Which of the following terms describes a load exceeding its duration limitation set by electrical codes?

Overload
Short circuit
Reserved load
Continuous load

The correct answer is: Overload

The term that describes a load exceeding its duration limitation as set by electrical codes is overload. In electrical systems, an overload occurs when the current flowing through a particular circuit exceeds the rated capacity of that circuit, leading to potential overheating and damage. Electrical codes, such as the National Electrical Code (NEC), establish specific parameters for safe operation, including how long a circuit can handle a particular load continuously. When a load operates beyond these specified limits, it can cause significant issues such as tripped breakers, blown fuses, or even electrical fires. By adhering to these code limitations, one can ensure that electrical systems operate safely, and understanding the concept of overload is crucial for anyone involved in electrical design and maintenance. This not only helps in preventing equipment damage but also promotes overall safety in electrical installations.
