Overview
Credit: 5 PDH
Length: 31 pages
This five hour course will discuss the requirements for the installation of different types of traffic cables, conduits, and junction boxes used in the installation of a traffic signal. State and local governmental jurisdictions have their own requirements for the type, placement, and size of traffic signal cables, conduits, and junctions boxes, as set forth in the various standards promulgated by the Departments of Transportation in different States.
The installation of a traffic signal requires that the signal cables (wires) be connected between the Controller Cabinet and junction boxes through underground conduits, which are also know as splice boxes or pull boxes. The underground conduit system has to connect all the traffic signal poles, so that each traffic signal device can be powered and controlled by the traffic controller.
