What safety feature is associated with operating irrigation valves at 24 volts?

• A. It will not injure people if a buried wire is cut
• B. It improves performance
• C. It reduces energy consumption
• D. It shortens installation time

Answer: (A)

Low-voltage control circuits are used to keep people safe when underground wiring is damaged. With irrigation valves operating at 24 volts, a cut or exposed buried wire presents a much smaller shock risk because the voltage is low and current is limited by the power source. This design typically uses a transformer to step down from higher mains voltage to 24 volts AC, so even if a wire is accidentally touched, the chance of a serious electrical shock is minimal. The other statements don’t describe a safety feature: 24 volts doesn’t inherently boost performance, significantly cut energy use, or shorten installation time.
