簡介:美國消防協(xié)會標準 NFPA70®-2020(英文版)

中文名稱:國家電氣規(guī)范

Lead the way to a safer tomorrow today. Get current with the latest in electrical installation requirements with the reorganized and updated NFPA 70®, National Electrical Code® (NEC®), 2023 edition.

The NEC is the authoritative document addressing electrical installations in residential, commercial, and industrial settings. The 2023 edition represents a significant revision to modernize the code to reflect the rapidly evolving electrical landscape. Stay up to date as you design, install, and inspect with current requirements for wiring, overcurrent protection, grounding, and equipment.

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

The new National Electrical Code is 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.

Whether you are working with Class 4 fault-managed circuits or electrical systems operating over 1000 volts ac/1500 volts dc, you need the 2023 edition of the NEC to help you stay compliant.
