Within which range does low voltage fall?

Low voltage is defined by specific thresholds, and the correct answer falls within the widely accepted regulatory range for low voltage systems. Specifically, low voltage is categorized as being within the range of 50V to 1200V AC or 120V to 1500V DC. This classification is important for safety standards and regulatory compliance.

The rationale for this classification stems from safety considerations; voltages below these thresholds generally pose a lower risk of electric shock and are often utilized for residential and commercial applications. Equipment rated within this range can typically be handled with standard safety equipment and practices, promoting broader use in various electrical installations.

Understanding these voltage classifications is critical for electrical workers and engineers, ensuring that they select appropriate equipment, materials, and protection schemes tailored to the application they are working on. Familiarity with the definitions around voltage types also aids in compliance with electrical codes and improves overall safety in electrical work.
