This document describes a project to remotely monitor and control a residual current circuit breaker (RCCB) using mobile phone instant messaging. The project aims to allow homeowners to receive notifications of RCCB trips due to leakage currents and remotely reset the RCCB once safe conditions are detected. It is divided into modules for the main controllers, auxiliary drivers, and power supply. Experimental results validated the proposed functions and operations, including sending notifications of power outages or trips and allowing or preventing resets based on residual current levels. The project proposes a promising solution for remote RCCB control that could be applied to household electrical systems in the near future.
