    Determining short circuit current ratings

    Calculate SCCR
    The short circuit current rating (SCCR) of a control panel is a critical figure to determine in order to adequately protect people who work on or around power equipment.

    One device multiple functions

    Convergence
    The many benefits of combining multiple functions in a single device provide a compelling reason for device convergence. At home, at work ... and now in power control equipment like switchgear and panels ... the benefits are impressive.

    Panel component inter-compatability

    What you didn't know about panel component inter-compatability
    The contents of an electrical control panel may seem complex, but when broken down into the different sub-systems, it all starts to make sense. As you start to understand how the components, enclosure, and various hardware interact, you start to realize that it makes sense to select components designed with interoperability in mind.

    DIY control panels

    The dangers and downfalls of do-it-yourself control panels
    Do-it-yourself is a great idea for many things; but when it comes to building electrical control panels, it may be a bad move. Read this article to learn about the downfalls and dangers of building your own control panels.

    Discovering hidden breaker functions

    Discovering hidden breaker functions
    We often fail to take advantage of powerful features in our electronic devices, usually because we didn’t know they were there. Managers at facilities equipped with ABB’s Emax 2 breaker are excited when they discover it includes a full-function Network Analyzer. The Emax 2 enables extensive power-quality analytics and alarms that help protect plant equipment from power-related problems like voltage sags, spikes, and harmonics.

    Protecting power distribution systems

    Protecting power distribution systems with modified differential ground faults
    In power distribution systems that rely on parallel energy inputs, or include multiple inputs that are switched in and out, it is critical to protect the system from ground faults. Rather than simply disconnecting the entire system, though, modified differential ground fault protection systems allow only the faulted equipment to be disconnected while the rest of the system remains operational.

    Universal machine safety relay

    Evolving toward a truly universal machine safety relay
    Machine-safety relays have evolved in the decades they’ve been used in the safety circuits that protect machine operators from injury. But in the past, they remained a specialized component that typically couldn’t be swapped between applications. Today, however, maintenance managers can select truly universal relays that simplify maintenance and minimize inventory.

    More-efficient solar BOS

    Capitalizing on more-efficient solar BOS (Balance of System) products
    “Never leave money on the table,” is a frequently heard business-related saying. The advice is sound; don’t fail to capture all the potential profitability or value in an action or transaction. Most solar installers, however, fail to follow that excellent advice when it comes to selecting components for the balance of systems (BOS). Find out how component selection directly impact solar farm profitability by through efficiency and reliability.

    Connecting panels to the IIoT

    The migration from analog to digital control panels is accelerating. Driven by the promise of increased control, improved maintenance, and optimized processes, panel builders and buyers are increasingly looking for ways to connect to the Industrial Internet of Things.
