Low Voltage (LV) is defined as electrical equipment that uses what voltage range?

• A. 50-1000 V
• B. 50 volts or less; common examples include 48 V, 24 V, and 12 V
• C. 1000 V or less
• D. 7,000 V or more

Answer: (B)

Low voltage is defined by the level of electrical potential that minimizes shock risk, so many safety standards set the threshold at up to 50 volts. This matches the common voltages seen in equipment and controls, like 12 V, 24 V, and 48 V, which are widely used in telecom, data centers, and industrial systems. Options that extend into 1000 V or higher would fall into higher voltage classes with much greater hazard and stricter safety requirements, while a limit above 50 V would not align with the typical low‑voltage category. So the best answer is the range of up to 50 volts, with 12, 24, and 48 V as representative examples.
