High voltage is commonly defined in electrical safety contexts as any voltage above a certain threshold that poses increased risks to safety and equipment. Under the discussed guidelines, high voltage is defined as 30 volts excluding communications. This definition is significant because it sets a baseline for safety regulations, design considerations, and operational procedures in environments where electrical systems are utilized.

In this context, the specification of "excluding communications" indicates that the measurement of high voltage does not extend to communication systems which may operate at different voltage levels. This distinction is crucial for electricians and locksmiths, as it delineates which systems are subject to high voltage safety protocols.

The other definitions presented do not align with the traditional criteria for defining high voltage in these guidelines. For instance, higher voltage thresholds, such as 60 or 120 volts, might fall under different categories of voltage classifications that involve various safety measures. However, in this framework, 30 volts is recognized as the starting point where voltage begins to pose additional safety concerns and requires more stringent handling and precautions.
