Requirements for structural addition include which of the following?

Explanation:
When you add to a structure, the total electrical demand changes, so you must redo the dwelling’s load calculation to size the service, feeders, and overcurrent protection correctly. The part of the code that specifically applies to structural additions is the section that requires including the added load in the dwelling-load calculation, ensuring the service is adequate for the new total. This step is essential for safe, code-compliant sizing after an addition. Other code provisions address different scenarios not tied to additions, so they don’t cover the required sizing for a structural addition.
