Electrical arc protection using a trip jumper

A system comprising:

• an electrical device;
• a line cord comprising a plurality of electrical wires and a power plug, wherein the line cord and the plurality of electrical wires connect the electrical device to the power plug, wherein the power plug comprises a plurality of plug power contacts, each of the plurality of plug power contacts coupled to a respective electrical wire included in the plurality of electrical wires of the line cord, and wherein the power plug further comprises a plug trip jumper having a first and a second jumper contact electrically coupled to each other to permit a current to flow through the plug trip jumper, and wherein each of the first and second jumper contacts comprises a respective electrically conductive tip and a respective electrically non-conductive region;
• and
• wherein each of the first and second jumper contacts are configured to make a trip connection, during a plugging action with the power plug and a power receptacle, with respective mating receptacle trip contacts included in the power receptacle;
• wherein, the respective electrically conductive tip of each of the first and second jumper contacts is configured to make the trip connection with the respective mating receptacle trip contact;
• wherein at least one of the first and second jumper contacts is further configured such that, when the power plug is fully connected to the power receptacle, the respective electrically conductive tip does not make the trip connection with the respective mating receptacle trip contact and the respective electrically non-conductive region is placed in contact with the respective mating receptacle trip contact, thereby preventing the trip current through the plug trip jumper;
• wherein the trip connection permits a trip current through the plug trip jumper when the first and second jumper contacts make the trip connection with the mating receptacle trip contacts and at least one receptacle power contact, included in the power receptacle, is connected to electrical power provided by a power source;
• and
• wherein the trip current causes disconnection, from the electrical power, of the at least one receptacle power contact among the at least one receptacle power contact connected to the electrical power.
