Underfloor Power Solutions

Underfloor Power Solutions

Raised floors are still the standard in the data center industry, with power cables running underfloor and data or network cables running overhead.  Because it's the most common data center configuration does that make it right for your data center?  That's hard to say, it is a personal choice with a lot of pros and cons to be considered that should be based on thoughtful consideration.  

 

PDU Cables branch circuit power distribution cables are being installed every day, below a raised floor and overhead with ladder racks and in a cable tray.  

 

To accommodate underfloor power cabling, PDU Cables, offers liquid tight flexible metal conduit (Liquid Tight) in eleven colors as the best choice for underfloor cabling.  You also have your choice of different weather proof receptacle bell boxes, and a broad selection of mounting hardware designed to elevate the receptacles up off the floor and within easy reach of a pulled floor tile.  

 

Cable Types

Liquid Tight Flexible Metal Conduit (LFMC)

Flexible Metal Conduit - (RWS & RWA) - Field Wires

Metal Clad Cables (MC Cables)

SO Cords - Molded Cord Assemblies

Tray Cable - STOOW

 

Device Types

The NEMA (National Electrical Manufacturers Association) pattern and numbering system is made up of four main identifiers. The first identifier can be a blank space or have the letter L. This determines whether it is a straight or locking blade device. The second identifier is a number. The first number in a NEMA listing determines the voltage rating. The third identifier is a number and identifies the amperage rating of the device. The fourth identifier is a letter. This identifier determines whether the device is a plug, P, or a receptacle/outlet, R.
