Final answer:
The general lighting and receptacle load for a 3,000 sq ft dwelling with three small appliance branch circuits and one laundry branch circuit is 15,000 VA.option A.
Step-by-step explanation:
The general lighting and receptacle load for a 3,000 sq ft dwelling can be calculated by using the National Electrical Code (NEC) guidelines. According to the NEC, for a dwelling unit of this size, the general lighting load is determined by multiplying the square footage by 3 VA per square foot. So, in this case, the general lighting load would be 3000 sq ft x 3 VA/sq ft = 9000 VA.
As for the receptacle load, the NEC guidelines state that for a 3,000 sq ft dwelling, you need to provide a minimum of 3 small appliance branch circuits (each with a load of 1500 VA) and 1 laundry branch circuit (with a load of 1500 VA). So, the receptacle load would be (3 x 1500 VA) + 1500 VA = 6000 VA.
Therefore, the total lighting and receptacle load for the given dwelling would be 9000 VA + 6000 VA = 15000 VA.
