Abstract
A protective arrangement for an electrical device energized from an alternating current power supply which de-energizes the electrical device when undesirable conditions, develop within the electrical device. The protective arrangement, when provided for an electrical device having protection for undesirable leakage currents in the power cord supplying to electrical device, utilizes the same circuit interrupting device to de-energize the electrical device upon the occurrence of an undesirable condition, other than a leakage current, within the device, or upon the occurrence of an undesirable leakage current in the power cord supplying the electrical device.
