| As shown in the illustrated motor controller, assuming that the distribution system is an ungrounded system (common equipment grounding conductor insulated from the source), what faulty controller operation could be the result of the two accidental grounds as shown? |
| A) failure of the overload relay to trip the motor in the event of a motor overload |
| B) premature tripping of the motor on overload even though motor current draws are in the normal range |
| C) mysterious startup of the motor without first depressing the start button |
| D) controller exhibiting behavior appropriate to low voltage release rather than low voltage protection |
