I have had several debates online regarding the changes made to 210.52(C)(3) in the 2023 NEC. Specifically, the removal of the language that allowed a receptacle installed less than or equal to 12 inches below the countertop, with an overhang of 6 inches or less, to be counted as serving the countertop. Many have interpreted this as prohibiting ANY receptacle from being installed below the countertop surface. I disagree, as there is no language that says receptacles shall not be installed below a countertop, but rather, just a lack of language allowing such a receptacle from being used to satisfy the requirements of 210.52(C)(2).
In addition, in the case of an island or peninsula that divides a room or rooms, a receptacle may be required by 210.52(A), which is not required to satisfy the requirements in 210.52(C)(3), is allowed to be up to 5½ feet above the floor and is prohibited from being above the countertop by 210.52(C), so it may be necessary to install a receptacle in such a location.
There is also no language prohibiting installation of a nonrequired receptacle just for convenience of the end-user. What is your interpretation of this language change?
The NEC is made up of “mandatory” and “permissive” rules as defined in Section 3.1 of the NEC Style Manual. Both styles of rule establish mandatory language; a permissive rule does so by providing the Code user options for compliance.
Section 210.52(C)(3)(1)-(3) is a permissive rule that lists permitted installation locations for receptacles intended to serve a peninsular or island countertop or work surface. By excluding the location below a countertop or work surface as an option, such installations would be prohibited by rule.
However, you are correct in that a receptacle installed below the countertop or work surface that is not intended to serve the island or peninsular countertop/work surface, but as a required wall space receptacle or convenience receptacle, would be permitted.

Can a receptacle installed behind a wall-mounted TV be counted as one of the required receptacles for the wall space above a work area or countertop, or is it considered not accessible?
For the receptacle to count as one of the receptacles serving the countertop or work surface, the location of the receptacle must comply with Section 210.52(C)(3), which includes language requiring the receptacle to be readily accessible. A receptacle
installed behind a wall-mounted TV would likely not be considered readily accessible, as the TV may need to be removed from the mount to gain access to the receptacle.

The 2023 NEC introduced specific restrictions on receptacle installation locations for islands and peninsulas, clarifying what is allowed—and what is prohibited—below countertops and work surfaces. These changes were made due to injuries caused by pulling appliances by their cords draped over the edge of the countertop. The 2023 NEC includes some key requirements.
Required receptacles for islands and peninsulas: If a receptacle outlet is provided to serve an island or peninsular countertop or work surface, it must comply with 210.52(C)(3) and (C)(4). If no receptacle outlet is installed, provisions must be made for future installation.
Permitted locations [210.52(C)(3)] include being placed on or above the countertop or work surface, but not more than 500 mm (20 inches) above. Also, in a countertop or work surface, listed receptacle assemblies should be used for those locations. Receptacles that are not readily accessible due to fixed appliances, sinks, rangetops or appliance garages cannot count toward these requirements.
Prohibited locations [210.52(C)(4)] include below the countertop or work surface, except if located in a drawer. In addition, receptacles on adjacent walls extending from base cabinets within 610 mm (24 inches) of the countertop are also prohibited. Receptacles beneath countertops must not be located within 610 mm (24 inches) of the countertop or work surface.
Planning for future receptacle installations is critical if outlets are not immediately installed. The 2023 NEC provides clear direction: receptacles below countertops (other than in drawers) are prohibited for islands and peninsulas. Designers and contractors must install receptacles on, above or in listed countertop/work surface assemblies, and plan for accessibility, future-proofing and compliance. This change is a response to injury statistics and seeks to increase safety, usability and alignment with modern installation practices.
