Question: The questions specifically is, would a counter mounted under a full-height pass-though window count as a peninsula? The issue being that there is no "wall" or backsplash to mount the required receptacles. Pop-up receptacles in the counter also won't work due to equipment on either side of the sink. Can't drill a hole in the top of the dishwasher to accommodate a pop-up outlet! If we could count this as a "peninsula", it would solve the problem, but it's not clear (to me) what NEC, or specifically CEC, considers a "peninsula".

Let's break down the electrical code requirements and whether your counter qualifies as a peninsula.

Understanding the Code Requirements (NEC/CEC)

The National Electrical Code (NEC) in the US and the Canadian Electrical Code (CEC) have similar requirements for receptacles in kitchens. Generally, they mandate receptacles along kitchen countertops, including specific requirements for peninsulas and islands. General Countertop Receptacle Rule

Receptacles must be installed so that no point along the wall line behind the countertop is more than 24 inches horizontally from a receptacle outlet.


Island and Peninsula Countertop Receptacle Rule

Island and peninsula countertops 24 inches or greater in length require at least one receptacle outlet.The tricky part is how "peninsula" is defined. The codes often lack a formal, strict definition. It's usually interpreted based on the function and shape of the countertop.

Does Your Counter Qualify as a Peninsula?


Based on your description, here's an analysis: It's a Counter

You've clearly stated it's a counter.


It's Attached to a Wall (Indirectly)

Although it's not directly attached to a solid wall, it is part of a counter that runs from a full wall.

Does it divide the kitchen?
This is a trick question, a peninsula can certainly define two areas within the kitchen.

Arguments
FOR it being a Peninsula



Extending From The Wall

Most interpret this to mean that a peninsula must extend out from something. In this case a regular counter running from the full wall.

Functional Division

Peninsulas often function to separate the kitchen from another space (dining area, living area). Your counter, even under a window, creates a visual and functional division.


Countertop Area

Your counter provides significant countertop area that is useful for food preparation, serving, or other kitchen activities.

The
Spirit of the Code

The intent of the code is to provide accessible power for appliances used on countertops. Your counter is clearly designed to be used as a countertop, making accessible receptacles essential.

The Lack of a Backsplash/Wall

This is your biggest hurdle. The codes often envision receptacles mounted in a backsplash. Your situation eliminates that option. Here's how to address this:


Code-Compliant Alternatives

Since a typical backsplash mounting isn't possible, you need to find code-compliant alternatives. This could involve:

Side-Mounted Receptacles

Can you install receptacles on the
sides of the cabinetry supporting the counter, facing the countertop? Ensure these locations meet height requirements and are protected from spills.

Recessed Receptacles

Look into countertop recessed receptacles that lay mostly flush with the counter. These could be installed into the countertop, with the box mounted below. Be sure to check that these products are suitable for wet locations if they are close to the sink.

Surface-Mounted Raceway

Consider running a surface-mounted raceway along the
underside of the window frame, if applicable. Receptacles could then be mounted to the raceway. This is a less visually appealing option, but sometimes necessary.

Base Cabinet Face

Install receptacles on the face of the base cabinets that support the counter.

Permit Official Discussion



The most crucial step is to talk to your local building inspector or permit official.
Explain the situation, present your alternative solutions, and get their approval before you proceed with the installation. Their interpretation of the code and what they will accept is what ultimately matters. Documentation

Document everything! Keep records of your conversations with the inspector, the code sections you are referencing, and the specifications of any alternative solutions you are proposing.

In summary

While the code definition of "peninsula" is open to interpretation, you have a strong argument for it being one. However, the bigger issue is the lack of a traditional backsplash.

Your key is to find code-compliant alternative receptacle locations and get approval from your local building inspector before you start work.
