The present invention is directed, in part, to electrical components and methods of use associated with such components. In particular, the invention relates to an electrical device and improved method of back feeding energy generated from alternative energy devices such as solar panels, wind turbines, fuel cells, electrical generators and other alternative energy sources, to the utility without the necessity of installing a sub panel or replacing an existing panel, resulting in significant cost savings for the user and increased electrical energy available to the power grid. The invention further discloses installation of a back feed circuit breaker into an existing main panel and main circuit breaker thus, eliminating the need of a home owner to completely reinstall a new electrical system in order to install alternative energy sources such as for example, solar panels and the like.

A line terminal is for an electrical switching apparatus. The electrical switching apparatus includes a stationary contact and a movable contact structured to move into and out of engagement with the stationary contact in order to close and open the electrical switching apparatus, respectively. The line terminal includes a lip portion structured to be connected to the stationary contact in order to provide an electrical pathway therebetween; an arm portion extending from the lip portion, the arm portion having an engaging portion structured to receive and engage a conductive post member and provide an electrical pathway between the conductive post member and the stationary contact; a neck portion extending from the arm portion; and a tab portion extending from the neck portion and being located internal with respect to the engaging portion.

The present disclosure provides a conductive member for a circuit breaker high voltage portion conductor assembly, the conductive member including a body with a transfer portion and a coupling portion. The body transfer portion has an electro-thermally efficient contour. That is, the body transfer portion has an electrically efficient contour and a thermally efficient contour. The body transfer portion includes a number of slots defining fins. In this configuration, the body transfer portion distributes current generally evenly across a cross-sectional area of the conductive member body. Further, the fins provide heat dissipation via convection.

A DC circuit breaker includes a gas discharge tube (GDT) coupled in parallel with an extinguishing path. The GDT conducts and interrupts a load current through a normal current path. The GDT includes a thermionic cathode, an anode, and a control grid. The control grid is configured to regulate opening and closing of the normal current path. The extinguishing path is configured to lengthen a break time for the DC circuit breaker.
