Abstract
International, regional, and national standards for electrical equipment were reviewed. National standards in the United States (US) were listed. More than 150 National Electrical Manufacturers Association and over 200 Underwriters' Laboratories, Incorporated standards related to electrical equipment exist. Although the National Electrical Code is the most widely used standard pertaining to installing electrical equipment, there are many others published by such organizations as the National Fire Protection Association, the American Petroleum Institute, The American National Standards Institute, and the American Society for Testing and Materials. International standards were discussed. Attempts have been made in recent years to standardize and incorporate all international standards into one organization, the International Electrotechnical Commission (IEC). Functions of the IEC were discussed. It was noted that IEC standards have no formal status until they have been adopted by a member country. IEC standards tend generally to be design oriented, whereas US standards are performance oriented. Differences in US and IEC standards as applied to protecting electrical motor circuits and installing cable were discussed. The author concludes that for electrical systems to be safe, both the equipment standards and installation rules must be examined carefully. Electrical equipment that has been designed and tested under one standard may not be safe when installed according to another standard.
