If in doubt you could make a short jumper. If your circuit conductor is #

could also be used to coat the conductors. Permitex is a paste like
compound that contains both copper and
aluminum metals.

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.
