Question:

A single family dwelling unit has a branch circuit lighting load of 1,90,000 VA. What is the demand load of a dwelling unit after the demand factor applied?

A
61450

Explaination

Demand factor for first 3000 is 100% so = 3000 VA

Demand factor for load Between 3000 to 120000VA is 35% = 117000 x 0.35 = 40,950

Demand factor for load above 120000VA is 25% = 70000 x 0.25 = 17500

Total demand load= 3000 + 40950 + 17500 = 61450.
