Minimum Approach Distance Chart
The minimum approach distance chart defines safe working distances to prevent arc flash injuries. Based on NFPA 70E and OSHA standards, it helps protect electrical workers by specifying limits by
Application Guide for 2023 NESC Table 232-1
Vertical clearance does not apply to neutral, comm, grounded guy, or TPX that are 10 feet or more from edge of pool, diving platform, slide, or pool objects. Aboveground pool with deck or ladder, clearance
Working Clearances, based on the 2020 NEC
And though this aspect is not covered by the NEC [90.1], good engineering requires consideration of what additional distance would improve efficiency for operation or maintenance.
Safe distance between buildings and power lines
There must be a minimum HORIZONTAL distance of 1.6 m between any part of a building and the closest low-voltage line. This applies to all configurations of low-voltage lines.
