ANSI C37 Electrical Power Safety Testing: Eurolabs Laboratory Testing Services

Standard-Related Information

The electrical power industry is governed by a complex array of standards, regulations, and laws that ensure the safety and reliability of electrical equipment and systems. Among these, the ANSI C37 standard is one of the most widely recognized and adopted standards globally.

What is ANSI C37?

ANSI C37 is a set of standards published by the American National Standards Institute (ANSI) that covers the testing and evaluation of electrical power equipment, including circuit breakers, switches, and fuses. The standard is designed to ensure that electrical equipment meets certain performance and safety criteria, thereby reducing the risk of electrical shock, fire, and other hazards.

International and National Standards

While ANSI C37 is a US-specific standard, many countries have adopted similar standards or modified versions of ANSI C37 for their local markets. Some examples include:

  • IEC 62271 (International Electrotechnical Commission)

  • IEEE 1527 (Institute of Electrical and Electronics Engineers)

  • EN 60947 (European Committee for Electrotechnical Standardization)

    • Standard Development Organizations

    The development and maintenance of ANSI C37 are overseen by the American National Standards Institute (ANSI), in collaboration with other standard development organizations, including:

  • IEEE (Institute of Electrical and Electronics Engineers)

  • NEMA (National Electrical Manufacturers Association)

  • UL (Underwriters Laboratories)

    • Evolution of Standards

    Standards like ANSI C37 are constantly evolving to reflect new technologies, research findings, and emerging risks. The update process involves a rigorous review and revision cycle, which may involve public comment periods and stakeholder input.

    Specific Standard Numbers and Scope

    Some key standard numbers related to ANSI C37 include:

  • C37.06-2010 (Guide for surge arresters for AC systems)

  • C37.13-2008 (Switchgear Sectionalizers)

  • C37.20.3-2009 (Enclosed low-voltage power circuit breakers)

    • Standard Compliance Requirements

    Compliance with ANSI C37 is mandatory in various industries, including:

  • Electrical equipment manufacturers

  • Power generation and distribution companies

  • Utility providers

  • Government agencies
