The 1965 Massachusetts Electrical Code, established by the Board of Fire Prevention Regulations, sets forth the rules for installing, repairing, and maintaining electrical wiring and fixtures used for lighting, heating, and power in buildings. It aligns with the 1965 edition of the National Electrical Code (NEC) with specific modifications tailored for Massachusetts. These modifications include changes in terminology, requiring mandatory compliance rather than recommendations, and introducing state-specific inserts in place of some NEC sections.
This code aims to ensure the safety of people and property from electrical hazards. It mandates that all electrical installations, repairs, and maintenance are performed safely and in accordance with the provisions outlined. While the code aims to prevent hazards, it acknowledges that installations may not always be efficient or sufficient for future electrical demands. It highlights the importance of initial installations being adequate and adaptable to future changes.
The Massachusetts Electrical Code covers the installation of electrical conductors and equipment in various settings, including public and private buildings, industrial sites, and mobile homes. However, it excludes installations related to mines, ships, railway cars, aircraft, and utility-specific installations.
The code is organized into chapters, with general rules outlined in the first four chapters, and special conditions addressed in chapters five through seven. Communication system installations are covered independently in chapter eight, while chapter nine contains tables and examples. The code also includes definitions of key terms used across multiple sections and emphasizes the importance of using recognized methods and standards to achieve the objectives of electrical safety.
