To check the three line fuses protecting a three-phase motor using a multimeter set up as a voltmeter, what should be done FIRST?

Correct Answer: Option B — place the starter in the 'stop' position

Safety protocols require isolating the circuit before testing. Placing the starter in the 'stop' position ensures the motor is de-energized, preventing accidental operation or electrical hazards to the technician. Once isolated, voltage measurements can safely confirm the integrity of the fuses and the supply side of the circuit.
