Which voltage is classified as Extra Low Voltage?

Extra Low Voltage (ELV) is classified as any voltage level that is not likely to cause harm to a person, specifically designed to be safe under normal conditions. The standard commonly referenced for ELV is 30 Volts or less.

This classification is important for ensuring safety in electrical installations, particularly in environments where there is a risk of electrical shock. When operating at this voltage level, the likelihood of severe shock or injury is considerably reduced, making it suitable for various applications, particularly in low-voltage systems.

Choosing a voltage higher than this could potentially increase the risk of electric shock, which is why compliance with the ELV criteria is crucial for safe design and operation of electrical systems. Thus, 30 Volts or less is recognized as the threshold for what constitutes Extra Low Voltage.
