Definition of RCD

RCD or Residual Current Device is an electrical instrument whose prime function is to cut the connection when a short circuit is being spotted. When a short circuit and leakage is being found, it cuts the connection from the spotted area of electrocution and electrical fire with the electrical devices. Thus the area is being separated and can’t harm anything else.
