Abstract
A power cord for a leakage current detection and interruption device including two insulated power supply lines, two leakage current detection lines for detecting a leakage current on the power supply lines, and two conductor wires. The two leakage current detection lines and the two conductor wires are electrically insulated from each other along the length of the power cord but are electrically connected in series to form a detection current path of a leakage current detection module. The leakage current detection and interruption device further includes a detection monitoring module, coupled in series to the detection current path, for detecting an open circuit condition in the detection current path. The device further includes a switch module and a drive module, which can cut off power supply in response to a detected leakage current or open circuit condition in the detection current path.
