Fast-track getting up to speed with major changes to the
code and implementing the most current electrical installation requirements.

The NFPA 70^®,  National Electrical Code^® (NEC^®) Handbook, is
the most practical and powerful resource today for electrical design and
installation. You get the complete text of the latest NEC plus a range of
features providing insights and guidance on its application.

Only the NEC handbook, 2023 edition, offers:

• Integrated
      expert commentary positioned in line with NEC text


• Summary
      of Technical Changes table demonstrating where and why code changes
      occurred between editions


• A
      cross-reference feature to help you quickly find related information in
      other articles or sections


• Hundreds
      of full-color photos and illustrations, including schematics, floor plans,
      and cross-sectional graphics

Key revisions to NEC 2023 include:

• New
      general criteria for all electrical systems, including a rule
      requiring level/flat surfaces within the working space for electrical
      equipment and expanded provisions covering the use and approval of
      reconditioned electrical equipment


• Changes
      impacting residential electrical systems, ranging from expanded
      ground-fault circuit interrupters (GFCI) requirements for specific
      appliances and new requirements for optional installation of receptacle
      outlets serving island and peninsular countertops and work surfaces


• Introduction
      of commercial/industrial electrical systems requirements for GFCI
      for special appliances, the use of replacement panelboards, and expansion
      of arc-fault circuit interrupter (AFCI) protection provisions


• Increased
      focus on alternative energy systems and emergency management, including
      revised requirements on the interconnection of distributed on-site power
      supplies with electric utility supplies, edits to Article 480 to delineate
      storage battery systems from energy storage systems (ESS), and new rules
      on commissioning of ESS


• New
      articles and requirements for never-before covered systems and equipment such
      as Class 4 fault-managed circuits, hazardous locations within commercial
      and industrial cannabis production facilities, equipotential bonding in
      and around areas with splash pads, insulated bus pipe/tubular covered
      conductor systems, and more
