Question 280Electricity & Electronics - Assistant Engineer

The correct answer is D. The illustration EL-0179 represents a magnetic reversing or two-speed motor starter, which is correctly identified as option D. This type of motor starter is commonly used in marine applications to control the direction and speed of electric motors, such as those used for propulsion or auxiliary systems on Coast Guard vessels. The other options (A, B, and C) do not correctly depict a magnetic reversing or two-speed motor starter, as they represent different types of electrical components or circuit diagrams.
