ASHRAE releases expanded, revised version of Standard 90.1

Standard 90.1 has been a dominating benchmark for energy codes in the commercial building space since 1975, but recently a large update to this benchmark has been released that brings about important changes for all relevant industries to be aware of. ASHRAE released a revised and much-expanded version in and for 2019 and includes changes regarding lighting, mechanical, budget method, and performance rating methods, to name a few. On the mechanical side, for one example, the revised version allows designers the option to use 90.4 instead of 90.1 for rooms with IT equipment load larger than 10kW.

It is highly encouraged for all professionals in relevant industries to be familiar with this expanded and revised version of a Standard that has such a wide footprint over many different industries.

The Importance of Preventative Maintenance of Bus Ducts


Having an uninterrupted supply of electricity for customers is the main goal of a power generation industry to allow them to meet their demands. It can be very costly for a company to have any unplanned downtime due to any equipment failures. This is a fact when looking at bus duct systems since they effectively transfer power to switchgear and other loads. To prevent avoidable downtimes from occurring it is imperative to have preventative bus duct maintenance in place.

Neglect on Systems

Too often, critical systems like bus ducts that transmit power at industrial buildings go neglected. The reason behind this is because people are under the wrong concept that since bus duct systems do not consist of moving internal parts that they do not need regular maintenance or service. Over time, carbon and other foreign debris can build up and contaminate the bus systems that will, in turn, cause cataclysmic arcs and damage the equipment. Without proper inspection and preventative maintenance performed regularly, the equipment will have without a doubt have unexpected failures that will cause outages, can further damage equipment and increase safety risks for personnel as well. 

Preventing Failures

It is very important to have regular and systematic inspections of the bus duct systems performed. If the installation is done in unfavorable conditions, for example, high temperature/ humidity or environments with a lot of dust it is recommended these inspections are performed at a more frequent interval in these instances. The most common failures that are observed during bus duct failures can range from damaged gaskets/ bellows, grounding issues, cracked weld joints, conductor connection integrity, and even improper termination design or installation.

Installing New Bus Ducts

One factor to consider when installing a new or replacing bus duct system is to consider the ampacity requirement for your actual operating environment as opposed to just choosing one based on a standard chart’s temperature assumption. The most bus generally occupies at high-temperature areas since they are installed near the ceiling. Temperatures will continue to fluctuate while under load or no load as well, so it is important to do the research and know the limits of the equipment. Another good piece of advice is to install extra protection with service conductor bus ducts to protect the bus duct zone from fault. It may be an extra up-front cost but the savings from downtime in the future will be well worth it.

Why is Asset Recovery Important?


Electrical plants can house a plethora of dangerous components and parts, and when one is torn down, for whatever reason, often what is left behind can be troubling for more than one party. Asset recovery is a very important step in this process and is something one should consider when dealing with large-scale tear-down projects. Fortunately, many organizations exist with fully insured, experienced, and professional experts who specialize in the proper recovery of assets of all kinds. Regardless, there are a few reasons to keep in mind as to why asset recovery is important.

Bad material in planet

 Electrical components may sometimes be made from natural resources, but the vast majority are man-made objects and thus do not do the planet any favors when left behind on tear-down sites. The material used to make these objects need to be recovered by a company that specializes in asset recovery so these materials can be stripped down and either recycled properly or reformatted to fit within new products. If this does not happen you can see these objects sticking around far longer than the planet would like, which benefits nobody.

Liabilities and cost

The cost of electrical components and parts can vary from relatively cheap to astonishingly high prices, depending on the nature of the item. It’s obvious that companies want to make money, so the idea of leaving assets and potential dollars on sites is not business owners. Being able to recover these assets ends up saving the supplier or manufacturer thousands of dollars AND prevents the assets from causing harm to the enviroment.

These components or IT assets can be a liability if not properly recovered and/or recycled. For certain IT components and devices, the possibility of sensitive information can always remain despite any attempts of wiping data, and anybody can recover these assets not affiliated with any professional asset recovery organization and use that data to their own advantage. It’s important that proper recovery is completed to not leave any potential data leaks from happening onsite.

Stolen

An obvious reason in which asset recovery is important bleeds into the prior two reasons: stolen property. Because a wide variety of electrical and IT components and parts are very expensive to the manufacturer no business wants to waste the money having their equipment stolen by somebody before it can be properly recovered. Theft is a widespread and universal issue spanning all industries and the theft of electrical components is not spared. It is an ongoing issue with theft and that is a good reason to support the recovery of electrical assets.

Understanding Bus Plugs

If you are not an electrician or familiar with the terms used in the electric power fields, the products that make our homes and business run efficiently may be very mysterious. For some people, a bug plug sounds like its something the belongs in the automotive industry for actual busses? We are here today to get your electrical knowledge straightened out and give a inside look to what a bus plug really is and what it does.

What Is It exactly?

Bus plugs are basically what the name entails and are large industrial electric plugs that are like the ones you find in homes. However, Industrial or manufacturing plants that utilize heavy machinery require specialized power needs that is unique when compared to typical power distribution systems that are used inside residential or commercial buildings. Each bus plug is designed to connect to a specific section of bus duct or also known as busway, overhead and will then transfer electricity down to any chosen product whether it’s a lighting system or heavy equipment that needs power below. Busways were first produced in the late 1920’s for the automotive industry in Detroit and have since continued to improve and make their ways into many industrial plants to be utilized.

Why use them?

When looking at many industrial plants or buildings, many are structured in design with large open floor plans to maximize the total square footage and allow a variety of uses for the specific area. One of the major benefits of the busway and bus plug system is the flexibility of each product. With this type of installation, there is no physical hard wiring and the whole electrical system can be removed and rearranged to accommodate the building floor plan needed. As the future continues to change the machinery used, there are no concerns as to how power will be given to new equipment when things need to be moved or upgraded. Bus duct systems are a very efficient solution to get a lot of power to a big area that power distribution continues to change frequently. This is another reason why manufacturing plants need these products in order to provide large quantity of power to different areas of the building.

Proper Maintenance

Unplanned downtime can be detrimental and costly to any business and can be avoided with proper maintenance and service on products when needed. Bus ducts are extremely important in effectively providing power to switchgear and other different loads. Unfortunately, it is typical to find that critical systems that transmit power for industrial facilities are often neglected since many of people are unaware that regular maintenance and service is required even though bus ducts do not utilize moving internal parts.

Questions That Are Important to Ask When Buying Electrical Surplus Inventory Online


When a project is cancelled, warehouses are liquidated, or there are manufacturing overruns an electrical surplus inventory is generated.  Local surplus dealers were once the only sellers of electrical surplus inventory.  Today however, surplus equipment can be purchased through e-commerce platforms.  It is important you should proceed with caution when you come across surplus electrical component’s suppliers online; research and asking the right questions when buying online is crucial.  Below you will see how you should proceed when buying electrical surplus online.

Asking the right questions when buying surplus electrical equipment online helps you make the right purchase.  These questions should include:

  • Is the equipment a product that is from the original factory?
  • Will the new surplus inventory come in a sealed box?
  • Are there any visible structural damage like fractures or cracks in the equipment?
  • Do the products being sold contain any proof of safety and reliability?
  • Are there any signs of the equipment being burned in any way?
  • Has the equipment been in use, when?
  • Has the product failed?  What were the circumstances of the failure?
  • Do the products come with a warranty? When does the warranty expire?
  • Does the equipment have a period in which it can be returned if it does not meet the required standards?

Essentials to Consider When Purchasing Surplus Electrical Equipment

Voltage Ratings Input/Output

Know the voltage rating of the surplus electrical product as well as the voltage rating of your power sources.  This will determine if the equipment is suitable for your application.  Incorrect voltage ratings risk short circuiting, arching, and electrical fires.

Continuous Current Rating

The continuous current rating will allow you to know if the device will be able to perform properly in varying environments.  This is listed as Amperes.  They represent the continuous current that can be carried when used in the temperatures it is calibrated for.

Current Rating, Short-Circuit

Short-circuit current rating, SCCR, is a current rating that defines the maximum short-circuit current the product can safely handle.  Individual SCCR components for the electrical assembly are calculated to determine the SSCR for the entire electrical panel.

Electrical Current Frequency

Pay attention to the current frequency at which equipment or breakers are designed to operate properly.  The electrical current frequency determines the highest current a device can handle operating at without issue.

Don’t compromise the quality of surplus equipment by purchasing from a less than a reputable electrical component supplier.  At J & P Electrical, we assure quality and competitive pricing.  Contact us today to discuss your needs.

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.

Choosing Circuit Breakers Over Fuses

In the past fuses were the only option when it came to protecting homes, businesses, and equipment against overloaded circuits, shorts in circuits, and other faults.  With advancements in technology, circuit breakers became a popular option over the use of fuses due to the number of advantages they are able to offer.  The use of modern-day circuit breakers creates increased safety and reliability, decreased costs, and additional support for energy management initiatives.

Benefits of Using Circuit Breakers

Performance Reliability

The performance of fuses can decrease overtime.  Age increases the instances of fault, causing fuses to open even under normal conditions.  There is no way for fuses to be tested thus the current value that causes it to become faulty can never be determined.  Circuit breakers however are tested when manufactured and can be tested throughout its lifetime to ensure peak performance.

Comprehensive Protection

Circuit breakers trip circuit, breaking the electrical connection, up to a thousand times faster than fuses.  The trip capacity of a circuit breaker is greater than the equivalent fuses.  Modern day circuit breakers provide exception fault current limitations which was once only known to occur with fuses.  This function offers reliable protection while increasing the life of equipment by decreasing the aging that occurs with frequently tripped circuits.  Unlike fuses that can experience an overload even when one of multiple fuses opens, this will never occur within a circuit breaker.  When one breaker experiences an overload, the connection will be stopped immediately.

Increased Safety and Production

Replacing fuses can be risky for untrained personnel.  Fuses have exposed conductors and therefore can be quite tricky to change out.  The connections for circuit breakers are hidden, being that it is unexposed it keeps re-connecting the circuit safer for employees.  A major cause of fires within industrial settings occurs because of fuses that were incorrectly replaced.  This could include using the wrong fuse, incorrect model and/or rating, and more.   These issues are almost inconceivable when correcting a tripped connection when using a circuit breaker. The time saved is also considerable when using circuit breakers as reclosing the breaker can occur instantly which prevents production downtime.

Savings

Although the cost of a single fuse is less than the cost of a circuit breaker overall the installation and usage is less expensive.  Consider that three-phrase circuits must have three fuses.  Also, the cost of keeping extra fuses in stock.  Overall operation costs of using fuses instead of a circuit breaker are higher.

More Functionality

Circuit breakers, unlike fuses, can offer additional functions like ground fault protection.  System coordination between breakers, cascading and selectivity cannot occur when using fuses whereas circuit breakers allow for this feature.  Newer technology allows for circuit breakers to use remote controls, have alarm features, offer measurement features, and communication within your network.

The Basics in Wiring Electrical Disconnect Switches

Understanding how the electrical system works in your manufacturing facility is not as difficult as you may think. While it may seem like magic how the lights turn on or how the power gets to your stuff that you plug into the wall outlet. However, it is far from magical and in fact it is quite simple really. It is not a very complex system when explained.

 

There are several parts that make up your electrical service, one of the most important parts being the disconnect switch. This device is designed to instantly shut off the power to your facilities main power panel. This device is a very important part of your manufacturing electrical system and should only be used in extreme conditions.

 

How does an electrical disconnect switch work?

The basic operation of an electrical disconnect switch is simple in that it truly has only one purpose and that is to kill the power to the main power panel for your facility. All the facilities wiring goes into the main power panel and is connected to breakers that control the power inside the building. The disconnect switch sits in line between your facilities electrical meter and main power panel.

 

By turning this switch off you will instantly disconnect all power going into your location, this does not however, have any effect on your electrical service. You will continue to have power at the meter and on the feeder side of disconnect switch.  It is important to know where your electrical disconnect switch is, which is also referred to as the electrical service disconnect switch.

 

When repairs or replacement is needed it is important to find the right parts.

Due to the seriousness of the functionality of the electrical disconnect switch only trained professionals should ever open up the disconnect switch box. This is because the feeder lines going into the switch have 240v running through them and that is enough to kill a person if you are in direct contact with it. When repairs are needed, and it becomes necessary to replace the electrical disconnect switch there are several options that will be recommended.  One of the more common options in manufacturing is budget friendly reconditioned disconnect options.

 

When parts are needed you can insist on using reconditioned equipment.  Often reconditioned electrical components like the disconnect are preferred as they not only save you money but most often all the bugs that are found in new OEM parts have been worked out and fixed.

How Reconditioned Electrical Components Can Save Manufactures Money

If you are a manufacturer of products you know how essential it is for you to keep those operating costs down to make as much profit as possible and to see your business thrive.  One way of reducing your overhead is by purchasing those raw materials at the least expensive rates possible.

Another way of reducing those operational costs is by replacing those worn out electrical parts needed in your manufacturing equipment with quality reconditioned electrical distribution equipment and reconditioned electrical parts. Keep in mind that not all parts that need to be reconditioned have functional problems to begin with, the parts may simply have been leased and when the lease has expired the part may be returned and need to be reconditioned before being issued for sale. Reconditioned electrical parts are of similar quality as new parts, but simply cost a lot less.

As surprising as it may be, purchasing high quality reconditioned electrical parts can save your manufacturing company anywhere from 50% to 75% over purchasing new parts and when quality reconditioned electrical equipment is reconditioned properly they can last if those new parts as well.

Choosing the Right Reconditioning Company

Of course you don’t want to purchase reconditioned electrical distribution equipment from just any company that reconditions these types of parts you want to buy those reconditioned electrical parts from a company that has an excellent record for those parts they sell and you want to make sure that the company has excellent reviews from places such as the Better Business Bureau and Google as well as testimonials on the company’s website.

When purchasing reconditioned electrical parts even from a reputable company here are some things you want to know about the reconditioning process before purchasing those parts.

Here are a few of the questions you want to ask.

1) What type of electrical parts does the company recondition? Does it recondition and sell the types of parts your manufacturing company needs?

2) Does the reconditioning Company completely disassemble the use part and clean all the parts and examine them to ensure that each of the smaller individual parts are in good condition?

3) Is the reconditioned used part then repainted with quality paint to give it that new like look and help to protect the part?

4) Is the reconditioned part tested once it is put back together and does the reconditioned part meet or exceed the Manufacturers UL certification.

5) Does the reconditioned part come with some type of warranty, so you can be assured that the money spent on the used part won’t be wasted?

By purchasing high quality reconditioned electrical components manufactures can save significant amounts of money when replacing those old worn out electrical parts for you manufacturing machinery. If your company is looking to cut operating costs, then buying reconditioned electrical parts for a reputable company may be one way do so.
