Article 725: From Complexity to Clarity 

Article 725 of the National Electrical Code (NEC) has seen some substantial changes in its 2023 edition. This transformation is not just a matter of content, but also a redesign towards user-friendliness. Let's dive into what this change means for electrical professionals. 

HVAC systems are one of the most common uses of Class 2 wiring and circuitry.

2023 NEC - What's Changed?

2020 NEC 

Back in 2020, the NEC housed the requirements for Class 1, 2, and 3, as well as remote-control and signaling circuits, all under a single article titled "Class 1, Class 2, and Class 3 Remote-Control, Signaling, and Power-Limited Circuits." Non-power-limited Class 1 circuits were also covered within this comprehensive article.

2023 NEC 

In the 2023 NEC, the title of Article 725 explains it clearly: Class 2 and Class 3 Power-Limited Circuits. Remote-control and signaling circuits are considered as a subset of Class 2 and 3 circuits and so there is no reference to them in the title.  

Important changes to Article 725: 

• All references to Class 1 circuitry were removed and moved to new Article 724. 
• Some sections have been re-worded for clarity. 
• The numbering of sections has changed. 
• The definitions have been moved from Section 725.2 to Article 100. 
• Non-power-limited Class 1 circuits are now covered by Chapters 1 through 4 of the NEC. 

The 2023 Code in Action

Despite these changes, the actual installation procedures for Class 2 and 3 power-limited circuits remain largely similar. However, the streamlined code will be a boon for newcomers in the electrical field. The revamped article layout and clearer language facilitate easier learning, retention, and application of the rules. This not only assists installers but also the Authority Having Jurisdiction (AHJ) in applying the Code to real-life situations. The end goal? Safer, more effective electrical installations aligning with the NEC's primary mission: safeguarding individuals and property against electrical hazards. 

Change is an integral part of growth, and the 2023 NEC’s revisions to Article 725 are a testament to that. By refining language, reformatting, and re-allocating content, the NEC has made strides towards clearer, more accessible guidelines for the future of electrical installations. As professionals, it's our duty to stay updated and ensure we're providing the safest electrical solutions possible.

Scott: "We're diving into the redefined world of the 2023 NEC's Article 725. This article has seen a substantial transformation, and I'm here to guide you through it." 

[Cut to a split screen showing the 2020 NEC's Article 725 title next to the 2023 version.] 

Scott: "At a first glance, you'll notice the title has been streamlined. Gone is the exhaustive title from 2020, replaced with a concise "Class 2 and Class 3 Power-Limited Circuits" in 2023." 

[Fade to a flowchart illustrating the shift of Class 1 content to Article 724.] 

Scott: "The most significant change? All references to Class 1 circuitry have made a move to the brand new Article 724. This leaves Article 725 with a clear focus on Class 2 and 3 circuits." 

[Transition to close-up shots of the 2023 NEC book, highlighting the reworded sections and changes in section numbering.] 

Scott: "With this edition, you'll find enhanced clarity. Some sections have been reworded, and the numbering has seen a shift. Oh, and remember the definitions in Section 725.2? They've found a new home in Article 100."

Scott: "What does all this mean for you? While the core installation methods remain familiar, navigating the requirements is now more straightforward – especially for those just stepping into our electrifying world." 

[Cut back to Scott with a smile.] 

Scott: "The 2023 NEC’s vision with these changes is clear: make electrical guidelines more accessible and user-friendly. By doing so, they're not just simplifying our jobs, but also reinforcing the commitment to safety."
