How to Answer: Outline a clear, step-by-step protocol that includes immediately shutting off power to the affected area, conducting a thorough inspection to identify the source of the issue, and following all relevant safety guidelines and local codes. Mention the importance of using specialized tools for detecting electrical faults and consulting with or referring the issue to a licensed electrician if needed.

Example: “Safety is always the top priority when dealing with suspected electrical issues in pool systems. My first step is to turn off the power supply to the pool equipment to prevent any accidents. Then, I would inspect the wiring, connections, and equipment for obvious signs of damage or wear.

If the issue isn’t immediately clear or seems complex, I rely on my multimeter to check for continuity and voltage, which helps pinpoint the problem without unnecessary guesswork. For any issues beyond my scope or requiring significant electrical work, I coordinate with a certified electrician to ensure everything is handled correctly and safely. This approach minimizes risks and ensures the problem is resolved efficiently and professionally.”
