Gruber Power Services offers a comprehensive line of prefabricated data center power whips and
flexible PDU power cables for under-raised-floor installations. Our assemblies are built around
high-quality cable and NEMA plug configurations to feed cabinets, rows, and entire data halls. Weโve
supported power infrastructure in cloud, colocation, and enterprise facilities across the country, and we
hope youโll choose Gruber Power Services to supply your next build or expansion.
If youโre planning an under-floor power distribution system, our factory-built power whips are designed
to meet the demanding requirements of modern data centers. Running power under the raised floor optimizes space, enhances safety, and keeps power paths separate from critical network cabling. Gruber Power Services can build whips that align with any layout: hot/cold aisle containment, pod designs, or
traditional row-based architectures.
Under-floor power whips promote efficiency, cleanliness, and uptime. By routing power beneath the access floor, cabinets stay free of clutter, and power cords are kept organized, protected, and out of the way.
This reduces the risk of accidental disconnects, improves aisle safety, and simplifies moves/adds/changes as the data center evolves.
| Aspect | Field-Built On Site | Gruber Pre-Manufactured |
|---|---|---|
| Labor & cost | High, variable electrician time | Lower, fixed cost per whip |
| Quality & testing | Depends on crew & schedule | Factory-tested & labeled |
| Schedule risk | Whip fabrication can delay turn-up | Arrive ready to land and energize |
Having electricians build every whip on siteโpulling THHN, cutting conduit, landing every plug and receptacle by handโis expensive, slow, and error-prone during a construction project. Our pre-manufactured
NEMA power cables arrive on site cut to length, terminated, labeled, and factory-tested. Electricians can focus on main distribution equipment and inspections instead of repetitive cord fabrication.
Every facility is different, so we build whips to your specification. When you request a quote, please fill in the following parameters:
| Parameter | What to Specify | Example |
|---|---|---|
| NEMA outlet / plug type | Connector on the cabinet/PDU end (locking or straight-blade) | L5-30P, L6-30P, L21-30P, 5-20P, etc. |
| Voltage & amperage | System voltage, phase, and breaker size | 120V 20A, 208V 30A, 3ฯ 208/120V 30A, 480/277V 30A |
| Whip length (panel to cabinet) | Cable length from distribution panel or busway to cabinet | 25 ft, 40 ft, 75 ft (typical 10โ100 ft) |
| Pigtail length into PDU | Length of flexible tail from floor/entry point up into the PDU or cabinet | 6 ft, 8 ft, 10 ft (or per PDU height & routing) |
| Isolated ground outlets? | Specify if receptacles/whips require an isolated ground conductor | Yes (IG required) / No (standard grounding) |
| Additional notes | Any special jacketing, conduit, labeling, or phasing requirements | โRedundant A/B feeds, custom labels per row A1โA20โ |
Our engineers will confirm conductor size, jacket type, and configuration, then Gruber Power Services will
manufacture, test, label, and ship turnkey whips ready to drop under the floor and land in your cabinets.
Our inventory of PDU whips, panel cords, and related accessories includes everything you need to build a
robust, redundant power chainโfrom upstream distribution down to the rack. Under-floor power whips from Gruber Power Services help streamline power distribution, keep your white space tidy, and support the uptime expectations of todayโs data centers.
Designed with durability and serviceability in mind, our under-floor power solutions are ideal for cloud, colocation, enterprise, and edge data centers. If you have questions about selecting the right cables for your application, contact Gruber Power Services. Our team is happy to review your one-line, recommend plug types and lengths, and help you design a cost-effective, scalable under-floor power strategy.
