S-974-TRAFFIC-SIGNAL-AND-MULTIPLE-STREET-LIGHT-CONDUCTORS-600-VOLTS-PVC-COPPER.pdf

This is a City of Pasadena Public Works & Transportation Department standard technical specification document (Standard Plan S-974) detailing technical requirements for traffic signal and multiple street light conductors rated at 1600 volts PVC copper. The document provides comprehensive specifications for conductor types, sizes, insulation colors, and usage across various electrical systems including vehicle signals, pedestrian signals, push buttons, and street light circuits. The specification covers conductor gauge sizes from #14 to #2 AWG, with specific requirements for conductor insulation thickness, strand composition, and color coding for different signal and electrical system applications.

The technical specification includes detailed tables defining conductor characteristics such as signal phase functions, insulation base and stripe colors, band symbols, and conductor sizes for different electrical circuit types. Notable technical details include color-coded traffic signal conductors, specific requirements for vehicle signals (phases 2, 4, 1, 5, 3, 7), pedestrian signals, and street light circuits. The document provides guidance on conductor placement, including band conductors in pull boxes and near termination points, with specific notes indicating variations from standard Caltrans specifications. The document is revision 2, dated 5/7/02, and was prepared by Bang Chau, checked by Cathy Chang, and approved by the Acting City Engineer.
