What voltage is considered low voltage in electrical installations?

The classification of low voltage in electrical installations is commonly defined as voltage that is typically below 50 volts AC or 120 volts DC. This definition aligns with safety standards in electrical work, where low voltage systems are often used to minimize the risk of electric shock and ensure safer operation of equipment.

In many contexts, voltages below these thresholds are considered low enough to allow for safer handling and reduced likelihood of injury during maintenance or installation. This is particularly important when dealing with control circuits, communication systems, or other applications where high voltages could pose a significant hazard.

While other voltages are mentioned in the options, they do not fall within the commonly accepted definitions used in practical applications and safety regulations. Understanding these distinctions is crucial for electrical professionals, as working with the wrong voltage classifications can lead to inappropriate safety measures and compliance issues.
