in NFPA 70E: Standard for Electrical Safety in the Workplace.

The NEC, 2020 edition, introduces significant new requirements for:

• The residential installation of receptacle outlets serving island and peninsular countertops and for surge protection of services supplying dwelling units
• Working space for “housekeeping pads” for electrical equipment, the installation of wiring methods in exit enclosures, sizing supply and load conductors used with adjustable-speed drive systems, and AFCI protection of branch circuits in patient sleeping areas in care facilities
• Calculating the load of electric vehicle supply equipment with variable current settings
• Worker safety in identifying the source of power for disconnecting means and for egress from spaces containing large electrical equipment
• Grounding of disconnecting means installed on the supply-side of service disconnecting means
• Cables installed exposed on ceiling surfaces and sidewalls
• Special occupancies, special equipment, and special conditions, including installation of splash pads, the use of “Type P” cables in hazardous classified locations, and the reinspection of swimming pools and other bodies of water
