At least one 125-volt, single-phase, 15- or 20-ampere receptacle is required within 18 inches of the top of each show window.

**Code Change Summary:** The number of receptacles required for a show window is now determined differently.

A show window is the area at the front of a store for displaying merchandise. A code change in 2017 to the definition made it clear that show windows also include the area above the door.

In the 2020 NEC^{®}, receptacle requirements for a show window were determined based on *each 12 linear feet or major fraction thereof of show window area, measured horizontally at its maximum width*.

In the 2023 NEC^{®}, the confusing method to determine receptacle requirements for show windows has been changed and is now significantly easier to comprehend.

Now, at least one 125-volt, single-phase, 15- or 20-ampere receptacle is required within 18 inches of the top of each show window, and there must be no point along the top of the window that is farther than 6 feet from a receptacle outlet.

The NEC^{®} has specific rules for show windows:

- Section 210.62 requires at least one 125-volt, single-phase, 15- or 20-amp receptacle to be installed within 18 in. of the top of a show window and for no point along the top of the window to be farther than 6 feet from a receptacle outlet.
- Section 220.14(G) requires an allowance of 200 volt-amperes per linear foot of show window to be used when calculating the branch circuit load for the show window.
- Section 220.46 requires an allowance of 200 volt-amperes per linear foot of show window to be used when determining the overall load from the show window circuits on the feeder or service.
