Q

If a small electric motor has been immersed in salt water, what should be done? Thoroughly rinsed in fresh water and completely dried initially started with reduced voltage

🔍 Key Concepts

• Effects of salt water vs fresh water on electrical equipment • Purpose of rinsing and drying an electric motor after immersion • Risks of applying full voltage immediately to a motor that has been wet

💭 Think About

• Think about what salt deposits and moisture inside the windings might do if you energize the motor too soon. • Consider why someone might choose to rinse with fresh water after salt water immersion—what problem are they trying to solve? • Ask yourself what starting at reduced voltage would change about current flow and potential internal damage if the insulation is still damp.

✅ Before You Answer

• Verify whether salt inside a motor is more or less conductive than clean, dry components. • Consider whether the motor must be completely dry before any attempt to energize it. • Evaluate if starting with reduced voltage meaningfully prevents electrical faults when moisture or residue may still be present.
