GFCI breakers will still protect you if you stick a fork in a toaster
even with aluminum wire.

You should never connect a copper only rated device to aluminum wire because
it creates a serious fire hazzard. If you don't know that you shouldn't be
answering questions from people who obviously already know more than you.

I got a jar full of pennies and nickels and dimes?.

How come it hasn't caught on fire yet?

GFCIs protect against L-E shocks and shorts, which have nothing to do
with the risk that ali wiring posts. Al oxidises at joints, heats up &
catches fire. A gfci doesnt make the remotest difference to that. An
AFCI however would.

I'm not that familiar with US practices, but I dont expect many modern
electrical parts will have al compatible connections.

yup. If you need to put an AFCI in each circuit, the AFCI can have a
copper tail leading to a purpose designed cu to al connector. Follow
the proper procedure in the instructions, al behaves differently to
cu.

AFCIs arent perfect, but they do reduce risk quite a lot.

How much current passes through your pennies and dimes? Are they
protected by an AFCI?

All wiring devices like receptacles, switches, GFCI breakers etc. are marked
for Alum. and or copper usage.
Some are copper only some are will work with both.

If in doubt you could make a short jumper. If your circuit conductor is #
12 or #10 alum. use a copper
#12 conductor spliced to the circuit conductor using a copper/alum. butt
splice A compound such as peremetx
could also be used to coat the conductors. Permitex is a paste like
compound that contains both copper and
aluminum metals.

I'm under the impression that current AFCIs don't protect against the
type of arc faults Al joints are prone to.

I'm not installing GFCIs to mitigate the Al risk, it's to mitigate the
general risk of operating electrical devices near water.

I'm not that familiar with US practices, but I dont expect many modern
electrical parts will have al compatible connections.

Switches and outlets do, actually, but GFCI outlets seem to be an
exception.

AFCIs arent perfect, but they do reduce risk quite a lot.

Do you have any references that show currently marketed AFCIs to
reduce the risk of bad Al connections?

I read that the butt splice method is not a good idea and that is why
the COPALUM pigtail splice exists. Same deal with the Ideal purple
wire nuts vs Scotchlok wire nuts that are spring loaded. In both
cases the latter exerts more force on the aluminum wire keeping it
from loosening as it inevitably expands and contracts.

no, I didnt realise they were parallel only. Where I am in the world
we dont have AFCIs.

You are correct...CP/AL spring loaded nuts could be used.
I used Scotchlock spring loaded nuts for years and never had a problem

There is a new device out there called Alumiconn by King Innovation
that is as good as Copalum and you don't need any special tools or
training.
It is a small terminal block with set screws in an insulating jacket.

Yeah, that looks like a good product and it's even UL listed. But
it's not listed by CPSC as an approved repair method (yet). This
might be the best way to go in the end, the product makes sense and is
not that expensive.

Do you have a suggestion where I could find such a nut? All the
Scotchlok nuts I have found on their site say Copper connections
only... though it certainly seems that CO/ALR spring nuts do exist
somewhere.
