• A. Ampacity adjustment or correction factors for feeder conductors
• B. Neutral conductor routing
• C. Voltage drop calculations for feeders
• D. Ground fault protection requirements

Answer: (A)

Ampacity adjustment or correction factors for feeder conductors. After you size a feeder to carry the calculated load, this section guides you to adjust that conductor’s ampacity to reflect real-world conditions. The key adjustments come from ambient temperature effects and from the number of current-carrying conductors in a raceway or cable. Temperature adjustments use tables that account for the insulation rating and the actual ambient temperature, which can raise or lower the usable ampacity. The grouping adjustment reduces the allowable ampacity when there are more than three current-carrying conductors sharing a path. The goal is to ensure the feeder’s adjusted ampacity meets or exceeds the calculated load; if it doesn’t, you’d select a larger conductor size or otherwise modify the design. Other topics like neutral routing, voltage drop, or ground-fault protection are handled in different parts of the design process.
