What is the typical voltage level considered as secondary voltage or low voltage?

In electrical terminology, secondary voltage or low voltage typically refers to voltages used in residential, commercial, and some industrial applications that are safe for general usage. The most widely accepted standard for low voltage is any voltage below 600 volts. This classification is important for safety reasons, as it helps define the scope of work that can be performed by technicians and linemen without requiring specialized high voltage safety training or equipment.

Voltages above 600 volts are considered high voltage and subject to different safety regulations, equipment, and protocols. Therefore, stating that secondary or low voltage is under 600 volts aligns with standard practices and definitions in the electrical industry. This classification aids in understanding the operational differences between various electrical systems and the precautions necessary when working with them.
