what N.C. mean in diagram alarm
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.
"Mean no NC relay" typically refers to the absence of a normally closed (NC) relay in a circuit or system. In relay terminology, a normally closed relay allows current to pass through when the relay is not energized, whereas a normally open (NO) relay does not conduct until it is activated. Thus, "mean no NC relay" suggests that the system only uses normally open relays, which can impact how the circuit operates, particularly in controlling devices or signals.
The alarm contact for a Molded Case Circuit Breaker (MCCB) is a feature that provides a signal or indication when the circuit breaker operates, typically due to overload, short circuit, or other fault conditions. This contact can be connected to an external alarm system to alert operators or maintenance personnel about the status of the circuit protection. Alarm contacts are usually configured as normally open (NO) or normally closed (NC) and can be integrated into control systems for monitoring purposes.

nc means "not connected"
NC on a schematics typically stands for "No Connection" meaning that nothing is to be connected to that node.
no comment i think
Yes, if the warrant is on file in the National Crime Information Computer system and NC states that will extradite.

Yes it is

Yes. Since points are added based on speed and type of violation, and not the location of the violation. The points are based off NC system, though, not VA system.
