A method, installation tool, termination fittings, and test apparatus, for mass-production retrofit of aluminum wiring systems installed in buildings from 1965 to 1973, when aluminum was approved by many inspection departments. The re-termination fittings are customized for mass production on the basis of the sizes (10, 12, etc.) of the existing wire, the required movement of which with this method is minimal, an important factor in view of its frangibility. The battery-operated portable tool solidly swages the fittings to one, two, or more wires. Connection is made to duplex receptacles, the most frequently encountered device, by copper stubs which engage with both screws of the same polarity, assuring that the re-termination fittings are thus firmly fixed to the receptacle, and minimum wire movement will be required. With the re-termination fittings and the method of conductor arrangement, the electrician\s work is easier and faster.

An electrical connector for re-terminating at least one previously installed solid aluminum conductor, of the type now outlawed, at a pair of conductor-securing screws, of the same polarity, of a duplex-receptacle, the connector comprising: a block of electrically high-conductive material, in the general shape of a rectangular parallelopiped, having a front, a back, a top, bottom, and two sides; stub-like electrical conductors, integral with said block, on centers equivalent to those of said receptacle screws, projecting perpendicularly from said front, said stubs of a length suitable for securing said block to said receptacle, when each of said stubs is engaged with one of said screws; said parallelopiped having at least one cylindrical bore, from top to bottom of the block, said bore slightly larger than the diameter of said previously-installed conductor, now to be installed therein; and said block being positioned within retaining means and indentable from said front and said back, in chisel-tip fashion along a predetermined length of said conductor, said chisel tips in centered alignment with said conductor, into intimate contact with the entire surface of said conductor, and further indenting cylindrical surface of said conductor into a figure-eight like cross-sectional area, said indentations acting as a couple to prevent rotation of said aluminum conductor within said bore of said connector block.
