What is the voltage range classified as low voltage in electrical installations?

The classification of low voltage in electrical installations is typically defined as the range from 0 to 50 volts. This classification is important because it distinguishes low voltage systems, which have specific safety and operational guidelines, from higher voltage systems that may pose greater risks and require different handling methods.

In many electrical codes and standards, such as those outlined by organizations like the National Electrical Code (NEC), low voltage systems are recognized for their applications in control circuits, signal circuits, and certain lighting systems, allowing them to operate at a minimal risk of electrical shock. For electric professionals, understanding this range is critical for ensuring safety and compliance with regulations when working on or around low voltage installations.
