Continuity testing is primarily associated with which component?

Continuity testing is primarily associated with traffic signal conductors because it is a method used to verify that electrical connections are intact throughout the length of the conductor. This process helps ensure that the signals are transmitted effectively without any breaks or faults, which can lead to malfunctioning or unreliable performance of traffic signals. By conducting continuity tests, technicians can confirm that the circuit is complete and that electricity can flow freely, thereby supporting the proper operation of the signal system. Engaging in this testing is essential for maintenance and troubleshooting within traffic control systems.
