You CAN use pigtails - with either the expensive crimp-on system or
the bi-metal wire nuts - but the wire nut pigtails in particular are
actually more problematic than a non-CoAlr device directly on the
aluminum wire.(assuming second generation aluminum)


Probably not much 2nd generation wire around. But the UL testing for
CoAlr devices is done with it.

There was extensive research done on aluminum connections for the CPSC.
The engineer that did the research did not like the only wire nuts that
are UL listed for aluminum (Ideal 65?). He preferred 3M ScotchLoks,
after abrading the wire to remove oxide and adding antioxide paste. Wire
nuts installed that way are quite reliable, and certainly better than
some of the non-CoAlr devices.

He now recommends King Innovation AlumiConn connectors.


The alumiconns are the ones that require a trained, licences, and
certified installer and cost about $10 each installed???
