Quizplus · Accepted Answer

Agricultural buildings can have high levels of dust, moisture, and corrosive particles that can damage motors and other rotating electrical machinery. Therefore, it is important for these machines to be designed to minimize their entrance. Ambient static charges and lightning are not significant concerns in relation to motor protection in agricultural buildings. Grain/seed dust is a potential hazard but is addressed specifically in other sections of the electrical code.
