How far should a distribution box be from power lines

The OSHA 10-Foot Rule mandates that workers, tools, and equipment must stay at least 10 feet away from overhead power lines carrying up to 50 kV (kilovolts) of electricity. For power lines carrying higher voltages, the minimum safe distance must increase by 4 inches for every additional 10 kV. In the Health, Safety, and Environment (HSE) domain, adhering to these guidelines is crucial to mitigate risks. The employer determines that it is infeasible to do the work without breaching the minimum approach distance under Table A of § 1926. It takes the incoming power and safely distributes it to different circuits throughout your building.
