About this file
This document is a Material Specifications document for electrical cable, revised on 2/13/2025, issued by the South Carolina Department of Transportation (SCDOT). The specification details requirements for furnishing various types of electrical cables used in traffic signals, loop lead-ins, pedestrian signals, and pedestrian push buttons. The document describes multiple cable configurations, including black cables with 4, 8, and 12 conductors for traffic signal heads and pedestrian signal heads, as well as gray cables for loop lead-ins and pedestrian push buttons. Each cable type is specified with precise technical requirements including conductor size (#14 AWG), material composition, insulation characteristics, jacket specifications, and compliance standards.
The document outlines measurement and payment terms for these electrical cables, which are to be furnished in 1,000-foot reels and paid at contract unit prices for specific configurations such as "FURNISH NO. 14 COPPER WIRE, 4 CONDUCTOR - BLACK" and "FURNISH NO. 14 COPPER WIRE, 2 PAIR CONDUCTOR - GRAY". Vendors are required to provide catalog cuts for certification and furnish any manufacturer warranties as part of normal trade practice. The cables must meet stringent standards including Underwriters' Laboratories, SCDOT specifications, IMSA standards, ROHS compliance, Federal specifications, and National Electric Code requirements. The specification provides detailed technical parameters for cable construction, including conductor stranding, insulation thickness, jacket material, and dimensional tolerances.
