Electrical busway assemblies and methods and devices for applying compressive forces to a busbar stack in an electrical busway assembly are disclosed herein. Electrical busway assemblies for distributing electricity are presented. The busway assembly includes a stack of electrically conductive busbars with one or more duct sides each disposed on a respective side of the busbar stack. Optionally, a duct top and duct bottom can be placed on the stack top and stack bottom, respectively. A surge clamp engages the stack top or stack bottom. A bolt attaches the surge clamp to each duct side. A compression nut threadably engages each bolt. Rotation of a bolt moves the corresponding compression nut, which acts to move the surge clamp along a path that is oblique with the path of the compression nut. The surge clamp, when moved by the compression nut(s), acts to apply a compressive force to the busbar stack.
