GFCI - A Ground Fault Circuit Interrupter (GFCI) or Residual Current Device (RCD) is a
device that shuts off an electric power circuit when it detects that current is flowing
along an unintended path, such as through water or a person.
RCD - Residual Current Device (RCD) or a Ground Fault Circuit Interrupter (GFCI) is a
device that shuts off an electric power circuit when it detects that current is flowing
along an unintended path, such as through water or a person.
