Which term refers to residential structures located on agricultural land?

• A. Farm dwelling units
• B. Farm buildings, NOT dwelling units
• C. Combining loads
• D. Article 225 of the National Electrical Code

Answer: (A)

Farm dwelling units are the residential structures located on agricultural land. The term is used to distinguish living quarters on a farm from non-residential farm buildings like barns or storage sheds. This distinction matters in electrical work because a dwelling on a farm is treated as a residence for purposes of service, feeders, and general electrical requirements, while farm buildings that aren’t dwellings follow different, non-residential rules. The other options don’t describe a type of structure: farm buildings refer to non-residential farm structures, combining loads is a load-calculation concept, and Article 225 is a code article, not a term for the structure on the land.
