ANSI C82.77-10-2024
Lighting Equipment - Harmonic Emission Limits - Related Power Quality Requirements
Specifies power quality limits, factors, and methods of measurement for lighting equipment. This standard covers all types of lighting equipment that are used for general illumination (typically found in residential, commercial, and industrial applications) and that are connected to any of the following commonly distributed 60 Hz alternating current (AC) power line systems: 120 V, single phase; 220/230 V, single phase; 208/240 V, single phase; 277V, 347 V, single phase; 480 V, single phase; 480V/347 V, 3 phase. Note: These line voltages are nominal and include commonly encountered nameplate variations of the above. As an example, products rated at either 117 V, 120 V, or 125 V AC would be covered as being inclusive of nominal 120 V systems.
