In the course of kitchen remodeling, when I pulled the range away from
the wall, there was an electrical box lying on the floor (unfastened),
with the wire from the service coming up through the floor going in,
and enclosed in a flexible conduit, the wires carrying power to the
stove. Yep, Cu-Al connectors in the box.
Well rather than the current setup, I'd like to use something more
standard; a wall socket for the range.
How about just mounting that box with the CuAl connectors to a joist
underneath the kitchen, then coming up to a socket with copper?
