What is the Limited Approach Boundary for fixed exposed and potentially energized conductors?

Explanation:
The Limited Approach Boundary represents the distance from fixed exposed and energized conductors within which a shock or arc-flash hazard exists if someone moves closer without proper protection. For this specific scenario, four feet is the standard distance used to designate that boundary. It’s the point at which you must start using additional safeguards—like insulating barriers, qualified personnel, and appropriate arc-rated PPE—because the risk of electric shock or arc energy increases if you go closer. Keeping outside this boundary minimizes exposure, while entering it triggers mandatory protective measures and recognized safety procedures.
