Best Practices for Racking a Circuit Breaker In and Out Racking a circuit breaker in and out is one of the riskiest actions taken by an employee when it comes to safety and Arc Flash potential with Low Voltage and Medium Voltage gear. This is especially true when it comes to an aging electrical infrastructure.…

The Arc Quenching Switchgear is Game Changing Technology For those that have experienced an arc flash incident you know the impact it can have on your facility and more important to the personnel that potentially could be exposed to these events. Many times, when an arc flash incident happens equipment is lost, and down time…

Imagine if you could take your single line and bring it to life with data! It’s possible and in this video, Mike Rathbun walks you thru how to begin implementing this technology inside your facility.  As technology continues to evolve the ability to visualize data in a format such as a live single line and…

The Future in Circuit Breaker Technology is Here. The ability to access critical live data at the circuit breaker level exists and Eaton’s Power Defense line of breakers is the solution. In this video you’ll see how to maximize the data that is generated from this powerful line to impact your facility. Creating access to…

How to Start Monitoring Power This video tackles the journey that many people face when deciding to implement power monitoring at their facility. With so many different protocols, devices and networks it can be overwhelming to know where to begin. Whether you are just getting started with power monitoring or have a system in place…

There are several factors to consider when evaluating equipment requiring a new installation of power distribution equipment. Typically, these decisions will start at the utility to understand what they can support for large load connections.  It is important to make educated recommendations for the proper voltage design as it impacts the project as things progress. …
Are you responsible for maintaining the electrical distribution system at your facility? Tired of hearing “we’ve always done it this way?”. But knowing where to look and what to focus on can be overwhelming.  Fortunately, there are governing bodies that provide a framework for prioritizing what is important from a testing standpoint as it pertains…
It’s easy to get overwhelmed researching what your preventative maintenance for electrical distribution and switchgear There is more information out there than ever. Some have several hundred pages with only a few pages of relevant items that are actionable. You can spend hours reading and skimming through these documents only to be frustrated. To give…
How Close Can I Get To My Gear? The first and most important thing to consider when being around electrical systems is to determine if a hazard is present. A hazard is defined by the NFPA 70E as “A source of possible injury or damage to health”. There are two major hazards associated with electrical…

Recommended Transmission Media Selection Criteria Industrial Ethernet offers a wide range of transmission media such as copper and fiber. It can be difficult to choose the best media for your application. The following are criteria to consider. Ensure cabling is specified to withstand high voltage, noise, harsh, and potentially hazardous environments factors: Shielded cables are…

Motors are expensive and essential. We’ve defined these standards of motor protection:   Motors can be damaged or destroyed under any of the following conditions: Low or high supply voltage Phase unbalance Continuous excessive loading Single-phasing Jam or stall conditions Ground/earth faults Mechanical failures such as seized motor bearing or binding mechanical linkages   Consider…

Proper electric motor balancing and precision machine work will extend the life of your motor, particularly the bearing life. So ask yourself this question, “How much could one extra year of run life on every motor repaired save you?” Answer: 14% if you are averaging 6 years, which could add up to thousands.   Electric motor…

Inspection is a critical portion of the motor repair job, and it defines the entire scope of work. You want answers to critical questions before you send a motor out for repair. You want to know: How thoroughly and accurately will the motor be inspected? What determines that the motor repair was successful and that…

  The ODP vs TEFC debate has been extensively covered by others, but our repair shops find evidence of poor performing ODP applications on a monthly basis. Open drip proof motors are just that – open. It’s like an open door from whatever is outside, to your bearings and windings on the inside. At one…

Selecting NEMA motors- TEFC, severe duty, or IEEE 841 Making the right choice for low voltage motors can greatly affect total cost and reliability. There are so many types and manufacturers of motors that it can be difficult to make the right selection for any given application.  Our test teams and repair shops will occasionally…
