Question 202Electricity & Electronics - QMED

The correct answer is A. The totally enclosed, fan-cooled (TEFC) motor enclosure is designed to prevent the ingress of dust, dirt, and moisture, while using a fan to draw air across the motor to provide cooling. This type of enclosure is well-suited for marine applications where the motor may be exposed to the elements. Based on the illustration EL-0001, option A depicts the TEFC motor enclosure. The other options (B, C, and D) may represent different types of motor enclosures, such as open drip-proof or splash-proof, which are not as well-protected from the marine environment as the TEFC enclosure.
