Was being nosy yesterday. Went into a roughed in house going up in a new sub division. The branch circuits were run in 12 an 10 Copper clad aluminum nm cable.

when did this become available?

are devices now being sold that are Al rated?
 
With copper clad AL you can use standard devices. I would still prefer copper be used for branch circuits.

The following is from the UL Guide Information is from "Receptacles for Plugs and Attachment Plugs (RTRT)"
Terminals of 15 and 20 A receptacles not marked "CO/ALR" are for use with copper and copper-clad aluminum conductors only. Terminals marked "CO/ALR" are for use with aluminum, copper and copper-clad aluminum conductors.

The Guide Information for Snap Switches (WJQR) uses the exact same working.

The issue becomes the wire connectors. The Guide Information for Wire Connectors and Soldering Lugs (ZMVV) says that you need a wire connector marked CU/AL for connecting copper-clad conductors to other copper-clad conductors or to copper or aluminum conductors.

Question how did you tell it was CU Clad AL? is the jacket yellow for 12 and orange for 10?

No, yellow for the 10, white for the 12. Had to read the jacket. The contractor usually uses romex colored purple for 14 and orangish for 12, has the company name on the jacket as well. As you can imagine they rope in loads of houses.
hope the ropers can keep up on the box fill. Also goodbye backstab.

Thanks, I know the devices I buy, including gfci's are limited to 12. So now it would seem Tailing the 20a circuits may be necessary.

Only possible with 14 gauge now, but higher quality devices with pressure plate connectors are the best choice.
