1) Diagram a Hand/Off/Auto switch connected to a temperature switch, controlling a three-phase induction motor.

- When the selector is in Hand, the motor will run.
- There will be a green pilot light when the motor is running.
- There will also be a red pilot light indicating there is power on the circuit. The red light will de-energize while the motor is running.
- When the selector is switched to Auto, the temperature switch will control the operation. The temperature switch is normally open.

Final answer:

In engineering at a college level, an explanation was provided on how a Hand/Off/Auto switch connected to a temperature switch operates control of a three-phase induction motor.


Explanation:

Hand/Off/Auto Switch Connected to a Temperature Switch Controlling a Three-Phase Induction Motor:

  1. When the selector is in Hand, the motor runs with a green pilot light indicating operation and a red pilot light showing power, which de-energizes while the motor is running.
  2. Switching to Auto enables the temperature switch to control operation as it is normally open, allowing automated functionality.
