What is the minimum voltage for low voltage lighting systems?

The correct answer identifies that low voltage lighting systems are classified as those operating at 30 volts or less. This standard is widely accepted in many electrical codes and practices, including those relevant in Colorado.

Low voltage lighting systems are commonly used for a variety of applications such as landscape lighting, low voltage indoor fixtures, and certain types of signage. Operating within this voltage range reduces the risk of electric shock, making these systems safer for installation in areas where people might come into contact with the wiring or fixtures.

In understanding the context, it's critical to note that while other voltage levels are referenced, neither 15 volts, 24 volts, nor 50 volts aligns with the established definition of low voltage lighting systems. Systems classified at these levels may fall outside of safety classifications and specific installation standards designated for low voltage applications. 30 volts or less provides a clear and practical threshold that emphasizes safety while still allowing for effective lighting solutions.
