🔍 Key Concepts

• Electrical equipment cleaning practices and safety • Effects of high-pressure air on motor windings and insulation • Sources of damage or future faults in electric motors

💭 Think About

• Think about what long-term damage high-pressure air could cause inside a motor, not just what it does to the surface dirt. • Which option describes something that could directly lead to short circuits or insulation failure later on? • Which choices are more about personal protective equipment or housekeeping, rather than actual damage to the motor or controller equipment?

✅ Before You Answer

• Identify which option involves physical damage to insulation rather than just drying or cleaning it. • Consider which effect could cause hidden, hard-to-detect damage inside the motor windings. • Eliminate choices that focus mainly on inconvenience or extra work, not actual equipment safety.
