Department of Energy 10 CFR Parts 429 and 430 [EERE-2019-BT-TP-0012] RIN 1904-AD86 AGENCY: Office of Energy Efficiency and Renewable Energy, Department of Energy. ACTION: Notice of proposed rulemaking and request for comment. SUMMARY: The U.S. Department of Energy (“DOE”) is proposing to revise its test procedure for external power supplies (“EPS” or “EPSs”). DOE is proposing to add a definition for “commercial and industrial power supply” in its regulations to differentiate between EPSs and other non-consumer power supplies that are not subject to the test procedure. DOE also proposes to add a definition to address an adaptive EPS that conforms to the Universal Serial Bus Power Delivery (“USB-PD EPS”) specifications and revise its procedure to address their testing in a manner more representative of their actual use. Further, the proposed revisions would provide more specific instructions for testing single-voltage EPSs that have multiple output busses. Lastly, DOE proposes to reorganize the test procedure to centralize definitions, consolidate generally applicable requirements, and better delineate requirements for single-voltage, multiple-voltage, and adaptive EPSs. DOE is seeking comment from interested parties on the proposal. DATES:   Comments: Written comments, data, and information are requested and will be accepted no later than February 4, 2020.
