The 2023 NEC introduces a notable change to include the use of acronyms for clarity and efficiency. For instance, a ground-fault circuit interrupter can now be referred to by its acronym, "GFCI". But did you know there are different types of GFCI devices? If you saw the term SPGFCI in the Code, would you know what type of device it refers to? Dive deeper into how the acronym "GFCI" and its variations are used in the NEC by watching the video. To follow along with this video, you can download the

The NEC does not limit the number of lighting outlets or receptacle outlets on a 15 general-purpose lighting/receptacle branch circuit. However, per 210.11(A), "the minimum number of branch circuits shall be determined from the total calculated load and the size or rating of the circuits used." For example, a 2400 sq ft dwelling unit would require four (4) 15A, 120V circuits. Check out Example D1(a) in the NEC and the video for the details.

Although the rule of six grouped service disconnects didn’t change, disconnects are now required to be compartmentalized to reduce the hazards associated with arc-flash and arc-blast. This might not seem like a big change but, it makes most of the available multi-meter centers and switch boards ineligible for use to meet these requirements. | Mike Holt Enterprises
