I have an outlet that I want to pickup another outlet off of ,but the feed
to the outlet is 12/aluminum ,then they have off the outlet 12/copper to the
next outlet.I want to add another12/copper to this box ,which is plenty big
enough changed that all ready.to add an out let . but that aluminum wire is
confussing me, would normaly just put the feed and 2 load wires together
with a wire nut and use a pigtail to feed outlet in box. but becouse it has
that aluninum feed wire how should I connect these ,could I just put an
antioxide grease on the alum. when I connect them? rite now the alum. is
just to one screw on the outlet and the copper on the other screw.
thanks for your advise.
There is such thing as AL/CU compatible components.
12Ga Al wire is equal to 14Ga Cu. My last house had all Al wire.
Never had trouble for 20 years but one reason I am out of there just
to have peace.
The problem is Al is softer than Cu and they expand at different rate
when getting hot.
house wiring was that even if the wires were originally put on
'dead tight' the different rate of expansion could, and did,
result in some loose wiring that caused a greater chance of
electrical fires. I'm thinking around 1970s?
