For each farm building or load supplied by how many branch circuits is the load computed using the demand factors of Table 220.102(B)?

For each farm building or load supplied by how many branch circuits is the load computed using the demand factors of Table 220.102(B)?

• A. one
• B. two
• C. three
• D. four

Answer: (B)

When sizing loads for a farm building that is fed by more than one branch circuit, the NEC uses a special set of demand factors in Table 220.102(B). This table is applied to the load based on two branch circuits, reflecting the common practice of splitting the service between two feeders and recognizing that not all equipment will operate at full load simultaneously. So, the load is calculated using the demand factors for two branch circuits. If more than two circuits are involved, the table has guidance for those situations as well, but the fundamental case the question asks about is two circuits.
