Which statement best defines overload current?

• A. A current that is in excess of normal current but confined to normal conducting paths.
• B. A current that is in excess of normal current but not confined to normal conducting paths.
• C. The maximum circuit voltage of a fuse.
• D. The current that the fuse is intended to normally carry.

Answer: (A)

Overload current is a current higher than what the system is designed to carry, yet it stays in the normal conducting paths of the circuit. This means the current exceeds the normal operating level but is still flowing through the usual wires and components, not through an abnormal path. The option describing this exact situation matches the idea of overload. If the current moved outside the normal conducting paths, that would point to a fault such as a short or ground fault, not just an overload. The other statements refer to voltage rating of a fuse or to its normal operating current, neither of which define overload current.
