<p>An electrical connection safety apparatus that eliminates the risk of fire or electric shock associated with current overload faults in electrical systems. The apparatus senses or detects the electrical current rating of electrical appliances or electrical cords or connectors that are plugged into electrical outlets (18, 16a, 16b), and disconnects power whenever the current rating is exceeded. Current rating is indicated by a preset current threshold for the applicance or by a detectable feature associated with an electrical connnector (20, 22, 24a, 24b, 26, 28). Circuitry monitors the load current delivered to the appliance or receptacle (16a, 16b) and connector and compares the load current to detected current rating. When a current overload occurs, power to the appliance or receptacle and connector is disconnected (42).</p> |
