higher than the efficiency of a UL 1004
10:2020-compliant variable-speed motor, for which the full-load efficiency metric includes the losses of the integrated drive.20 Nidec asserted that requiring a full-load efficiency metric on the motor nameplate would be confusing to the end-user and is detrimental to the success of implementing the rule. Nidec, No. 58
Similarly, Regal Beloit commented that a full-load efficiency metric would not be effective in assisting consumers in making purchasing decisions if singlespeed motors are still allowed on the market. Regal Beloit, Public Meeting Transcript, No. 55 at pp. 4950
The definitions related to DPPP
motors incorporated into this final rule includes variable-speed control DPPP
motors. A DPPP motor, including a variable-speed control DPPP motor, may include a drive which could be physically combined with the motor into a single unit, may include a drive that is physically separate from the DPPP motor, or may not include a drive but the motor is unable to operate without a drive. UL 100410:2020
defines a drive as a power converter such as a variable-speed drive or phase converter. UL 100410:2020 sec. 2.7.
The term drive is used to describe the category of speed controls used in variable-speed control DPPP motors and certain twoand multi-speed DPPP
motors. See UL 100410:2020 sec. 2.11, 2.15, 2.16. When testing motors with drives, the drive cannot always be tested separately from the motor.
As stated, DOE proposed to incorporate by reference CSA C74709
as the prescribed test method for evaluating the energy efficiency of the pool pump motors in scope. 85 FR
62816, 6282262823. When the motor requires a drive to operate, CSA C747
09 provides that testing includes testing of the drive see Section 4 of CSA C747
09.21 Based on its review of catalogs, DOE has determined that DPPP motors that operate with a drive, either have an integrated drive, or are sold in conjunction with a drive including when the motor is unable to operate 20 For example, a motor could have a full-load efficiency of 70 percent compared to a motor 70
percent full-load efficiency and integrated controls 95 percent full-load efficiency with a full-load efficiency of 70 95 = 66.5 percent. Nidec, No. 58
21 CSA C74709 uses the term inverter motor and converter, but as evidenced by the definition in UL 100410:2020, a converter and drive are synonymous. NEMA MG 12016, American National Standard for Motors and Generators paragraph 30.2.1.5 defines the term control as devices that are also called inverters and converters.

without a drive.22 NEMA, PHTA, and the CA IOUs, stated manufacturers test DPPP motors with drives inclusive of the drive. As such, the measured fullload efficiency of the DPPP motor includes the efficiency of the drive if a drive is integrated into the motor, or the motor cannot operate without the presence of a drive.
This final rule maintains the fullload efficiency as the description of the metric for DPPP motors. DOE is concerned that the term motor system efficiency, or some variant, could be misunderstood to mean that the measured value includes the efficiency of components other than the DPPP
motor e.g., as inclusive of the pool pump. In addition, not all DPPP motors include a drive e.g., single-speed DPPP
motors.
To address stakeholder concerns regarding the description of the metric and to reflect the inclusion of the drive, as appropriate, DOE is clarifying that the measured full-load efficiency of the DPPP motor is inclusive of the drive if the DPPP motor is placed into commerce with a drive or is unable to operate without the presence of a drive.
In addition, the provisions of section 4
of CSA C747 would still apply, and DOE
adds that the measured full-load efficiency of the DPPP motor is also inclusive of the drive if the DPPP motor requires a drive to operate, regardless of whether the DPPP motor is sold with a drive.
E. Harmonization With Industry Standards On February 14, 2020, DOE finalized its rule, Procedures for Use in New or Revised Energy Conservation Standards and Test Procedures for Consumer Products and Commercial/Industrial Equipment the Process Rule. 85 FR
8626. The Process Rule requires DOE to adopt industry test standards as DOE
test procedures for covered products and equipment, unless such methodology would be unduly burdensome to conduct or would not produce test results that reflect the energy efficiency, energy use, water use as specified in EPCA or estimated operating costs of that equipment during a representative use cycle. Section 8c of appendix A 10 CFR part 430 subpart C; 10 CFR 431.4.23 In cases where the industry standard does not meet EPCA
22 As the DPPP motors are replacement motors, absent a specific drive identified, the applicable drive would be that in the dedicated-purpose pool pump for which the motor serves as a replacement.
23 This practice implements the National Technology Transfer and Advancement Act and OMB Circular A119 with respect to the adoption of industry standards. See 85 FR 86798680.

statutory criteria for test procedures, DOE will make modifications through the rulemaking process to these standards as the DOE test procedure.
The test procedures for DPPP motors at new subpart Z to part 431
incorporates by reference the test standard CSA C74709 reaffirmed in 2014, Energy Efficiency Test Methods for Small Motors, without modification.
CSA C74709 is an industry-accepted test procedure that measures the energy efficiency of certain motors, and is applicable to DPPP motors in scope sold in North America. CSA C74709
includes specifications for the test setup, instrumentation, test conduct, and calculations. DOE also incorporates by reference UL 100410:2020, Standard for Safety for Pool Pump Motors, without modification, to reference the definitions published in the same standard. UL 100410:2020 establishes definitions and marking requirements for certain pool pump motors and describes methods to verify the information conveyed by those required markings.
F. Effective Date EPCA prescribes that, if DOE
establishes or amends a test procedure, all representations of energy efficiency and energy use, including those made on marketing materials and product labels, must be made in accordance with that test procedure, beginning 180 days after publication of such a test procedure final rule in the Federal Register. 42 U.S.C. 6314d1
If DOE were to establish a new, or amend an existing test procedure, EPCA
provides an allowance for individual manufacturers to petition DOE for an extension of the 180-day period to begin making representations if the manufacturer may experience undue hardship in meeting the deadline. 42
U.S.C. 6314d2 To receive such an extension, petitions must be filed with DOE no later than 60 days before the end of the 180-day period and must detail how the manufacturer will experience undue hardship. Id.
DOE received a number of comments involving the effective and compliance dates focusing on the labeling requirements proposed in the October 2020 NOPR. As DOE is not finalizing that aspect of the October 2020 NOPR, DOE will address those comments in a future rulemaking regarding the labeling requirements.
The effective date for the established test procedure will be 30 days after publication of this final rule in the Federal Register. The test procedure established in this final rule does not require manufacturers to test DPPP
