This standard covers the definition, measurement, and test of characteristics relevant to the use and application of lighting controls and electronic fluorescent ballast.

This standard covers devices rated 120 and 277 VAC, intended to control electronic fluorescent ballast loads up to 16 amps of steady state current.

This standard does not cover or require additional testing for 15 and 20 Amp general-use AC snap switches tested and listed in accordance with UL 20/CSA C22.2 No. 111, which includes a high inrush tungsten lamp load endurance test. They have been evaluated and determined to be compatible with the electronic fluorescent ballasts as described in this publication.
