What Is Whip Drop?_
In data-center power distribution, a whip drop provides the final, flexible connection from the overhead busway tap box or a floor-mounted PDU to the rack's power inlet. It typically consists of a factory-terminated cable with a connector that mates to the busway tap and a connector that plugs into the rack's PDU or receptacle. Whip drops allow for quick rack moves and adjustments without re-running rigid conduit.
Technical Details
Whip drops are usually pre-terminated with industry-standard connectors such as IEC 60309 or NEMA, and are available in lengths commonly ranging from 10 to 20 feet and ampacities from 30 to 60 amps. The cable is typically stranded copper with a flexible jacket (e.g., SOOW or SJOOW) to withstand repeated bending. In typical deployments, whip drops are routed from overhead busway to each rack's power distribution panel, following the structured cable tray path to avoid interference with liquid cooling hoses.
How Leviathan Systems Works with Whip Drop
During rack assembly, field crews install whip drops from the overhead busway tap to each rack's PDU, ensuring proper strain relief and labeling per the site's power plan. Whip drops are often the last power connection made before commissioning, as they allow final rack positioning.
