Voltages are typically considered high at levels of 120 volts and above in many electrical codes and standards. This is significant because the classification of voltage levels affects safety measures, equipment design, and regulatory compliance. At or above this threshold, additional safety precautions are often required to protect both the users and the equipment from potential hazards.

In domestic and light commercial settings, standard voltages such as 120V are commonly used. However, once the voltage reaches this level or higher, the risks associated with electrical shock and equipment failure increase, warranting more stringent safety protocols. Understanding this classification is crucial for electricians, as it informs their work practices and adherence to safety regulations, ensuring safer environments for both workers and users.
