When calculating the feeder load for a multi-family dwelling, what is the maximum load that should be considered for general lighting calculations?

In the context of calculating feeder loads for multi-family dwellings, the maximum load considered for general lighting calculations is typically set by the National Electrical Code (NEC) guidelines. According to these guidelines, for multi-family dwellings, the load for general lighting is usually calculated at 3 VA per square foot. This calculation is crucial because it ensures that the electrical system is adequately sized to handle the expected load under various occupancy scenarios.

The option that aligns with the NEC guidelines for multi-family dwelling lighting calculations is 120,000 VA. This number represents a balance between the needs for sufficient lighting, safety, and efficiency. It accounts for the average square footage of multi-family units and provides a reasonable estimate for the total load that should be supported by the electrical service.

Understanding these calculations enables electrical professionals to design systems that can handle the load effectively, avoiding potential overloads and ensuring compliance with electrical codes.
