What is the total VA required for a 50' show window using the VA/linear foot method?

To determine the total VA (volt-amperes) required for a show window using the VA/linear foot method, it is essential to understand the standard calculation for show windows. Typically, the NEC code mandates 250 VA per linear foot for show windows in commercial settings.

For a 50-foot show window, the calculation would be as follows:

50 feet x 250 VA/foot = 12,500 VA.

This results in a total of 12,500 VA required for the lighting in the show window. Therefore, the correct answer aligns perfectly with the standard method of calculation and the code requirements, making it the right choice for this question.
