🔍 Key Concepts

• Lockout/Tagout (LOTO) procedures and why absence-of-voltage testing is part of them • The relationship between the source, the disconnecting means, and the actual work location • How to ensure that the exact conductors and components you will touch are verified de‑energized

💭 Think About

• Ask yourself: If you only test at a disconnect or breaker, are you guaranteed that the specific spot where your hands/tools will be is de‑energized? Why or why not? • Think about possible faults like backfeeds, mis‑wiring, or multiple sources. Where would a test most directly confirm that what you are about to touch is truly at zero voltage? • Consider which option best matches the safety principle: "Test as close as practical to where the work will actually be performed."

✅ Before You Answer

• Verify which choice refers to the exact location of the intended work versus just upstream protective devices. • Check which option would still catch hazards such as backfeed or incorrect wiring that might leave the work location energized even if a breaker is open. • Confirm that the selected point of test aligns with standard electrical safety and LOTO best practices (e.g., NFPA 70E concepts), focusing on personal protection at the work site.
