Why it worked
The video provides a practical and visual demonstration of a common household problem (identifying circuit breakers) and offers a clear solution using a specific tool. The "shop in bio" call to action, combined with the utility of the tool, likely drove engagement.
Summary
This video demonstrates the Klein Tools ET310, a voltage tester used to identify which circuit breaker corresponds to a specific outlet. It also shows how the tool can test GFCI outlets for safety and verify correct plug wiring.
