Which of the listed procedures is the best way to tell if a motor has become overloaded?

Question 1 of 27070

Which of the listed procedures is the best way to tell if a motor has become overloaded?

🔍 Key Concepts

• Motor full-load current (FLC) on the nameplate and what it represents • Relationship between electrical current and mechanical/electrical load on a motor • Why relying on temperature or visible damage is not a safe or precise diagnostic method

💭 Think About

• Which method gives you an objective, measurable comparison against the motor’s designed operating limits? • At what point in the overload process do heat and smoke appear compared with an increase in current? Early warning or late warning? • What is the purpose of overload (O/L) relays and how are they supposed to operate in relation to motor current?

✅ Before You Answer

• Check which option uses the motor’s nameplate data (full-load current rating) for comparison. • Consider which procedure would indicate an overload before damage occurs, not after. • Verify which choice describes a standard, recommended practice in electrical troubleshooting and preventive maintenance.

Which of the listed procedures is the best way to tell if a motor has become overloaded?

Measure the current flow and compare it with the motor full load current flow as shown on the nameplate.

Feel the motor and judge by the temperature.

Watch for telltale signs of smoke coming from the motor.

Periodic opening of the O/L relay coil.
