Oxidation
Oxidation is a common issue in electrical repair where metal parts react with air and moisture to form rust or corrosion. This is similar to how a car can rust, but in electrical work, it's particularly important because oxidation can prevent electricity from flowing properly. Technicians often need to identify, clean, or prevent oxidation to keep electrical connections working safely. When you see this term in resumes, it usually refers to someone's experience in diagnosing and fixing problems caused by corroded electrical connections, especially in buildings, vehicles, or equipment maintenance.

Example Interview Questions
Senior Level Questions
Q: How do you develop a preventive maintenance program to address oxidation in electrical systems?
Expected Answer: A senior technician should explain how they create inspection schedules, identify high-risk areas for oxidation, choose appropriate protective measures, and train others on maintenance procedures.
Q: What methods do you use to prevent oxidation in outdoor electrical installations?
Expected Answer: They should discuss weather-proofing techniques, proper sealing methods, selection of corrosion-resistant materials, and regular inspection protocols.
Mid Level Questions
Q: What signs indicate oxidation in electrical connections?
Expected Answer: Should describe visual indicators like green or white deposits on copper, rusty connections, and how to spot potential problems before they cause failures.
Q: How do you properly clean oxidized electrical connections?
Expected Answer: Should explain safe cleaning methods, appropriate cleaning materials, and necessary safety precautions when working with corroded electrical components.
Junior Level Questions
Q: Why is oxidation a problem in electrical systems?
Expected Answer: Should explain that oxidation creates resistance in electrical connections, which can cause heat, power loss, and safety hazards.
Q: What safety precautions do you take when working with oxidized electrical components?
