How to Use a Breaker Locator Tool

Quick answer

To use a breaker locator tool, first turn off the suspected circuit breaker. Plug the transmitter into the outlet and turn it on. Then, use the receiver to scan the breaker box. When you hear a signal, you've found the right breaker. Always ensure power is off before handling breakers.
