Fluke ST240+ RCD Socket Tester is Easy to Use
The bright LEDs and included chart on this device can help you quickly and easily check the wiring of an Australian outlet socket. You can also identify several common wiring errors, like reversed phase and neutral wires, or an open ground.
The ST240+ also has a unique alarm that goes off anytime voltage is detected. This way, you can save time when trying to find which circuit breaker is connected to which outlet. You just need to plug the socket tester in, walk to the circuit breaker panel, and listen for the beeper to turn off or on as they flip the breakers. Once it does, you have found the correct breaker. Time and trips saved.
