For show window lighting load calculations, which value shall be included for this load?

• A. 200 VA per linear ft.
• B. 120 VA per outlet
• C. 180 VA per linear ft.
• D. 280 VA per outlet

Answer: (A)

In show window load calculations, a fixed load is used per length of the window rather than per fixture or outlet. This standardizes the expected lighting load for display areas. The value to use is 200 VA for every linear foot of show window. So multiply the window length in feet by 200 to get the VA load to add to the overall lighting calculation. This approach reflects the fact that storefront displays typically have multiple lights spread across the window, and the code provides this per-foot figure to simplify sizing. For example, a 15-foot window adds 3,000 VA (15 x 200). The other options rely on per-outlet or different per-foot figures that don’t match this standard method.
