Just before spring New Jersey residents got a taste of what serial nor’ easters can do. In fact the entire New York metro area was impacted with power outages and utility company faliures.
We were hired by Lundbeck research, at 215 College Road in Paramus, NJ. The project consisted of removing their existing 500 KW Caterpillar generator, seen here, and installing a new 1500 KW Cummins generator. Because of the size and the weight of the generator we had to higher a crane that required the installation of extra counterweights due to the massive weight of the new generator.
The enclosure was 14′ wide, and 37′ long. The total weight that we had to lift up with this crane was 71 thousand pounds, and then that had to be strategically set in place over the existing conduits stubbed-up out of the new concrete pad to support all the weight of that generator.
The employees of Academy Electric, seen here straightening out all of the lifting straps, because every one of them has to be strategically located so that when we lift this massive weight, everything comes up nice and even. We are now positioning the straps to get them located into the eight pit points that we had to use to pick up the weight of this generator. Continue reading Installing a new 1500 KW Cummins Generator

As we move from hurricane season into winter storm season, back-up power has become top of mind with the unprecedented power outages left from hurricanes Harvey, Irma and Maria. But winter storm from nor’easters to ice storms can still cause devastating power outages.
So, what’s the difference between the various standby power sources, and what should you be asking your customers to think about? Primarily, it’s their preferences – how big of a unit do they need; how important are aesthetics and acoustics noise levels; do they need features like remote monitoring and load management? These are the questions that we think about at Cummins when we’re designing a new generator. We examine how each of these factors affects the design of our systems, and then we test those designs and refine them further. It’s what we’ve been doing for almost 100 years.
When we started to design the new Quiet- Connect series of home standby generators, our goal was to create a smaller, quieter gen- erator than previous designs. We thought carefully about the type of sheet metal that we used, its thickness and shape, as well as the air movement scheme and all of the enclosure elements. We moved from carbon steel to aluminum, and studied the noise level, air movement and discharge.
Revolutionary Architecture Created To Meet Aggressive Noise Targets
As part of our commitment to the Technology for a Quieter America Project, we had aggressive noise targets as we were designing the enclosure. In order to meet those goals, we created a revolutionary architecture with a dual wall enclosure and engineered air flow path. The design is essentially a box within a box that allows for minimal noise output. Then, the acoustic noise of each compo- nent was tested, refined and perfected by Cummins. Analysis Led Design (ALD) with Acoustic Noise Modeling played a significant role in achieving the lowest noise levels with fewer engineering resources and helped us in developing this design and noise control solution in the shortest possible time frame.
We developed our Acoustic Noise Modeling technology in 2010 based on a very precise noise modeling technique. The predictive capability is exceptionally accurate. It’s one of the things that helped us to design this revolutionary series of generators, and it moves us toward improved noise levels with every new design. As part of the development of the QuietConnect product, we completed 10,000 hours of verification testing looking at all aspects of its ambience at our state-of-the-art Acoustical Technology Center (ATC) in Minnesota. We also performed multiple iterations of competitive benchmarking to ensure that the new QuietConnect series is reliable, robust and exceeds market expectations.
Engineered For Optimal Performance
Our commitment to intentional design helps Cummins to remain competitive. Each and every component that goes into an assembly is purposefully engineered to meet a specific purpose. For instance, rather than a simple form bent and welded sheet metal, we use multifunction components. The base pan has specific features formed into it for housing adaptation, the alternator and the battery. The enclosure is a tooled component. The engine and alternator are Cummins designed, as is the fan, which was created to balance the required air flow through the enclosure. The muffler was also designed and developed by Cummins to attenuate noise levels at targeted frequencies to optimize exhaust noise performance of the engine. We think about each piece of the generator for optimal performance.
We took a similar approach with the electronics and software integrations. We developed a single master control that manages the engine, safeties, start-stop functionality, as well as the electronic governing and alternator output. We built in remote monitoring functionality and are able to offer it to our customers free of charge. The system is cloud based so it’s plug and play. All that is required by installers is to enter just a few parameters on our webpage and the genset can be controlled and managed from anywhere in the world. Installation takes 20 minutes or less – there are no firewalls or expert computer skills needed.
With remote monitoring, users can check on and receive notifications on genset status as well as manually start and stop their generators remotely, allowing them to manage energy output through an extended power outage or limited fuel supply. Users can access remote monitoring via the app for iPhone or Android, as well as through a web browser. Homeowners can also grant access to their local dealer, who can manage and perform routine maintenance quickly and easily.
Intelligent Load Management System And Refined Excercise Scheduler
To simplify installation, Cummins has used a simple control scheme between the transfer switch and the generator only three wires are required from the genset to control the transfer switch and up to eight additional wires to control optional remote display and load management accessories Connections are right inside the access door, making for a very quick and straightforward install.
Another key feature of the QuietConnect series is the intelligent load management system. Our control system continuously monitors how much current is consumed by each of the managed loads. This allows our control to make much more proactive and intelligent decisions about when to add or shed a load circuit. This means that homeowners are getting the optimal level of power and conven- ience from their generator, while other systems completely lock out managed loads, even when there is ample generator capacity.
Another new feature on these gensets for the fuel and noise conscious is the refined exercise scheduler. In addition to weekly, biweekly and monthly exercise options, customers can choose a new option called “crank only.” With this feature active, at every other scheduled exercise period, the genset will crank the engine but not start and run up to full operating speed. During the engine cranking, the control system is able to run a full set of diagnostics to ensure everything is working properly. During the crank only exercise cycle, the control is able to check oil pressure, battery voltage, voltage and speed signals, and more. This feature gives homeowners confidence in their standby power source while decreasing fuel consumption and neighborhood noise. At the next scheduled exercise interval, the genset will conduct a typical, full engine speed exercise.
Integrated Design Offers Affordable Easy-to-Install Solution
Cummins also offers a full line of accessories including load management contactor kits, remote displays, cold weather starting kits, composite mounting pads and a full line of transfer switches including an integrated transfer switch and load center in one box. This integrated design combines two separate electrical products into one, offering an afford- able, easy-to-install solution that takes up 50 percent less space on the homeowners’ wall.
The QuietConnect series is NFPA37 rated, which means it has been flame tested and approved to be installed within 18 inches of a home or building structure. This can simplify and allow for more aesthetically pleasing installations.
As the winter season approaches and power outages caused by ice and snow storms can lead to heat outages as well, we’d encourage you to talk to your customers about the importance of back-up power. You can help them understand the importance of remote management, an NFPA37 rating, and the benefits of a quick install. Losing power can be an expensive endeavor, particularly when the outage is prolonged. And now, you can offer your customers a thoughtful solution that’s easier to install, easier to manage, and has the Cummins heritage built in, so that your customers don’t get left in the dark when a storm hits.

Keeping your food safe while the Power is Out . . .
- Keep the refrigerator and freezer doors closed as much as possible to maintain the cold temperature.
- Note: The refrigeratorwill keep food cold for about 4 hours if it is unopened.
- Note: A full freezerwill keep the temperature for approximately 48 hours (24 hours if it is half full) if the door remains closed. It’s a good idea to have an appliance thermometer in the freezer.

We have always operated under the philosophy that true value in any work is the quality of the work that gets done. I know a lot of times it’s money but sometimes if you spend 10% more on the original installation you save 50% on making repairs to an inferior installation with an inferior product. So do it once, do it right and you don’t have to come back and do it again.
By having Academy Electrical Contractors come in we can save the facilities managers the expense and the scheduling nightmare of having two contractors. We take care of all your electrical contracting work whether it’s repairs, upgrades, new installations and while we are they we can also take care of your emergency generator. We can maintain your generator, we are factory authorized for Cummins and Kohler which are the two big players so if it needs to be repaired or maintained we have the expertise to take care of that. – Dan O’Brien
