“While the old pejorative attitude is still somewhat of a problem, aluminum conductors have experienced a significant increase in use for building wire over the last 10 years,” she said. “Contractors, engineers and owners have gained confidence based on the fact that AA-8000 series aluminum alloy conductors have been installed and operating reliably for over 40 years.”


To start, the stuff is made with the AA-8000 aluminum alloy. This alloy became the required standard for aluminum wiring to resolve the problems of the poor quality aluminum wiring used prior to 1972 (AA-1350 aluminum). Adding the copper cladding allowed the wire to be connected to devices that did not have to be rated for “aluminum.” In fact, brand new, 2014, receptacles that are Tamper Resistant, come rated for both copper and copper-clad wires. This is a testament to the fact that receptacle manufacturers do not see a problem with copper-clad wiring.
