30、ctrical Inspections for Existing Dwellings 2016 Edition This edition of NFPA 73, Standard for Electrical Inspections for Existing Dwellings, was prepared by the Technical Committee on Electrical Systems Maintenance and released by the Correlating Committee on National Electrical Code (NEC). It was i

31、ssued by the Standards Council on May 26, 2015, with an effective date of June 15, 2015, and supersedes all previous editions. This edition of NFPA 73 was approved as an American National Standard on June 15, 2015. Origin and Development of NFPA 73 NFPA began the development of NFPA 73, Standard for

32、 Electrical Inspections for Existing Dwellings, in 1990. The document was initiated in response to data obtained from studies conducted on older homes by NFPA, the National Institute of Standards and Technology (NIST), the Consumer Product Safety Commission (CPSC), and other groups involved with re

33、investigations. The studies indicated that res and other hazards attributed to electrical causes would be signicantly reduced if electrical systems were installed and maintained in accordance with NFPA 70, National Electrical Code (NEC). One of the studies reported that only 5 percent of res occurre

34、d in dwellings under 10 years of age, an indication of the effectiveness of the NEC and electrical inspections at the time of construction. The study also suggested that identication and correction of unsafe conditions in existing dwellings by means of appropriate inspections could effectively elimi

35、nate a signicant portion of the residential re occurrences and other associated hazards. The original code was developed as a result of the united efforts of various insurance, electrical, construction, inspection, utility, and other allied interests. A rst draft was published in 1993, which allowed

36、 the study and evaluation of the document prior to formal action at the 1993 NFPA Fall Meeting. The rst edition of NFPA 73, Residential Electrical Maintenance Code for One- and Two-Family Dwellings, was adopted as the 1994 edition. The second edition of the document was submitted for formal adoption

37、 at the 1996 NFPA Annual Meeting Signicant changes to the 2000 edition included a new title, Electrical Inspection Code for Existing Dwellings, and an expanded scope. Because deterioration of electrical systems could occur in existing multifamily dwellings and mobile and manufactured homes as well a

38、s one- and two-family dwellings, the scope was changed to include all dwelling units, including multifamily dwellings and mobile and manufactured homes. The code could then be used to improve the safety of electrical systems in all dwelling units. The change in the title from “maintenance” to “inspe

39、ction” reected the intended purpose of the document. The 2006 edition consisted of editorial revisions of the code to comply with the 2004 edition of the Manual of Style for NFPA Technical Committee Documents. For the 2011 edition, the title was again changed, to Standard for Electrical Inspections

40、for Existing Dwellings to facilitate its use within the home inspection community. This change was made to assist inspectors, who are not code enforcement ofcials, by allowing them to utilize the standard for inspections and thereby improve the electrical safety in dwelling units. Several changes we

41、re made to address issues identied in the Fire Protection Research Foundations technical report Residential Electrical System Aging Research Project. The dismantling of 30 homes, originally constructed from 1892 to 1972, revealed several areas that required investigation, examination, or inspection.

42、 Potential re hazards were identied, including incorrect conductor insulation for wiring of luminaires, multiple conductors terminated on a single terminal, and insulation in direct contact with luminaires not designed for the application. Shock hazards were also identied, such as conductors or cabl

43、es used inappropriately, ground-fault circuit interrupterELECTRICAL INSPECTIONS FOR EXISTING DWELLINGS 73-2 2016 Edition (GFCI) receptacles incorrectly wired, and the grounded conductor attached to normally non-current-carrying metal parts. Changes were made to the standard to address those concerns

44、. Annex tables were added to assist in determining when requirements for arc-fault circuit interrupters (AFCIs) and GFCI were added to the NEC. With the knowledge of which NEC edition was in place at the time of the construction or renovation, users of the standard could easily determine where AFCI

45、and GFCI protection was necessary. Several minor changes have been made to the 2016 edition to correlate the text with that in the NEC. Annex tables for AFCI and GFCI protection have been reformatted to provide easier reference to areas within a dwelling and to the NEC edition in effect. Carbon mono

46、xide detectors have been added to the inspection criteria, and re alarm requirements have been claried.COMMITTEE PERSONNEL 73-3 2016 Edition Correlating Committee on National Electrical Code Michael J.
