Unpacking the 2023 NEC Changes: Garage Circuitry Edition 

Understanding the intricacies of electrical standards can be daunting. With each new edition, the National Electrical Code (NEC) offers nuanced guidelines ensuring both safety and efficiency. In 2023, a focus on dwelling-unit garages took the spotlight. Here, we’ll guide you through the essential changes and their implications for both electricians and homeowners. 

2023 NEC - What has changed?

2020 NEC  

In the 2020 NEC, Section 210.11(C)(4) Branch-Circuits Required, Dwelling Units, Garage Branch Circuits, stated:   

In addition to the number of branch circuits required by other parts of this section, at least one 120-volt, 20-ampere branch circuit shall be installed to supply receptacle outlets required by 210.52(G)(1) for attached garages and in detached garages with electric power. This circuit shall have no other outlets.  

Exception: This circuit shall be permitted to supply readily accessible outdoor receptacle outlets.  

2023 NEC  

The 2023 NEC, Section 210.11(C)(4) Branch-Circuits Required, Dwelling Units, Garage Branch Circuits, now requires the following:  

In addition to the number of branch circuits required by other parts of this section, at least one 120-volt, 20-ampere branch circuit shall be installed to supply receptacle outlets, including those required by 210.52(G)(1) for attached garages and in detached garages with electric power. This circuit shall have no other outlets.  

Additional branch circuits rated 15 amperes or greater shall be permitted to serve receptacle outlets other than those required by 210.52(G)(1).  

Exception No. 1: This circuit shall be permitted to supply outdoor receptacle outlets.  

Exception No. 2: Where the 20-ampere circuit supplies a single vehicle bay garage, outlets for other equipment within the same garage shall be permitted to be supplied in accordance with 210.23(B)(1) and (B)(2).  

Notice the new permission to supply receptacle outlets in the garage beyond those directed by Section 210.52(G)(1). Section 210.52(G)(1) requires one outlet installed in each vehicle bay at a height not to exceed 5-1/2 feet.  

Notice the new permission to include 15-amp branch circuits to supply outdoor receptacles with no restrictions.  

Also notice the new Exception No. 2, which allows 10-amp branch circuits according to 210.23(B)(1) and (B)(2). 

In the 2023 NEC, outdoor receptacles are permitted to be supplied by the required 20-amp garage branch circuit, even when the receptacles are not readily accessible.

The 2023 Code in Action

The recent modifications to the NEC make garage wiring more adaptable. Electricians now have a broader scope when deciding power allocation, which could result in more user-friendly setups. 

For example, the new permissions provided by the 2023 NEC means outlets beyond those dictated by Section 210.52(G)(1) can be supplied. This section had previously demanded an outlet in each vehicle bay, no higher than 5-1/2 feet. 

The inclusion of 15-amp branch circuits, coupled with provisions for 10-amp circuits, indicates a more inclusive and versatile approach, enhancing adaptability to diverse needs. 

But, in line with the NEC's foundational principles, safety remains paramount. GFCI protection, governed by Section 210.8(A)(2), is essential for all garage receptacles. 

Looking Forward: 

The shifts in the 2023 NEC reflect a progressive approach, balancing innovation with unwavering commitment to safety. As electricians adapt to these new guidelines, homeowners can expect more tailored electrical solutions. As the NEC continues to evolve, it’s evident that we're moving towards a future where electrical setups are both efficient and safe, marking a bright trajectory for all involved.

Scott (V.O): "Hello everyone! It's Scott here. Today, we're diving deep into the 2023 NEC's updates focusing on dwelling-unit garages." 

[Cut to Scott, wearing safety gear, standing next to the electrical panel.] 

Scott: "With every NEC update, there's always a balance between ensuring safety and upgrading for modern efficiency. The 2023 version is no different." 

2023 NEC - What has changed? 

[Animation: Number '1' appears with an electric plug icon.] 

Scott: "First up, there's increased flexibility with the 20-amp garage circuit. Now, more receptacle outlets can be connected than before, expanding beyond just the required ones in the vehicle bays." 

[Animation: Number '2' appears with a flashing light bulb.] 

Scott: "Secondly, the 15-amp branch circuit makes an entrance! If you're aiming to supply garage receptacles, this one’s a game-changer, as long as they're not specifically meant to comply with Section 210.52(G)(1)." 

[Animation: Number '3' appears with an outdoor plug and green checkmark.] 

Scott: "The third change? Outdoor receptacle outlets! The dedicated garage circuit now has a broader scope, including those that aren’t readily accessible." 

[Animation: Number '4' appears with a garage outline and a 10-amp plug.] 

Scott: "And last but not least, if you have a single-bay garage, the 20-amp circuit can now support outlets for other equipment, especially when they’re aligned with 10-amp branch circuits." 

[Cut to Scott holding an outlet and pointing towards the specified height on the garage wall.] 

Scott: "Remember the old mandate from Section 210.52(G)(1)? It required an outlet in each vehicle bay, no higher than this — 5-1/2 feet. The 2023 NEC now offers more than this, allowing electricians to think outside the box." 

[Close-up of Scott’s hands, showcasing different circuit breakers.] 

Scott: "With the new 15-amp and 10-amp branch circuits in play, it’s clear that the NEC is embracing adaptability, paving the way for diverse setups in our garages." 

[Pan to GFCI protected outlet.] 

Scott: "But amidst all these changes, some things remain constant. Like the GFCI protection - essential for every garage receptacle, ensuring your safety remains paramount." 

[Cut to Scott leaning against the car, looking contemplative.] 

Scott: "It's always fascinating to see the NEC evolve. With each update, electricians like myself have new challenges and solutions to consider. And for homeowners? Well, there's the promise of setups that are even more in tune with their needs." 

[Cut to a wide shot of Scott, waving with a smile.] 

Scott: "That's a wrap on our deep dive into the 2023 NEC garage updates!"
