摘要：
The present invention concerns an electrical power cord having an illuminated connector including a circuit to protect a power and/or ground continuity indicator incorporated into the connector. The connector is illuminated if it is connected to an active power source with or without a functioning ground conductor, depending upon the electrical configuration within the connector. The circuit is designed to shield the indicator during an excessive voltage test in accordance with the UL specification for power cords.
