Question 44General Subjects - Assistant Engineer

The correct answer is A) Excessive drive belt tension. When a belt-driven reciprocating air compressor has excessive drive belt tension, it can result in an increased current draw from the drive motor. This is because the excessive tension creates additional load on the motor, requiring it to work harder and draw more current to overcome the increased resistance. The other options are incorrect because: B) Insufficient drive belt tension would reduce the load on the motor and decrease the current draw; C) Excessive internal running clearances would not directly impact the current draw; and D) A clogged air intake filter would increase the load on the compressor, but not necessarily the drive motor current draw.
