Quizplus · Accepted Answer

The most common type of dimmer used in residential applications is rated at 600 watts, which is suitable for controlling the lighting of a room or a group of smaller rooms. Dimmers rated below 600 watts may not be powerful enough for larger rooms or multiple fixtures, while those rated above 600 watts may be used for commercial or industrial applications. The voltage and frequency ratings of 125 VAC and 60 hertz are typical of standard household electrical systems in North America.
