PDU-B Safety Label – 3" × 1.5" Black on Orange

Engraved label reading "PDU-B", 3" × 1.5", black text on an orange background. A "PDU-B" label identifies the second feed so the A and B sides are never mixed up.

For use on the B-side PDU cabinet, its output breaker panel and the racks it feeds.

Names a power distribution unit and tells the reader it is the B unit, usually the second feed paired with an A unit. It helps staff avoid dropping both feeds at once.

Where it's used: Typically on the front of the PDU cabinet, on its output breaker panel and at the racks or branch circuits it supplies.

• Wording: "PDU-B" (1 line, bold lettering)
• Size: 3" × 1.5" (76 × 38 mm), a small plate with room for two clear lines.
• Color: Black text on an orange background. Black on orange is commonly used for warning-level markings and stands out on grey equipment.
• Mounting: Peel-and-stick industrial adhesive back with no holes. Clean and dry the surface, then press it firmly in place.
• Material: 1/16" (1.6 mm) two-ply engraving plastic with a matte finish. The wording is engraved through the top color to the contrasting core, so it can't rub off like printed ink.
• Corners: Square-cut corners and clean edges.

Order it together with the A label and check both against the rack-level names so the pair reads consistently. Usually ordered by data center technicians and electrical contractors. Also called: PDU B label, power distribution unit B, B-side PDU tag.
