The minimum approach distance for voltages between 50 and 750V is ___.

The minimum approach distance for voltages between 50 and 750V is 10 feet. This distance is established for safety measures to protect individuals from electrical shock hazards. It is important to maintain this distance when working with or around energized equipment and overhead lines to ensure that workers do not inadvertently come into contact with live electrical components.

This standard is based on the principles of electrical safety, which dictate that the closer an individual is to a source of electrical potential, the higher the risk of electric shock. Maintaining a minimum distance helps to mitigate this risk, ensuring that workers can safely perform their tasks without exposing themselves to dangerous conditions.

In the context of electrical work in HVACR and other related fields, adhering to these safety regulations is critical for protecting both workers and bystanders from potential harm.
