The residual current device in the home s electrical distribution box only has one circuit breaker
It is an electrical device curated to protect people as well as equipment from two major electrical hazards, namely earth leakage current and overcurrent. This RCBO combines the functions of RCD (Residual Current Device) and an MCB (Miniature Circuit Breaker), put in a. A residual-current device (RCD), residual-current circuit breaker (RCCB) or ground fault circuit interrupter (GFCI) is an electrical safety device, more specifically a form of Earth-leakage circuit breaker, that interrupts an electrical circuit when the current passing through line and neutral. Residual current is the small amount of electrical current that flows through an unintended path, such as a human body or the ground, instead of the intended circuit. A. An RCD, or residual current device, is a life-saving device which is designed to prevent you from getting a fatal electric shock if you touch something live, such as a bare wire.
