Joining #3 gauge aluminum to copper wires

935 Views 3 Replies 3 Participants Last post by  seharper
My new range/oven requires a 240V-50 amp "Y" plug outlet to be mounted on the stud-wall base. The existing plug is mounted about 6 inches too high My solution is to mount a new outlet on the stud-wall base and join a 3 gauge extension from the original junction box to the new outlet The solution works, although this creates a problem

After I opened the wall, it appears that the original service is 3 gauge aluminum. To have a working range/oven, I joined the two wires using wire nuts. I cannot find an aluminconn wire nut or some other solution intended for joining dissimilar metal wires of this gauge.

Is there an easier solution besides replacing the original service?

Code dictates that an existing 3 wire stove feed can not be extended.
3 gauge is a pretty good size wire. Are you sure it is not #6?

Polaris connectors can be used to connect dissimilar wire types.
