The demand lighting load for a 20,000 ft² motel with no dining room or ballroom is what?

To determine the demand lighting load for a 20,000 square foot motel without a dining room or ballroom, it is essential to refer to the guidelines set out in the National Electrical Code (NEC). According to NEC calculations for commercial facilities, the demand for general lighting can typically be estimated based on the square footage of the area.

For hotels and motels, a common approach is to apply a demand factor that results from multiplying the area by a specific VA (volt-ampere) demand per square foot. This value is determined through NEC guidelines which often list a demand of 0.9 VA per square foot for lighting in certain types of establishments. Thus, for a 20,000 square foot motel:

20,000 sq. ft. x 0.9 VA/sq. ft. = 18,000 VA.

This calculation accurately reflects the expected demand lighting load for the motel given its size and the absence of additional high-load areas such as a dining room or ballroom.

Choosing 18,000 VA as the answer is correct because it corresponds directly to the NEC demand calculations for motel lighting loads, ensuring that electrical designs remain efficient while also maintaining safety. This selection aligns with the requirements and expectations for lodging establishments, which helps
