Ranges and dryers of yesteryear had only 3 wires, 2 hot and neutral/ground.
They had to be on a dedicated circuit so as to not energize some other

Now days these appliances all require 4 wires. Old ones are still
grandfathered as far as I know.
But the discussion was about the main feed to the breaker panel.
