Which term is used for a load that operates under constant conditions for an indefinite time?

• A. Cyclic Load
• B. Continuous Duty
• C. Surge Load
• D. Peak Load

Answer: (B)

The term "Continuous Duty" refers to a load that operates under constant conditions for an indefinite time. This implies that the load is designed to run continuously without interruption and is expected to perform its function over an extended period, often defined in hours, days, or even indefinitely, as long as it is supplied with power. For appliances and electrical systems, understanding the concept of continuous duty is critical because it affects the selection of equipment, the sizing of electrical circuits, and the overall design of mechanical and electrical systems. Appliances such as refrigerators, air conditioning units, or any electric motor that is meant to run continuously are often classified under this term, which allows for reliable performance and efficiency. Cyclic loads, in contrast, refer to operations that repeat at regular intervals, increasing the wear on components due to repeated start-stop cycles. Surge loads are characterized by short bursts of energy consumption that occur when a device starts up, whereas peak loads are the maximum power demand during a specific period. Therefore, the term Continuous Duty appropriately encapsulates the persistent and stable nature of the load being described.
