What is the maximum allowable voltage for low-voltage lighting systems?

The maximum allowable voltage for low-voltage lighting systems is 30 volts. This limit is set to ensure safety for both the installation and users. Low-voltage systems, including outdoor and landscape lighting, are designed to minimize the risk of electrical shock. By keeping the voltage below 30 volts, the risk associated with potential accidental contact with live wires is significantly reduced, making it safer for outdoor use and in areas where people may come into contact with the fixtures.

The designation of 30 volts is recognized in various electrical codes, including the National Electrical Code (NEC), which helps standardize practices regarding electrical installations. It categorizes these systems as "low voltage," thus creating a guideline for electrical contractors and installers to follow when designing and implementing safe lighting solutions.
