Minimum Approach Distance Chart
OSHA 29 CFR 1910.333 (c) (3) requires a minimum distance of 10 feet (3.05 m) from overhead lines under 50 kV, and an additional 4 inches for every 10 kV over 50 kV.
Cable Separation Guide: Telecom & Power Cables | Safety & EMI
Technical guide for safe separation of telecommunication and power cables. Covers aerial, buried, and building installations. Includes OSHA, NESC, ANSI/TIA/EIA standards.
Safety distance of overhead conductor
The safety distance between the conductor phase and phase, phase and ground and other objects of the overhead line is determined by the voltage level, pole type, span and field installation conditions
10KV-35KV Overhead Cable Planning and Design Issues
