(B) Clearance From Ground
- 2.9 m (91/2 ft) — above finished grade, sidewalks, or from any platform or projection from which they might be reached and accessible to pedestrians only
- 3.5 m (111/2 ft) — over residential property and driveways, and those commercial areas not subject to truck traffic
- 4.7 m (151/2 ft) — over public streets, alleys, roads, parking areas subject to truck traffic, driveways on other than residential property, and other land traversed by vehicles such as cultivated, grazing, forest, and orchard
Informational Note: These clearances have been specifically chosen to correlate with ANSI/IEEE C2-2012, National Electrical Safety Code, Table 232-1, which provides for clearances of wires, conductors, and cables above ground and roadways, rather than using the clearances referenced in 225.18. Because Article 805 and Article 820 have had no required clearances, the communications industry has used the clearances from the NESC for their installed cable plant.
