The minimum calculated feeder load for 12 feet of show window lighting is _________.

To determine the minimum calculated feeder load for show window lighting, it's essential to understand the relevant electrical codes and calculations. Show windows typically require a certain amount of lighting based on their length to ensure adequate illumination for display purposes.

For show window lighting, the National Electrical Code (NEC) detailed requirements generally provide a base calculation. This typically involves calculating the load based on the length of the window in feet, and the VA (volt-amps) load per foot that the lighting calls for. In various applications, the typical value is around 200 VA per foot.

For a 12-foot show window, this would yield the following calculation:

12 feet x 200 VA/foot = 2400 VA

This calculation aligns with the regulations and indicates that the minimum calculated feeder load for lighting in show windows needs to account for this substantial requirement, ensuring that enough power is provisioned for optimal lighting in display areas. Therefore, the answer of 2400 VA reflects the necessary load to adequately illuminate a 12-foot show window according to the established standards.
