Electric Utility (Red) – Marks buried electrical cables and power infrastructure. Keeping track of what's exactly buried underground on a worksite can be a challenge, which is why utility locators follow the uniform color codes mandated by the American Public Works Association (APWA) for temporarily marking their facilities. The American Standards Institute (ANSI) established. The “Xcel Energy Standard for Electric Installation and Use” contains the requirements and uniform standards necessary to achieve this policy. Uniform enforcement of these standards throughout the Company will expedite service connections and treat each of our customers equally and fairly. If the conduit size is not given on the drawings, the conduit shall be sized in accordance with NEC based on the number of conductors enclosed plus a parity-sized. Provide labels, nameplates, panel directories and color-coding as specified herein and according to attached electrical identification drawings. Surface marks on roadways do not exceed 1. 5" y 18" (40 mm by 450 mm). The facility color and facility owner identity may be added of-service buried lines.
