Installing Bus Ducts Properly

Bust ducts, known also as busways, are created from a sheet of metal with the busbar being made of copper or aluminum. Bus ducts conduct electrical currents, that is their main purpose when used in manufacturing.  Many companies manufacture bus ducts, with the most popular supplier being Square D.  Not only does Square D manufacture bus ducts, they supply a wide range of bus plugs, electrical switches, circuit breakers, and more.  Proper installation and assembly of a bus duct will save you money and prevent costly downtime. 

Proper Bus Duct Installation

In order to ensure your electrical system functions properly your bus ducts must be installed correctly.  Bus ducts are used to provide power throughout an electrical system so if there is an issue with the bus duct it can result in costly delays and downtime.  In order to avoid this, proper installation is required.

The Importance of Ampacity

The amount of electrical current that a device can withstand without being damaged is known as ampacity.  A bus ducts ampacity rating is determined by using the temperature within the operating space and referencing a standard chart for temperature assumptions.  Once the operating temperature has been determined users must consider the rise in temperature between a zero current and a full load current.  As an example, a common bus duct with copper inside often has a current rating of 2,000 amps per square inch.  The rating results in the voltage dropping as the temperature increases.

Additional Protection

Like with any installation especially electrical, location is a key aspect that needs to be considered.  For most facilities bus duct installation is downstream from transformers and upstream from the primary overcurrent device.  Whatever devices is being used to protect the transformer cannot be used to protect the bus duct from electrical fault.

Extra protection to the bus ducts is another way to decrease any potential downtime from occurring.  When downtime occurs, facilities end up paying for workers to stand around.  Adding an extra layer of protection to your bus duct will give you extra peace of mind as you will know your bus duct will properly function.   

Bus ducts that are installed outdoors should include protection from the elements.  Choose a shelter that allows water to drain vs sitting in a pool overhead.  Extra water allowed to collect can cause a short in the bus duct.  Humidity can also be an issue when bus ducts are utilized outside.  This can be prevented by using stainless steel as it inhibits corrosion.  An epoxy primer of paint can be added to the housing to prevent the oxidation of the metal.

Bus ducts can also be installed on an outside wall.  When this is the case proper flame-retardant wall fittings that are waterproof and vapor-resistant should also be used as a precaution.  Extra supports for the ducts where they enter the wall should be in place to hold the extra weight. 

The installation of bus ducts is important.  Correct installation allows a system to function properly without downtime.  Protection helps to prevent corrosion and protects from outside elements.  And using proper metals and assembly kits from the manufacturer help to ensure you are using the right materials for your bus duct assembly.

Introducing World’s First Digital Circuit Breaker

Technology continues to change the world that we all live in and that doesn’t stop when talking about the electrical world as well. The world’s first and only digital circuit breaker certified for commercial use has been introduced by the company Atom Power. This new breakthrough will not only make power easier to manage but also 3000 times faster compared the fastest mechanical breaker. Atom Power continues research to accomplish more successes in the field and is ready to take on more challenges with investments from three of the four largest circuit breaker manufacturers, Siemens, ABB, and Eaton to shape the future of electrical power. To understand how this new digital circuit breaker fully works, check out the article “How the World’s First Digital Circuit Breaker Could Completely Change Our Powered World”.

Diagnosis Is A Key Element In The Process of Reconditioning

Electrical components are quite complicated in their nature.  There are dozens of moving pieces, working together to create a working electrical device from computers to panel switches, transformers and bus ducts, electrical products are intricate in nature.

It is important with any electronic device that we are able to find and replace components that have failed.  When a component fails on multiple levels, product reconditioning verse repair may be inevitable.  Of course, this varies from product to product, but the one common element is that when faulty diagnostics need to be performed.  In the latest installment from Radio World, “Making Sense of Component-Level Troubleshooting” individuals can learn what is involved in digging inside electrical components to diagnosis what is going on. 

Here at J and P Electrical Company we specialize in the sale of new and refurbished electrical components used in manufacturing and industrial settings.  We also offer services in asset recovery and management where we go in and remove electrical components in an attempt to clean industrial plants out of reusable items.
