What does ADS stand for in electrical safety?

• A. Automatic disconnection of supply
• B. Automatic disconnect switch
• C. Automatic disposal system
• D. Automatic device shutdown

Answer: (A)

In electrical safety, ADS means Automatic Disconnection of Supply. It refers to the protective measure that automatically cuts off the electrical supply when a fault, overload, or unsafe condition is detected, helping prevent electric shock and reduce fire risk. This is achieved with protective devices like fuses or circuit breakers that trip or open automatically to interrupt current quickly. The other options describe a device or concept that isn’t specifically about automatically removing the supply power, so they don’t fit the established safety terminology.
