Question 59Electricity & Electronics - 1st Asst/Chief

The correct answer is A) contactors G2 and S1 pulled in; contactors G1 and S2 dropped out. To secure #1 M/E and set up #2 M/E diesel-generator to supply both propulsion motors, the contactors need to be configured such that the power from #2 M/E is routed to both propulsion motors. This is achieved by pulling in contactors G2 and S1, which connect #2 M/E to the propulsion motors, while dropping out contactors G1 and S2, which would have connected #1 M/E to the propulsion motors. The other options are incorrect because they do not correctly route the power from the active #2 M/E diesel-generator to both propulsion motors.
