The Core Issue: Assuming a circuit is dead because a breaker was flipped is a leading cause of electrical fatalities.
The Lesson: Always use the “Prove-Test-Prove” method. Test your meter on a known live source, test the circuit you are about to work on to verify it’s dead, and then test the known live source again to ensure your meter didn’t fail.
Actionable Takeaway: A circuit is live until your meter proves it isn’t. Never skip the verification step.
