When a conductor carries a current beyond its carrying capacity, the temperature of the conductor increases. As the temperature increases, the resistance of the conductor also increases, which results in a decrease in the carrying capability of the current. If the conductor continues to carry a current beyond its new carrying capacity, the temperature of …
The current-carrying capacity of a conductor refers to the maximum rated current that a conductor can handle under specific operating conditions. The current carried by a conductor is actually an electric load generated by the motion of electrons through the conductor. The current-carrying capacity of a conductor directly affects the load capacity and electrical safety …
