How many receptacles are required within 18 inches of the top of the window for a 10-foot show window?

In a 10-foot show window, the National Electrical Code (NEC) specifies that at least one 125-volt receptacle should be installed within 18 inches of the top of the window. This requirement is in place to ensure that there is adequate access to power for any necessary equipment that may be utilized in or around the show window, supporting the display and operational needs.

The need for just one receptacle rather than two is based on the code's intent to provide adequate electrical supply while avoiding excessive installations that could lead to safety hazards or code violations. A single receptacle is deemed sufficient to meet the lighting or other electrical demands typically associated with show window displays.

This careful consideration ensures that installations are practical and focused on safety while adhering to both aesthetic and functional needs.
