How must spare signal conductors inside the cabinet be arranged?

• A. Left hanging in the controller
• B. Connected to an unused terminal
• C. Connected to ground rod
• D. Connected to the neutral buss

Answer: (B)

Arranging spare signal conductors inside the cabinet by connecting them to an unused terminal is important for several reasons. First, this method helps maintain organization within the cabinet, preventing loose or unconnected wires, which could lead to confusion during maintenance or system modifications. Properly terminating these conductors reduces the risk of electrical shorts or interference with active circuits, enhancing safety and functionality. Leaving the conductors hanging can create hazards, as exposed wires can potentially come into contact with other components, leading to unintended signals or electrical hazards. Connecting to a ground rod or neutral bus does not directly serve as a proper termination for spare conductors, as these options are generally intended for power and grounding connections, not for signal termination. By connecting the spare conductors to an unused terminal, you create a clear indication that these conductors are available for future use while ensuring that they are safely managed within the system cabinet. This approach enhances both the reliability and safety of the traffic signal system.
