Web a safe approach distance is the minimum separation in air from an energised overhead electric line that should be maintained by a machine, person, or object held by or in contact with that person. Over 1,000 kv, the utility/owner or a registered engineer must establish it. Nfpa 70e table 130.4 (c) (a) * for nominal voltages not listed use the next higher voltage in the table.

The Following Table Provides Minimum Approach Distances Grouped By Nominal Voltages.

Web osha refers to mad as “the closest distance a qualified employee may approach an energized conductor or object.” osha mad requirements in 2014, osha updated the 29 cfr 1910.269 and 1926 subpart v standards with requirements for all employers to establish mads. 345 kv is 4.93 p.u. The approach distance for each work zone (see figures 3 and 4) will vary depending on the voltage of the overhead electric line and the level of authorisation of each person carrying out the work. Over 750v not over 2 kv:
