Patent number: 9893455Abstract: A plug comprises power contacts and a plug trip contact. During a plugging action between the plug and a receptacle, the plug trip contact makes a trip connection with mating contacts in the receptacle. Electrical power to the receptacle allows a current through the trip connection, which causes disconnection of the power to the receptacle. A receptacle comprises receptacle power contacts and receptacle trip contacts. During a plugging action between the receptacle and a plug, trip contacts in the receptacle makes a trip connection with a mating contact in the plug. Electrical power to the receptacle allows a current through the trip connection, which can cause disconnection of the power to the receptacle. The receptacle can be included in an enclosure having a trip breaker with a trip mechanism. An electrical system can have an electrical device with a line cord connected to a plug having the trip contact.Type: GrantFiled: November 1, 2016Date of Patent: February 13, 2018Assignee: International Business Machines CorporationInventors: William L.
