For a 10-unit multifamily dwelling, ___ VA portion of the calculated lighting load is taken at 100% in the general lighting demand.

For a 10-unit multifamily dwelling, ___ VA portion of the calculated lighting load is taken at 100% in the general lighting demand.

• A. first 3,000
• B. 3,001 - 120,000
• C. remainder over 120,000
• D. the total

Answer: (A)

In general lighting demand calculations, the load is treated in tiers. The first portion of the calculated lighting load, up to 3,000 VA, is taken at 100%—no reduction. After that, the remaining load is scaled by demand factors that depend on the total load (and building size). For a 10‑unit multifamily dwelling, that initial 3,000 VA is the portion accounted for at full value in the general lighting demand. The rest of the load is then reduced by the applicable demand factors for the larger ranges. So the correct concept is that the first 3,000 VA are taken at 100%.
