What is the maximum distance a receptacle can be from a window to meet the requirements for a show window?

The maximum distance a receptacle can be from a window to meet the requirements for a show window is 18 inches. This provision is included in the National Electrical Code (NEC) and is designed to ensure that electrical outlets are conveniently located for the use of displays in show windows. Having receptacles placed within this specified distance allows for easy connection of lighting and other electrical devices that enhance merchandise presentation, thereby improving visibility and aesthetics.

This requirement is particularly important for retail environments where product display plays a critical role in sales. The 18-inch limit strikes a balance between accessibility and safety, preventing the risk of cords and equipment being positioned too far away, which could lead to unsafe practices or damage to the interior of the show window.
