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?


The required method is to have a receptacle behind the stove with a
range
cord plugged into it. If the existing box is big enough, such as a 4"
square x 21/8" deep or a 411/16" square x 21/8" deep, then you can mount
it
low and install a range receptacle with a square surface cover. The
other
choice is to remove the cable feed from the existing box and bring it
into a
surface mount range receptacle. Of course either method will require
the
installation of a range cord on the stove. Depending on your feed wire
the
receptacle and range cord can be 3 wire or 4 wire. The new range
receptacles are usually rated for copper and aluminum connections, but
with
aluminum wire the use of Penetrox is a good practice. There is no
reason to
remount the junction box underneath the kitchen. That would just be
more
splices that could cause a problem down the road.



Why does there have to be a plug & socket? It's not accessible, so it
doesn't serve as a means of disconnect. I would make sure the
connections are clean and tight, and leave it alone.

Aluminum cable and flexible conduit are not suitable for use as a portable
cord. When the range is pulled out for cleaning or servicing the aluminum
will bend each time as will the flex. Some ranges have access to the rear
by the removal of the bottom drawer or panel. That access satisfies the
requirement for a disconnect using a receptacle and cord.
