As shown in the illustration, which of the following pieces of equipment is fed with the three conductor cable with the individual conductors having the smallest cross-sectional area? EL-0165

Correct Answer: Option B — Sewage Treatment Plant

Electrical load analysis dictates that smaller auxiliary equipment, such as a sewage treatment plant, typically draws significantly less current than heavy-duty machinery like cargo pumps or cooling pumps. Consequently, the circuit feeding the sewage plant requires conductors with the smallest cross-sectional area to meet the specific load demand.
