Plug the Breaker Buddy in to two separate outlets and if the green light comes on you are on separate circuits. Helps avoid tripping breakers on dual cord machines or when using accessories like an (RX20) or separate electric heater.
No light means on same breaker
Dimly lit means different breakers but same phase.
Fully lit means different breakers on different phases.
