Using the NEC 2020 220.82 optional method, what is the calculated service load for a 1,500 sq ft one-family dwelling with two small-appliance circuits, one laundry circuit, an 8,000 VA range, a 5,000 VA dryer, a 4,500 VA water heater, a 1,200 VA dishwasher, and 4,000 VA of air conditioning (no electric heat)?

21,080 VA (87.8 A at 240 V), so a 100-ampere service meets the calculated load 27,700 VA (115.4 A at 240 V), so a 125-ampere service is the minimum 31,700 VA (132.1 A at 240 V), so a 150-ampere service is the minimum 15,000 VA (62.5 A at 240 V), so a 60-ampere service is permitted
