RCD (Residual Current Device), or residual-current circuit breaker (RCBO), is a device that instantly breaks an electric circuit to prevent serious harm from an ongoing electric shock. What does an RCD (Residual Current Device) do - An RCD is a sensitive safety device that switches off electricity automatically if there is a fault. An RCD is designed to protect against the risks of electrocution and fire caused by earth faults. For example, if you cut through the cable when mowing the lawn and accidentally touched the exposed live wires or a faulty appliance overheats causing electric current to flow to earth. How Does RCD (Residual Current Device) works - These electrical wiring devices are designed to quickly and automatically disconnect a circuit when it detects that the electric current is not balanced between the energized (line) conductor(s) and the return (neutral) conductor. Under normal circumstances, these two wires are expected to carry matching currents, and any difference can indicate a short circuit or other electrical anomaly is present, such as leakage. Leakage can indicate a shock hazard (or shock in progress) which is a potential danger to a person. Current leakage can result in harm or death due to electric shock, especially if the leaking electric current passes through the torso of a human. A current of around 30 mA (0.030 amperes) is potentially sufficient to cause cardiac arrest or serious harm if it persists for more than a small fraction of a second. RCDs are designed to disconnect the conducting wires quickly enough to prevent serious injury from such shocks, commonly described as the RCD being "tripped". Disadvantages of RCD (Residual Current Device) - RCD does not provide protection against unexpected or dangerously high current (called spikes or surges) when current is flowing in the usual wires in the circuit, therefore it cannot replace a fuse or protect against overheating or fire risk due to overcurrent (overload) or short circuits if the fault does not lead to current leakage. RCD (Residual Current Device) worldwide - In the United States and Canada, the device is more commonly known as a ground fault circuit interrupter (GFCI), ground fault interrupter (GFI) or an appliance leakage current interrupter (ALCI). In the United Kingdom, these are better known by their initials RCD, and a combined RCD+MCB (miniature circuit breaker) is known as a RCBO (residual-current circuit breaker with overcurrent protection). In Australia, they are sometimes known as safety switches or an RCD. An earth leakage circuit breaker (ELCB) may be a residual-current device, although an older type of voltage-operated earth leakage circuit breaker also exists. In German-speaking countries the device is sometimes known as FI where the F stands for fault (Fehler) and I for the symbol that represents electric current. =========================================== Dear friends, support this channel http://hrvoje3d.com/support/ =========================================== Subscribe and give a support :) ✔ Subscribe https://www.youtube.com/user/chrvoje1 ✔ WEB http://www.hrvoje3d.com/ ✔ FACEBOOK https://www.facebook.com/Chrvoje1-engineering-606909579495110/ https://www.facebook.com/profile.php?id=100015365768626 ✔ TWITTER https://twitter.com/chrvoje1 ============================================= Thanks For Watching.......
