    Electrical failures or malfunctions are the second leading cause of home fires in the US, resulting in hundreds of fatalities, more than a thousand injuries, and over a billion dollars in property damage each year. NFPA 73, Standard for Electrical Inspections for Existing Dwellings, provides inspection and testing procedures and practices for identifying electrical fire and shock risks in one- and two-family homes, multifamily dwellings with three or more units, mobile homes, and manufactured homes.

    The standard covers areas requiring investigation, examination, or inspection, ranging from incorrect conductor insulation temperature for wiring of luminaries to the inappropriate use of conductors or cables.

    Promote public safety in your community with NFPA 73, 2021 edition.

    Inspectors, managers, and homeowners use NFPA 73 to verify the safety of electrical systems and determine compliance objectives prior to the sale of existing dwellings or during and after renovations. The standard features updated extracts to NFPA 70®, National Electrical Code®, 2017 edition, and new inspection items that include the improper replacement of receptacles and the improper use of extension cords to suspend lights and fans.

    Identify electrical fire and shock risks and keep existing homes up-to-code with the 2016 edition of NFPA 73.

    Developed by NFPA®, the NEC® source, for the home inspection community along with apartment complex managers and homeowners, NFPA 73: Standard for Electrical Inspections for Existing Dwellings has the latest provisions home inspectors need for verifying the safety of electrical systems in one- and two-family homes, multi-family dwellings with three or more units, mobile homes, and manufactured homes.

    Determine compliance objectives based on the NFPA 70®, National Electrical Code® (NEC).

    The 2016 NFPA 73 helps users identify AFCI and GFCI protection requirements by NEC edition. Updated, user-friendlier Annex tables show when and where AFCI and GFCI protection were required, so it's easy to look up provisions based on the year the dwelling was built.

    Confidently pinpoint dangerous fire and shock risks.

    Potential fire and shock hazards in aging homes are classified with coverage of topics in a technical report issued by the Fire Protection Research Foundation. NFPA 73 calls out areas that require investigation, examination, or inspection, including coverage of incorrect conductor insulation temperature for wiring of luminaries, and inappropriately used conductors or cables.

    Consult NFPA 73 prior to an existing dwelling sale and during/after renovations.

    Promote public safety in your community with thorough inspections of electrical systems in existing dwellings. Insist on the latest edition of NFPA 73. (Print, 17 pp., 2016)
