In a wiring diagram, "NC" stands for "Normally Closed." This indicates a switch or relay contact that is closed (allowing current to flow) when it is in its default state, meaning it will only open when actuated or triggered. It is often used in applications where a circuit needs to be completed until a specific condition occurs. Understanding NC is crucial for correctly interpreting the function of a circuit in various electrical systems.
