Chiller Service Engineer Interview Questions and Answers

The human resistance of 0.5amps should be set less than 30ma for 0.1 second.

• The question is asking about setting the current limit for a chiller service engineer.

• The engineer needs to ensure that the current limit is set below 30ma for 0.1 second to avoid harm to humans.

• The human resistance of 0.5amps should be taken into consideration when setting the current limit.

There is no single best chiller company as it depends on various factors such as specific requirements, budget, and location.

• The best chiller company may vary depending on the specific needs of the customer.

• Factors to consider include the type of chiller required (air-cooled, water-cooled, etc.), capacity, energy efficiency, and maintenance requirements.

• Some well-known chiller companies include Trane, Carrier, York, Daikin, and Johnson Controls.

ELCB rating and time depend on the load and application.

• ELCB rating should be selected based on the maximum current that can flow through the circuit.

• The time rating should be selected based on the type of load and the sensitivity of the equipment.

• For example, a 30mA ELCB with a time rating of 0.1 seconds is suitable for residential applications.

• For industrial applications, a higher rating ELCB with a longer time rating may be required.

• Consulting the manufacturer's specificat...read more
