To determine the increased risk of electroshock, as electrical contractors in Perth, we consider electrical equipment (e.g.,is the electrical apparatus Class 1, exposed conductor parts), and external influences (e.g., exposure to elements, vibrations, production line, and the connection with the supply). These types of RCDs protect the circuit from overload, as well as earth leakage faults; therefore called an RCBO. Circuit breakers are designed to protect a circuit from overloading or short circuit while an RCD is designed to protect a person. Within a commercial and industrial environment, RCDs can look quite different to those installed in a residential environment.
