No/yes/maybe/some places
Aluminum wire has been used in housing construction since the 1960s, but it is no longer popular owing to concerns about cost savings outweighing disadvantages. In some locations, though, it is still permitted.
From the mid-1960s through the mid-1970s, aluminum wiring was widely utilized in Canada.
Nonetheless, Aluminum wire is very popular in the utility and industrial markets since it can handle much power. Overhead utility wires are almost all made of aluminum or aluminum conductor steel-reinforced (ACSR) cables.
How To Detect Aluminum Wiring
Aluminum wiring is easy to identify. The outer covering of the cable ( Every 10 to 12 inches ) will be marked with the word "aluminum" or an abbreviation such as "ALUM" or "AL."
Special service connections are required when the aluminum wire is used.
“CU-AL” is the marking that should be used on switch and outlet boxes. This informs users that the equipment is compatible with aluminum wiring. Circuit breakers would also have this mark. Electrical outlets, wall switches, and fuse boxes intended to be used with copper wire are unsuitable for aluminum wiring use.
