To determine

List the advantages of the use of two-wire control devices.

Expert Solution & Answer

Explanation of Solution

A two-wire control circuit can be a pressure switch, toggle switch, simple switch, limit switch, float switch, or a thermostat which breaks or makes a connection to a motor through definite on and off positions.

The advantage of two-wire control devices is that the motor is operated (or controlled) by an automatic control device without requiring the presence of a human operator. For example, if the motor is stopped by power failure while the contacts are closed, the two wire control device will not open, that remains in a closed condition. Therefore, the motor can restart when the power is restored.

Conclusion:

Thus, the advantage of the use of two-wire control devices is explained.
