Residual current devices (RCDs) are electrical safety devices designed to quickly disconnect a circuit in the event of a fault. The installation of RCDs involves connecting them to the electrical distribution board or consumer unit, where they can monitor the flow of electricity in the circuit. They are typically installed on the incoming mains supply and can also be installed on individual circuits for added protection. It is important to have RCDs installed by a qualified electrician to ensure they are correctly wired and functioning properly to provide the necessary protection against electric shock and fire hazards. **
