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

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

• A. 1200 VA
• B. 1600 VA
• C. 2400 VA
• D. 3200 VA

Answer: (C)

The minimum calculated feeder load for show window lighting can be determined using guidelines set by the National Electrical Code (NEC). Show windows are often treated as general lighting, and the minimum load calculation typically follows a specific design criterion. In this case, the common practice is to calculate the feeder load based on an assumption of 200 VA per linear foot of display lighting. For 12 feet of show window lighting, this calculation would be: 12 feet x 200 VA/foot = 2400 VA. This shows that the minimum calculated feeder load for this application, taking into account the standard assumptions for adequate lighting in show windows, amounts to 2400 VA. This ensures that the lighting will be sufficient to illuminate the window display effectively while adhering to electrical safety standards.
