THE BLUEPRINT

Reliability , flexibility and safety :

The three essential qualities you should look for in a track busway power distribution system

Introduction
For data centre owners and Consulting and Specification Engineers ( CSEs ), busway systems are rapidly becoming the solution of choice for effective power distribution . Busways can be suspended from the ceiling , placed on vertical supports or even mounted on the server cabinets themselves to provide a direct power source to servers and racks .
Busway systems offer numerous advantages over traditional Remote Power Panels ( RPPs ). Suspended or mounted track busways eliminate the need for an RPP , allowing you to make better use of data centre space . Busways also eliminate the need to run power cables and whips under plenums in a raised floor , allowing cooling air from below to flow unobstructed to the servers . If inrow cooling units are used along with busways , it eliminates the need for the raised floor itself .
A busway system gives you full visibility over your power distribution system , making it easier to do maintenance and troubleshooting . Unlike RPPs , electricians don ’ t have to shut down the entire system or do hazardous work on a live and exposed panel , in order to change out a single circuit breaker .
Using plug-in units ( a . k . a . tap-off boxes ), which are inserted into the busway ’ s open channel and connected to the internal busbars , you can easily and safely swap out old circuits and replace them with new ones in a matter of minutes .
But not all busway solutions are the same ; some busway systems work better , last longer and require less maintenance than others . In evaluating a busway solution , you should look for three important qualities :
• Reliability – An effective busway system provides reliable and efficient power distribution , a maintenance-free joint design and a long useful life , to ensure continuous uptime for your IT infrastructure .
• Flexibility – An effective busway system gives you flexible design and power distribution options , allowing you to build out , scale up and adapt your IT loads according to your changing power and facility needs .
• Safety – The elements of a busway system should guarantee safety for your workers , your IT infrastructure , and your facility .
In this white paper , we will examine these three qualities in detail , and apply them to the individual elements of a track busway system .
NOTE : Although this white paper focuses on data centre facilities , many other types of facilities such as assembly plants , manufacturing and distribution centres , laboratories , retail stores , etc ., can also benefit from using a busway system for power distribution . This report will tell you what qualities you should look for in a busway solution , no matter what your industry . �
