🔍 Key Concepts

• Purpose of coating on electrical leads and windings (insulation, moisture protection, heat resistance) • Difference between paint that conducts heat vs. material that must not conduct electricity • Typical treatment of motor windings and leads in marine service (think about insulation, not metal protection)

💭 Think About

• Ask yourself: Are we trying to improve electrical insulation, protect against corrosion, or radiate heat from the motor? • Which option sounds like something used specifically on electrical insulation and windings, rather than on metal surfaces or structures? • If electricity must NOT leak to the motor frame or other parts, what kind of coating makes the most sense for covering the leads and insulation?

✅ Before You Answer

• Verify which choices are metals or paints for metal surfaces versus materials used on electrical components. • Check which option clearly indicates an insulating purpose rather than heat conduction or corrosion protection. • Confirm that your choice would improve dielectric (insulating) strength of the leads instead of risking a conductive path.
