ABSTRACT:
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.
