RCD And Work Of RCD
An RCD (residual current device) is a life-saving device that prevents you from receiving a lethal electric shock if you come into contact with something live, such as a bare wire. It can also guard against electrical fires to some extent. Ordinary fuses and circuit breakers cannot give the same level of personal safety as RCDs. Types of RCD- 1. Fixed RCDs 2. Socket-Outlet RCDs 3. Portable RCDs What is work of RCD? An RCD is a sensitive safety device that immediately shuts off electricity if it detects a problem. The purpose of an RCD is to protect against electrocution and fire caused by earth faults. For instance, if you accidently cut through the cable while mowing the grass and touched the exposed live wires, or if a malfunctioning item overheats, causing electric current to flow to earth. Working of RCD: The electric current running through one or more circuits protected by an RCD is constantly monitored. If the RCD detects electricity travelling in an unforeseen direction,
