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

Expanded and updated, NFPA 72®, National Fire Alarm and Signaling Code® reflects the latest technologies, applications, and research.

Update to the new benchmark for fire alarm systems, with requirements that reflect code user needs and concerns in the field today. The 2019 edition of NFPA 72, National Fire Alarm and Signaling Code presents the most advanced provisions ever developed for the application, installation, location, performance, and inspection, testing, and maintenance of fire alarm and emergency communications systems -- including Mass Notification Systems (MNS).

This edition features important updates for designers, installers, and AHJs—from added testing requirements for Energy Storage Systems (ESS), to new requirements for HVLS fans and air-sampling smoke detectors.

In a major change to scope, NFPA 72 now addresses carbon monoxide protection.

Material previously in NFPA 720, Standard for the Installation of Carbon Monoxide (CO) Detection and Warning Equipment is relocated into the 2019 edition of NFPA 72. Critical requirements are incorporated into:

• Chapter 17 for carbon monoxide detectors
• Chapter 14 for installation, testing, and maintenance
• Chapter 29 for carbon monoxide alarms -- with a significant amount of additional information
• New Annex H

Other key changes address occupant evacuation, areas of refuge, and VRLA batteries:

• Major revisions to the requirements for fire service access elevators and occupant evacuation elevators (OEE) coordinate with changes made in ASME A17.1/CSA B44. Annex text is added for clarification.
• Extensively revised requirements for occupant evacuation operation (OEO) coordinate with the new best practices and field research.
• In addition to revised requirements for area of refuge (area of rescue assistance), Chapter 24 now includes requirements for stairway communications systems, elevator landing communications systems, and occupant evacuation elevator lobby communications systems.
• Chapter 14, Inspection, Testing, and Maintenance now incorporates valve-regulated lead-acid (VRLA) batteries.
• New and updated definitions bring NFPA 72 up-to-date with current technologies. For example, the terms strobe, light, and visible are changed to visual notification appliance, recognizing use of LED products that can be used for fire alarm.

The 2019 edition of NFPA 72 is a must-have resource for everyone involved with fire alarm design, installation, inspection, and maintenance. Order direct from NFPA®, the Code source.

Trust the fully revised Fire Alarm Signaling Systems for state-of-the-art guidance that helps make sure your systems meet code.

Equip yourself for success with the new edition of this informative text from authorities at NFPA® and the Society of Fire Protection Engineers (SFPE). Fire Alarm Signaling Systems provides comprehensive coverage of the full range of issues from signal initiation to system testing so you can meet job challenges confidently.

Stay on the leading edge and learn to apply the 2010 NFPA 72® to design, select, and install systems for optimum protection.

Featuring clear non-technical explanations, updated artwork, and an easy-to-use format, this how-to resource enhances your Code knowledge so you can:

• Establish fire protection goals, match the fire alarm system to the goals, and know system limitations
• Effectively design a mass notification system
• Weigh the benefits of prescriptive versus performance-based design approaches
• Maintain quality control during installations
• Analyze and improve intelligibility of voice communication systems
• Understand the elements and importance of a well-designed fire service interface
