In this scenario, each show window has a length of 15 feet, and according to the National Electrical Code (NEC) and related practices, it is important to ensure adequate convenience and safety in electrical installations.

The NEC recommends that for display areas, such as show windows in retail spaces, receptacles be strategically placed to avoid the use of extension cords and to facilitate easy access for lighting and other electrical displays. This guideline typically specifies a minimum number of receptacles based on the length of the space to ensure sufficient and effective coverage.

For a 15-foot show window, having two receptacles allows for flexibility in arranging display lighting and any other electronic devices that may be required. This setup helps meet the code requirements and ensures that the jewelry store can effectively utilize its display space without running into potential hazards associated with overloaded or inaccessible outlets.

Therefore, having two receptacles per window covers the practical needs of the store, promoting safety and convenience for usage in retail display environments. This approach supports effective merchandising while also adhering to electrical standards.
