The code you know and use—revamped to keep pace with
ever-evolving electrical hazards and challenges.

NFPA 70^®, National Electrical Code^® (NEC^®),
is the authoritative document addressing electrical installations in
residential, commercial, and industrial settings. Stay up to date as you
design, install, and inspect with the most current requirements. The NEC has
been revised and expanded to stay in sync with industry practices,
emerging trends, and the development and introduction of technologies. The
document is completely reorganized for improved ease of use and features an
expanded Article 100 that consolidates all the code's defined terms in one
place to help you quickly locate critical NEC content.

Changes in the 2023 NEC include new, expanded, and
revised content and provisions for:

• All
      electrical systems, including the use and approval of
      reconditioned equipment, level/flat standing surfaces within the required
      working space for electrical equipment, servicing and maintenance of
      equipment, and opened electrical equipment doors that impede access to or
      egress from required equipment workspace


• Residential
      electrical systems covering ground-fault circuit interrupters
      (GFCI) for specific appliances, optional installation of receptacle
      outlets serving island and peninsular countertops and work surfaces,
      emergency disconnects of one- and two-family dwellings, the use of 10-ampere
      branch circuits, and an annex providing guidelines on the use of
      electrically powered medical equipment in homes and residential board and
      care occupancies


• Commercial/industrial
      electrical systems accounting for everything from GFCI for
      specific appliances and the use of "replacement panelboards" to
      arc-fault circuit interrupter (AFCI) protection of sleeping areas of
      public safety and first responder facilities, disconnecting means in sight
      of luminaires using double-ended lamps to include LED type, and other
      considerations


• Alternative
      energy systems and energy management addressing the
      interconnection of distributed on-site power supplies with electric
      utility supplies, the delineation between storage battery systems and
      emergency storage systems, commissioning energy storage systems (ESS),
      photovoltaic electric systems, emergency management systems, load
      calculations for outlets supplying electric vehicle supply equipment, and
      solar photovoltaic and wind power electric systems on floating structures
      and in offshore locations


• 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, flexible bus systems, germicidal irradiation lighting
      equipment, and more


• The
      document is completely reorganized for improved ease of use and
      features an expanded Article 100 that consolidates all the code's defined
      terms in one place to help you quickly locate critical NEC content.
