A terminal block assembly for electrical generators, such as high speed AC generators used in aircraft, is made from components that are readily assembled and disassembled for ease of installation, maintenance, and repair. The terminal block assembly is formed of a terminal block and one or more terminal assemblies. The terminal block has a main body with at least an upper surface and a lower surface. A first cavity is formed in the main body lower surface, and an opening that extends through the main body between the upper surface and the first cavity. A threaded fastener is inserted into the opening and into the first cavity, and a bolt is coupled to the fastener to secure the fastener in the opening. Each terminal assembly is coupled to the terminal block and includes one or more electrically conductive terminal plates, feed-throughs, and slugs for connection to stator output leads, that are electrically and mechanically coupled together using electrically conductive fasteners.
