The Importance of "Listed" in Energy Management Systems 

The evolution of technology has always posed challenges for safety regulations. A crucial tool at our disposal? The concept of items being "listed." But what does it mean to be "listed" in the realm of Energy Management Systems? 

Understanding 'Listed' 

According to Article 100 of the National Electrical Code (NEC), an item that's "listed" has undergone rigorous testing by a Nationally Recognized Testing Laboratory (NRTL). The aim? To ensure the product performs safely without endangering property or causing harm. However, being "listed" doesn't necessarily mean it's the best product, but rather it meets minimum safety standards. 

While Underwriters Laboratory (UL) is perhaps the most recognized, there are several other listing agencies, like Intertek, ensuring products meet these criteria. 

Energy Management Systems and 'Listed' 

The NEC has always been in a state of flux, constantly being molded by the insights of electrical professionals. The concern? Without listing requirements, any installer could craft an Energy Management System using unlisted parts that haven't been safety-evaluated by an approved laboratory. 

Realizing the gravity of this, the NEC Code Making Panel commented that revisions have been made for energy management systems to strictly adhere to industry safety standards. 

Importance of Authentic Listing 

As the global marketplace continues to grow, it's paramount to ensure imported goods, especially electrical components, satisfy safety standards set in the destination country. And this is where "listing" comes into play. It guarantees these components have undergone rigorous evaluations and won't pose safety risks. 

However, with the rise in the importance of product listing, counterfeit labels are becoming increasingly prevalent. Much like counterfeit currency, fake listing labels can pose significant risks. Several online resources assist professionals in distinguishing genuine labels from fake ones. 
 

Energy Management Systems must now be listed
in the 2023 Code cycle. Holographic labels are
more difficult to counterfeit.

2023 NEC - What's Changed?

2020 NEC 

In the 2020 NEC, Section 750.6 did not exist. Article 750 Energy Management Systems, was introduced in the 2014 NEC. 

2023 NEC 

In the 2023 NEC, Section 750.6 states the following: 

Energy management systems shall be one of the following: 

1. Listed as a complete energy management system 
2. Listed as a kit for field installation in switch or overcurrent device enclosures 
3. Listed individual components assembled as a system 

The 2023 Code in Action

The introduction of Section 750.6 offers manufacturers and installers flexibility. They can either opt for a comprehensive listed energy management system or assemble individual components that are separately listed to form a cohesive system. 

Looking Ahead 

As we progress into a future where technology keeps advancing at breakneck speed, regulations like the NEC will be even more crucial. Ensuring safety through listing becomes an indispensable step in guaranteeing that advancements do not come at the cost of safety. As professionals and consumers, staying updated, vigilant, and committed to safety standards will be the way forward. Always remember, a system is only as strong as its weakest link. Let's ensure every link is robust and reliable. 

Sample Video Script

[Opening Scene: A brightly lit room with a large table showcasing different electrical equipment and systems. Close-up of a label reading “LISTED” on one of the devices.] 

Scott: "You've likely seen this label countless times: 'Listed'. A mark of safety and reliability in our industry. But let’s delve a bit deeper into its significance." 

[Cut to a lab environment with professionals testing various equipment.] 

Scott: "The National Electrical Code tells us that a 'listed' item has been put through the wringer, tested meticulously by a Nationally Recognized Testing Laboratory." 

[Zoom into a computer screen displaying the Underwriters Laboratory (UL) website.] 

Scott (V.O.): "Now, most folks instantly think of UL. But remember, there are many champions in this arena, like Intertek, ensuring our products make the grade." 

[Montage: Electrical professionals working, discussing, and looking at blueprints.] 

Scott (V.O.): "With the NEC constantly adapting, we've heard from many in our field about the risks of Energy Management Systems built from unlisted parts. It's a real concern." 

[Cut to a large global map with animated ships and planes moving, indicating the import and export of goods.] 

Scott (V.O.): "Our world is more connected than ever. We get goods from every corner of the globe, and that makes ensuring our imported electrical components meet safety standards even more crucial." 

[Clip: Close-up of genuine and counterfeit 'listed' labels side by side.] 

Scott (V.O.): "And here's a curveball: counterfeit labels. Much like spotting a fake dollar bill, spotting these pretenders is crucial to our safety." 

[Fade into a graphic timeline transitioning from 2020 to 2023.] 

Scott (V.O.): "Fast forward to the 2023 NEC: The directive is crystal clear. Our Energy Management Systems need to be fully listed or built from components that are." 

[Final Scene: Close-up of a technician installing an energy management system, ensuring it has the 'listed' label.] 

Scott (V.O.): "As we push forward, adhering to guidelines like the NEC is our compass." 

Scott (on-screen, looking directly at the camera): "We have a responsibility to stay sharp, and above all, keep our systems both innovative and safe."
