Engraved label reading "WARNING / ARC-RATED PPE REQUIRED / MIN ARC RATING: ___ cal/cm² / WITHIN ARC FLASH BOUNDARY", 4" × 2", white text on a black background. A "MIN ARC RATING" label puts the protective gear requirement right on the equipment.

For use on the front of switchgear, panelboards and MCCs to post the arc-rated gear and minimum rating for that equipment.

This label warns that anyone inside the marked boundary must wear arc-rated protective gear, and it leaves a blank for the minimum arc rating. It tells a worker what to put on before going closer.

Where it's used: Switchgear, panelboards, motor control centers and disconnects, usually on the front door or cover facing the person approaching.

• Wording: "WARNING / ARC-RATED PPE REQUIRED / MIN ARC RATING: ___ cal/cm² / WITHIN ARC FLASH BOUNDARY" (4 lines, bold lettering)
• Size: 4" × 2" (102 × 51 mm), the most popular size for equipment, panel and door labels.
