Cathodic Protection Tester Practice Exam

When servicing a rectifier, which of the following practices should be avoided?

1. Test the case for voltage before contacting

2. Listen for unusual noises

3. Smell for unusual odors

4. Ignore any visual indicators

The correct answer is: Ignore any visual indicators

When servicing a rectifier, it is vital to maintain safety and awareness of potential hazards. Ignoring any visual indicators during the servicing process can lead to undetected issues that might pose risks, such as overheating components or signs of damage, corrosion, or leaks. Visual indicators are crucial because they can signal malfunctions that wouldn't be apparent through sound or smell alone, such as burnt components or moisture accumulation, both of which could lead to severe equipment failure or electrical hazards. Being attentive to visual signs allows a technician to make informed decisions about the condition of the rectifier before proceeding with repairs or adjustments. Therefore, recognizing and addressing these indicators is a fundamental practice for safe and effective servicing.
