6 GAUGE ALUMIMUN to 12 copper

Have old 240 circuit 60 amp breaker and I think 6 aluminum that I want to put a 20 breaker and outlet in. Need to know what to use to go from 6 to 12 gauge copper wire. Also they used a standard 2 gang box and I will be only using one side of it. Is there a mud ring or something I can convert box to a single 240 outlet.

Since it is aluminum wire you will need to use a splice rated for aluminum to copper. Something like a split bolt or a Polaris insulated connector: https://www.homedepot.com/p/Polaris-...-303579042-_-N

With that splice, you will need the space of a 2 gang box. Is the existing box a plastic or metal box? Is it for two devices or does it have a mud ring now?

Another option would be to use the existing wire as a feed and install a small subpanel, or install a larger box up high and install a single gang box lower for your new device.

Splice blocks are pretty low profile too.
