What designation is used for overhead power lines that are less than 600 volts?

The designation for overhead power lines that are less than 600 volts is known as low voltage lines. This classification is essential for ensuring safety and proper installation in residential and commercial electrical systems. Low voltage lines are typically used for utilities, lighting, and other applications where the voltage does not exceed this threshold, which allows for certain installation practices and materials that are less stringent compared to higher voltage systems. Understanding these classifications helps electricians and safety professionals to adhere to the appropriate codes and standards, thus ensuring compliance and enhancing safety protocols in electrical work.
