What is the typical voltage requirement for most luminaires as specified in Article 410?

The correct response indicates that most luminaires typically require 120 volts as specified in Article 410 of the National Electrical Code. This standard voltage aligns with the most commonly used voltage in residential and commercial lighting applications across the United States.

Understanding this requirement is crucial for ensuring that luminaires are compatible with the electrical systems in place. It prevents the risks associated with over-voltage or using fixtures that are not designed for the typical 120-volt supply, which could lead to equipment damage or safety hazards.

Additionally, while other voltages like 240 volts may be used for specific industrial or specialty applications, they are not the standard for general luminaires in most installations.
