Abstract

A protection circuit for electric equipment includes a sensor, a driver and an alarm. The sensor is connected between a neutral wire and a ground wire of a AC power-source, and connected to the relay. The driver is connected between the AC power-source and the electric equipment, and connected to the alarm. When the sensor senses the live wire and the neutral wire are connected contrary, the sensor make the driver cut off the connection between the live wire and the electric equipment and cut off the connection between the neutral wire and the electric equipment. The protection circuit can protect the electric equipment from being burned, when the live wire and the neutral wire are connected contrary.
