Question 236Electricity & Electronics - 1st Asst/Chief

The correct answer is B) The motor has three-leg protection by thermal overloads. This is the correct answer because in a manual motor starter diagram, the three-leg protection by thermal overloads is the standard configuration to protect the motor from overload conditions. Thermal overloads measure the current flowing through the motor and will trip the starter if the current exceeds a certain threshold, preventing damage to the motor. The other options are incorrect because: A) refers to magnetic overloads, which are less common in manual motor starters; C) and D) mention two-leg protection, which is not the standard configuration for a three-phase motor.
