Prepare for the electrical challenges of tomorrow, today, with NFPA 70, National Electrical Code (NEC), 2020 edition.

The world never stops changing, so it's crucial to keep learning how to keep it safe. Incorporated by reference in all 50 states and used across the globe, NFPA 70®, National Electrical Code® (NEC®), is the benchmark standard for electrical safety in residential, commercial, and industrial settings.

NFPA 70, NEC, was first published in 1897 and is continually put through a rigorous review process to keep it up to date with the most current industry practices, emerging trends, and the development and introduction of new technologies. The new NEC provides the latest requirements for safer and more effective electrical design, installation, and inspection, including provisions for wiring, overcurrent protection, grounding, and equipment.

Get up-to-code and prepared for the safety challenges of new sources of electrical power with the NEC, 2020 edition.

The revised and expanded NFPA 70, National Electrical Code, features state-of-the-art information for safe electrical practices for 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.

Content has been added, edited, and reorganized to address safety for workers, energy systems and electric vehicles, limited energy, and communication systems.

Impactful changes include:

• New requirements for exterior emergency disconnects of one- and two-family dwellings for improved electrical safety for emergency responders
• Revisions to service disconnect rules to help protect electrical workers from arc flash hazards
• Adapted and adjusted requirements for installation practices of new technologies to meet the evolving demand of power over Ethernet
• Updates to modernize tables currently in use for calculations to reflect improvements in energy efficiency and align with evolving codes
• Revised requirements for ground-fault protection within marinas and boatyards
• Introduction of guidelines for the safe use of electric vehicles (electric vehicle power export equipment) as a backup or emergency power source for a building or a home
• Reorganization of Article 310, including new user-friendly numbering for important ampacity tables, and new definition for cable bundle in Article 725
• Relocation of surge protection device requirements to new Article 242
• Revisions to alternative energy systems and electric vehicle requirements to clarify what portions of the PV system are covered by the requirements of Article 690 and the line side and load side connections of interconnected power supply sources, and to clearly distinguish energy storage systems from storage battery systems
• Reorganization of Article 800 to provide a general set of requirements to apply throughout the Chapter 8 articles
• Revisions to requirements for communications cables that are also carrying power to communication devices and revisions to the current limit for cables carrying power and data

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

Help protect life and property with the most relevant electrical requirements.

Manual D includes a number of informative appendices related to air distribution systems (e.g., equipment and air-side components, controlling excess air when VAV dampers close, duct loads, duct leakage and duct system efficiency, air quality issues, noise control, minimum air velocity for ducts; codes, standards and best practice issues; and commissioning issues). The Manual D has been significantly revised to include:

• Updated and expanded VAV guidance, with detailed examples
• Impacts of excess length, sag and compression in flexible ducts
• New equivalent length values for flex duct junction boxes

Manual D provides:

• A single set of ANSI-recognized duct sizing principles and calculations that apply to all duct materials
• System operating point (supply Cfm and external static pressure), and airway sizing for single-speed and multi-speed (ECM) blowers
• A method for determining the impact of duct friction and fitting pressure drop on blower performance and air delivery
• The most comprehensive equivalent length data ever published

You can apply the Manual D procedure to constant volume systems and zoned variable air volume systems, over a full range of duct construction materials. Manual D includes a number of informative appendices related to air distribution systems (e.g., equipment and air-side components, controlling excess air when VAV dampers close, duct loads, duct leakage and duct system efficiency, air quality issues, noise control, minimum air velocity for ducts; codes, standards and best practice issues; and commissioning issues).

Manual J 8th Edition is the national ANSI recognized standard for producing HVAC equipment sizing loads for single-family detached homes, small multi-unit structures, condominiums, town houses, and manufactured homes. A proper load calculation, performed in accordance with the Manual J 8th Edition procedure, is required by national building codes and most state and local jurisdictions.
