What Is Overcurrent Protection Explained - The Electricity -- &#; An overcurrent situation is either an overload or a fault/short-circuit. The overload current is an excessive current flow relative to normal operating current, but still confined to the normal branch circuit paths provided by the conductors and equipmen. A fault (often referred to as a short-circuit) flows outside the normal circuit paths.
What Is Overcurrent?(Causes, Effects and Protection)Overcurrent protection devices (OCPD) are items of equipment employed in electrical systems that are susceptible to experiencing an overcurrent due to short circuits, overloads or ground faults. Today, many homes are equipped with circuit breakers situated in the primary service panel, also known as a “breaker box.”.
