The NFPA 73-2021 standard is a comprehensive guide that aims to ensure electrical safety and compliance in existing homes. Electrical failures and malfunctions are a significant cause of home fires, injuries, and property damage, making it crucial to have proper inspection and testing procedures in place.

This standard covers various areas that require investigation, examination, or inspection, including issues such as incorrect conductor insulation temperature for wiring of luminaries and the inappropriate use of conductors or cables. By adhering to NFPA 73, inspectors, managers, and homeowners can verify the safety of electrical systems and establish compliance objectives. This is particularly important during the sale of existing dwellings or renovations.

The 2021 edition of NFPA 73 incorporates updated information from NFPA 70, the National Electrical Code® from the 2017 edition. Additionally, it introduces new inspection items like the improper replacement of receptacles and the misuse of extension cords to suspend lights and fans.
