Question: how to calculate the electrical load in a commercial building?
Answer: A commercial occupancy has a receptacle load of 15,300 volt-amperes and a fixed multioutlet assembly load of 4,860. The total receptacle load is 20,160 volt-amperes. First, subtract 10,000 from the total receptacle load (20,160 – 10,000 = 10,160). Next, multiply the remainder by 50% (10,160 × 50% = 5,080).
