Question 210Electricity & Electronics - QMED

The correct answer is C) explosion proof. Electric motors that are used in hazardous environments, such as those with flammable gases or vapors, must be designed and constructed to be explosion proof. This means the motor's enclosure is designed to withstand an internal explosion and prevent the ignition of the surrounding flammable atmosphere. This is a safety requirement specified by electrical codes and regulations for the use of electrical equipment in hazardous locations. The other answer choices do not specifically address the requirement for explosion-proof design in hazardous environments. Overload proof, ground proof, and short proof are important safety features, but they do not necessarily make a motor suitable for use in explosive atmospheres.
