We design our copper and aluminum units to meet the same specifications. Aluminum coils need to use larger wires, but the user does not see any difference. The copper coils are physically smaller, but we put them in the same enclosure as the Aluminum, so the user will not see any difference. The terminals are the same, so the user will not see any difference. Most wiring lugs are tin-plated so there is no problem connecting the transformer to aluminum or copper wires.
