What is the load for 55' of show window using the linear foot method?

• A. 10,000VA
• B. 12,000VA
• C. 13,750VA
• D. 9,500VA

Answer: (C)

To determine the load for a 55-foot show window using the linear foot method, it's essential to understand how the linear foot method calculates electrical load for display lighting. Generally, the load for show windows is calculated based on the length of the window, with a standard load value per linear foot.

In this case, the value typically used for show windows is 250 VA per linear foot. Therefore, to calculate the total load for a 55-foot show window, you would multiply 250 VA by 55 feet:

[

250 , \text{VA/foot} \times 55 , \text{feet} = 13,750 , \text{VA}

]

This calculation confirms that the total load for a 55-foot show window comes out to 13,750 VA, making it the correct choice. This method considers the need for adequate lighting to showcase merchandise effectively, hence the higher load compared to other uses such as general lighting or standard outlet loads.

Understanding this calculation process is crucial for electrical design in commercial spaces, as it ensures that systems are adequately designed to handle the anticipated loads safely and effectively.
