What voltage level is considered high voltage?

High voltage is generally defined based on specific thresholds that vary across industries and applications. In many contexts, a voltage level is considered high voltage when it exceeds the standard low voltage thresholds set by electrical safety regulations.

For various international standards, such as those from the International Electrotechnical Commission (IEC), voltages above 50V are often classified as high voltage, especially in the context of electrical safety. However, in certain cases, especially when dealing with certain equipment and environments, voltages above 30V can start to enter the high voltage classification due to increased risk and safety concerns.

Given this context, labeling 30V as a high voltage reflects an understanding of the importance of safety at these levels. At or above 30V, there is a significantly higher risk of electric shock or arcing, which necessitates additional safety measures. Therefore, identifying 30V as the correct response aligns well with safety standards and the thresholds that are commonly acknowledged across the industry.
