Quizplus · Accepted Answer

A sump pump is commonly operated by an automatic control system that turns it on when the water level in the sump pit rises above a certain level, and turns it off when the water level drops below that level. The other options (stairway luminaire, entrance luminaire, and exterior luminaires) are lighting fixtures that are typically controlled by a manual switch or a timer, rather than an automatic control system.
