Structural addition requirements reference which sections?

Structural addition requirements reference which sections?

• A. 220.12
• B. 220.14
• C. Both A and B
• D. Neither A nor B

Answer: (A)

When a structure is being added to, you must re-calculate the electrical load to size the service properly using the dwelling unit load calculation method. Section 220.12 provides that method for dwelling unit general lighting loads (and related receptacle and fixed loads) including additions to an existing dwelling. It’s the primary reference used for calculating the loads associated with structural additions. Section 220.14 covers other loads beyond the standard dwelling-unit calculations and isn’t the reference used for structual additions. Therefore, the correct reference is Section 220.12.
