Questions tagged [aluminum-wiring]

Aluminum wires were used for branch circuits in some older houses between the 60s and the late 70s. They are no longer used for residential branch-circuit wiring due to fire risk (old AA-1350) and economic (AA-8000) considerations, but existing wires can be maintained in a way that makes them relatively safe. AA-8000 wire and cable will be marked as such -- cable not marked as such can be assumed to be AA-1350.
