🔍 Key Concepts

• electric motor protection devices (overload relays, fuses, breakers) • difference between mechanical faults (valves, unloaders) and electrical faults (power supply, starters) • how the symptom "fails to start" is different from "starts but won’t build pressure"

💭 Think About

• Ask yourself: which option would most directly interrupt electrical power to the motor so that it cannot start at all? • Which faults involving valves or unloaders would more likely let the motor run but affect pressure or loading rather than completely preventing starting? • Think about what device is designed specifically to open when the motor draws too much current or overheats.

✅ Before You Answer

• Identify which choice is an electrical protection device rather than a mechanical air-end problem. • Decide which problems would usually result in no motor rotation versus poor compression or low pressure. • Before choosing, mentally picture the starter circuit and what must be closed for the motor to receive power.
