Low voltage systems are classified as those that operate at 600 volts or less. This classification is based on standards set by organizations like the National Electrical Manufacturers Association (NEMA) and the National Fire Protection Association (NFPA). These classifications help ensure safety and standardization across electrical systems, particularly for installation and maintenance activities.

Systems operating within this voltage range are generally considered to pose lower electrical hazards compared to higher voltage systems. As a result, safety protocols, equipment design, and protective measures differ significantly for low voltage systems compared to those classified at medium and high voltage levels. This distinction is essential in developing an understanding of the risks and required safety practices when working with different types of electrical systems.

The higher voltage ranges, such as 240 to 480 volts, and particularly those above 600 volts, introduce additional risks that require more stringent safety measures and training for personnel, which is not the case for systems that fall under the 600 volts threshold.
