A helical jumper connector includes a helical support member configured to support a wire. The helical support member includes a first leg having a first helical winding and a second leg having a second helical winding that defines a second axial opening. The first axial opening and the second axial opening are coaxial with the wire when the first helical winding and the second helical winding are wrapped around the wire and cooperatively engage with one another to support the wire. A jumper casting is configured to receive the helical support member. The helical support member and the jumper casting are electrically conductive such that the helical jumper connector forms an electrically conductive pathway to carry electrical current from the wire. A method of making a helical jumper connector assembly includes applying a compression force to a helical jumper connector comprising a helical support member received in a jumper casting.
