Feeder conductors for new restaurants are not required to be of ___ ampacity than the service-entrance conductors.

• A. lesser
• B. greater
• C. equal
• D. not specified

Answer: (B)

The main idea here is how ampacity is used when sizing feeders versus the service-entrance conductors. The service-entrance conductors are sized to carry the overall calculated demand for the building, while feeders are sized to supply the specific loads downstream (with appropriate demand factors). For new restaurants, the design practice often does not require feeders to be larger in ampacity than the service-entrance conductors; the service-entrance is already sized for the building’s total demand, and feeders can be equal to or not exceed that ampacity as long as the calculated loads and protection are correct. Therefore, the blank should be filled with greater, since the statement says feeders are not required to be of greater ampacity than the service-entrance conductors.
