No, the code requirement likely would not be met. Here's why, along with the relevant section of the National Electrical Code (NEC) that covers this

NEC 210.52(C)(2) Island Countertop Receptacles:
"At least one receptacle shall be installed at each island countertop with a long dimension of 24 inches or greater and a short dimension of 12 inches or greater." "Receptacles required by 210.52(C)(2) shall be located above, but not more than 20 inches above, the countertop or work surface."Why the proposed location fails


Height

The proposed receptacle is 10" below the countertop, not above. The code specifically requires it to be above the counter and no more than 20" above.2.

Accessibility and Intended Use

Even if the height were correct, the fact that it's behind a cabinet door raises accessibility concerns. Receptacles in kitchens are intended for countertop appliances that need to be plugged in and unplugged easily. Having to open a cabinet door every time makes it impractical and arguably defeats the purpose.3.

Clearance Issues Electrical codes require safe operation and maintenance. If the receptacle is behind a cabinet door, there may not be sufficient clearance to easily plug in and unplug equipment.

In summary, placing a receptacle inside a cabinet and below the countertop is a clear violation of NEC 210.52(C)(2).What to do instead



Install a receptacle above the countertop

This is the simplest and most compliant solution. You could use a standard receptacle mounted on the side of the island, a pop-up receptacle, or a receptacle strip under the edge of the counter.

Install a receptacle on the face of the island

You can mount a receptacle on the visible face of the island, near the end, but still accessible and not behind a door. Make sure it's at an appropriate height (above the floor, but not below the countertop).*

Consider code-compliant alternatives

If aesthetics are a major concern, consult with a qualified electrician. They might suggest alternatives that meet the intent of the code while being more visually appealing (e.g., specialized receptacle strips).

Important Note: Always consult with a licensed electrician to ensure that your wiring and receptacle installations meet local codes and are safe. Codes can vary by jurisdiction, and a qualified electrician will know the specific requirements in your area. Flag for review
