Aux 2 Unit 8 Quiz 3

Correct Answer:
B) The cut-out must be manually reset to resume operation

Explanation:
Once the high pressure cut-out is triggered, most systems require a manual reset to ensure that the operator investigates and addresses the cause of the high pressure condition before restarting.

Correct Answer:
C) It stops the compressor when the discharge pressure exceeds a set limit

Explanation:
The high pressure cut-out monitors the pressure in the discharge line and stops the compressor when the pressure goes beyond the set safe threshold, preventing potential damage to the system.

Correct Answer:
C) The discharge line of the compressor

Explanation:
The high pressure cut-out is installed on the discharge line to monitor and control the pressure level, ensuring it does not exceed safe operational limits.

Correct Answer:
B) To prevent potential damage to the condenser

Explanation:
The high pressure cut-out prevents excessive pressure that could lead to damage or failure of the condenser, protecting the system's integrity.

Correct Answer:
B) Blockage or insufficient airflow in the condenser

Explanation:
Blockages or poor airflow through the condenser can cause heat to build up, leading to high pressure in the discharge line and triggering the high pressure cut-out.

Correct Answer:
B) To protect the compressor from damage due to excessive discharge pressure

Explanation:
The high pressure cut-out is designed to prevent damage to the compressor and other components by stopping the system when the discharge pressure exceeds safe operational limits.
