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

🔍 Key Concepts

• Safe procedure for working on energized electrical equipment • Purpose of a motor starter "stop" position in testing or maintenance • Correct sequence when using a multimeter as a voltmeter on a three‑phase circuit

💭 Think About

• Before putting meter leads on any part of a live circuit, what condition should the equipment and controls be in? • Which choice directly relates to safety and proper isolation, and which choices assume the circuit is already being measured? • Think about what step must logically come before placing meter leads on either the top or bottom ends of the fuses.

✅ Before You Answer

• Personal and equipment safety: what control positions minimize risk before testing? • Verify whether the motor needs to be under load for a simple blown‑fuse check with a voltmeter • Confirm that you do not put meter leads on a circuit until the starter/control is in the proper position

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

place the leads across the bottom ends of the fuses

make sure the motor is operating at full load to guard against a false reading

place the leads across the "hot" ends of the fuses

place the starter in the "stop" position
