About This Item

 

Full Description

Preface

This is the harmonized UL and CSA Group Standard for Solid State Dimming Controls. It is the second edition of CSA C22.2 No. 184.1 and the second edition of UL 1472. This edition supersedes the one published on January 2, 1996.

For products intended for use in Canada, general requirements are given in CAN/CSA-C22.2 No. 0.

Scope

1.1
These requirements cover permanently installed devices, hereafter referred to as dimmers, that employ a dimming function intended for control of lighting loads of the magnetic ballast, transformer, electronic ballast, self-ballasted lamp, tungsten-filament type, or light-emitting-diode (LED), and are intended to be installed in a wallbox or are provided with an enclosure for flush or surface mounting in accordance with the Canadian Electric Code, Part 1 (CEC), and the National Electrical Code (NEC), ANSI/NFPA 70.

1.2
These requirements cover dimmers, other than touch dimmers, rated 600 volts ac or less, for installation on a 20-ampere or less branch circuit.

1.3
These requirements cover touch dimmers rated 120 volts ac or less for installation on a 20-ampere or less branch circuit.

1.4
These requirements cover dimmers, including touch dimmers, and electronic switches, having a minimum power rating of 300 watts incandescent or 300 volt-amperes in increments of 50 watts or 50 volt-amperes.

1.5
Devices may have additional current ratings based upon the additional lighting loads as specified by the manufacturer.

1.6
A device incorporating other functions (for example, speed control) in addition to a dimming function is investigated on the basis of compliance with the applicable requirements for the dimming function in this Standard as well as requirements for the other functions in the applicable standards.

1.7
These requirements do not cover dimmers that use only a resistor or a transformer to perform the dimming function.

1.8
These requirements do not cover modular, cabinet or console type constructions.

1.9
These requirements do not cover dimmers intended primarily for use in theaters. Dimmers for use in theaters are covered by the Standard for Industrial Control Equipment, UL 508/CSA C22.2 No. 14.
