Choosing A Fuse

Having the correct fuse for your electrical needs is imperative for the safety of yourself and your equipment. A blown fuse can be frustrating and sometimes make you wonder if a fuse should even be part of a circuit, but they are essential in protecting users from shock and catching fire. Any device that is powered by a low-impedance source will need a fuse, whether it’s an item that plugs into the wall or one that’s run by a battery or an alternator in a car. In the article found here, it goes into further detail about which type of fuse to look for depending on your electrical needs. Other factors to consider is the speed and size of the fuse that you plan to install. Often, a simple comparison to the existing fuse can be used to determine a good replacement option.

Why Power Factor Correction Is Important

In the article, it explains several reasons why it is important for electrical loads in industrial settings to be measured and have power factor correction. Power factor is used to measure active, working power and it is ideal to have a 1.0 rating, which means all the power is going towards performing work. The farther the power factor is from 1.0 the less efficient the system will be and produces more strain on the equipment from the higher currents. Three benefits to correcting the power factor include: lowering utility bills, reducing power and loading on the distribution network, and lessening carbon emissions. There are several ways for industrial and commercial operations to correct their power factors; such as, adding capacitor banks that counteract the cause of low power factor, removing wasted energy and its harmful effects.

Avoiding Electrical Hazards In Your Work Environment

During any type of job, there are always electrical hazards that are sometimes ignored or not thought to be dangerous until disaster strikes. Many unexpected accidents can be prevented with the proper care and knowledge of electrical safety. On item specifically, that is popular in many offices on chilly days, is the use of space heaters. These warming devices although keep personnel more comfortably warm while working but they also demand a fair amount of energy, so it is best to always have them plugged directly into a wall and never use extension cords, power strips, or surge protectors.  By plugging in too many items into one power source, a risk of blowing/burning up circuit breaker or even starting a fire. In the article, they further discuss using proper tools for any job inside or outside in order to use proper electrical equipment for safety needs.

Preventing Breakdowns and Fire Hazards with Thermal Inspections

Having to deal with unexpected downtime with failures due to a damaged electrical panel can create big headaches with a big price tag for repairs for companies to have to handle. If connections or components overheat, there are many risks including a fire hazard with electrical shorts. One of the biggest problems during an inspection is not all problems with an electrical panel can be seen visibly which is why a solution for this could be a routine inspection with the use of thermal cameras that can read accurate temperature readings from a safe distance. In the article, the inspection with proper tools is suggested for this preventative measure done by FLIR company. Having proper maintenance and repairs done is always key to running a successful business no matter the size or nature. If ever in need of replacement parts for your electrical needs, JP Electrical Company specializes in your electrical needs and are happy to answer any questions.

More Details Emerging on Digital Circuit Breakers

Many aspects of the electrical industry are all transitioning to a more digitized world which is now including the digital circuit breakers. Traditional mechanical circuit breakers have been around since the late 19th century when Thomas Edison first came up with the idea. Many homeowners are familiar with their circuit breakers when a fuse is blown and a person has to go looking in the dark for a switch to turn back on but, on a commercial aspect of the situation, it can be very dangerous, since commercial building’s electrical panels are slow enough that it still allows short circuits or arc flashes that can, in bad situations, even kill people. In January of this year, a company called Atom Power was the first to pass a test to bring digital circuit breakers to the market. In this article, the author further explains what makes a digital circuit breaker not only safer to utilize, but also can help eliminate other products that will be no longer needed. There is great potential in this new-found technology and surely Atom will not be the only company to continue research and development on these coming into the future.

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.

Preventing Transformers from Exploding with Flexible Tanks

Transformer explosions are relatively rare, in fact, only less than one percent will explode. Although this percentage is very small when they do explode it can be very deadly and cause a large interruption with toxic fires or even oil spills. Canadian power supplier has collaborated with comapny ABB on a recent project to design a transformer tank to be more flexible to allow the pressure buildup from inside to expand without causing a rupture or explosion. To read more on how the ABB calculated the measurements and materials needs in order to create this new alternative read this article. This new product will be able to prevent most tanks from explosions thus creating a safer area for people who work near these transformers and also to the environment with less risk of oil spills and fires.

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.


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.
