Duplex cable has been around since before 1918. The great debate continued for over a decade, but in 1903 the code was revised to recommend that these circuits be grounded, and finally in the 1913 code a mandatory circuit.

The great debate continued for over a decade, but in 1903 the code was revised to recommend that these circuits be grounded, and finally in the 1913 code a mandatory circuit. The c wire, or “common wire” enables the continuous flow of 24 vac power to the thermostat. Modern nm (nonmetallic) cable, which includes a bare grounding wire, was introduced in 1965.
Technically Speaking, Power Flows From The R (Red) Wire, But Not Continuously (Not.
Homes built before 1965 were unlikely to have aluminum conductor.
