Definitions:

Overcurrent

A condition where the current exceeds the maximum allowable current for a circuit or device, potentially leading to damage or operation failure.

Overload Conditions

Situations where electrical or mechanical systems are subjected to a load greater than their design capacity, potentially causing damage or failure.

Electrical Current

The flow of electric charge through a conductor, typically measured in amperes, fundamental to the operation of electrical devices and circuits.

Short-Circuits

Short-circuits occur when an unintended electrical connection allows current to flow along a low-resistance path, potentially causing damage or a hazardous situation.
