What is the FPB distance for voltages in the 30 to 700 V range?

Explanation:
FPB distance defines the fixed safe boundary around exposed energized parts that workers must respect to limit shock and arc-flash exposure. For voltages in the 30 to 700 V range, four feet provides an appropriate buffer—long enough to reduce the chance of contact or dangerous arc effects, but not so large as to hinder routine tasks. As voltages rise beyond this range, the required FPB distance increases to maintain safety, which is why larger distances appear in other options.
