General lighting loads for non-dwelling occupancies are detailed in which NEC resource?
Correct Answer:
NEC Table 220.42(A)
Explanation:
General lighting loads for non-dwelling occupancies come from NEC Table 220.42(A). This table lists the lighting unit load in VA per square foot for different types of nonresidential occupancies. To size feeders or a service, you multiply the building area by the unit load from the table for the specific occupancy, then apply any applicable demand factors and add to other loads as needed. The other sections referenced in the choices relate to different types of loads or parts of the code (such as motors or other calculations) and do not provide the general lighting unit loads for non-dwelling occupancies.
