  • Record motor nameplate voltage, frequency, phase, and full-load current
  • Confirm the installed starter or drive matches the intended motor application
  • Confirm overload device type and setting basis
  • Confirm the overload setting is not a guess copied from a different motor
  • Confirm the motor connection arrangement matches the nameplate or wiring diagram
  • Confirm enclosure/environment suitability has been reviewed

Overload setting should be based on the actual motor application basis and the selected protection scheme, not on casual field assumption.
