Analysis of Proposals for Compliance and Enforcement Testing Under the New Par 431; Title 10, Code of Federal Regulations



Ken L. Stricklett, M Vangel


Two proposals are evaluated for establishing compliance with the average efficiency levels prescribed by section 342(b)(1) of the Energy Policy and Conservation Act of 1975, as amended (EPCA), Public Law 94-163: The Department of Energy's (DOE's) Proposed Rule for Electric Motors, at 10 Code of Federal Regulations Part 431, sections 431.24 and 431.127, published in the Federal Register, November 27, 1996; and the April 18, 1997, Proposal for the Method of Determining Compliance and Enforcement for Electric Motors under the Efficiency Labeling Program of DOE, 10 CFR Part 431, submitted by the Motor and Generator Section of the National Electrical Manufacturers Association (NEMA). The operating characteristics of the DOE proposal and the NEMA proposal are examined within the context of EPAC: Compliance with the energy efficiency levels for motors prescribed by section 342(b)(1) of EPCA is assumed to be satisfied when the true mean full load efficiency of the population of each basic model of electric motor equals or exceeds the applicable nominal full load efficiency.
