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

NEC Self-Adhesive Index Tabs mark electrical topics by code article and name. For the 2020 edition, tabs are organized by color to help users quickly find the corresponding subject matter. Only the 2020 edition has tabs that are organized by color to help users quickly find the corresponding subject matter. Previous editions are available in black and white.

Volume B30.17 includes provisions that apply to the construction, installation, operation, inspection, and maintenance of hand-operated and power-driven overhead and gantry cranes that have a top-running single-girder bridge, with one or more underhung hoists (see B30.16 Volume)operating on the lower flange of the bridge girder, used for vertical lifting and lowering of freely suspended, unguided loads (see Figs. 1 through 5). The requirements included in this volume also apply to cranes having the same fundamental characteristics such as polar gantry cranes, cantilever gantry cranes, semi-gantry cranes, and wall cranes. Requirements for a crane used for a special purpose such as, but not limited to, non-vertical lifting service, lifting a guided load, or lifting personnel are not included in this volume.
