One of the AL wires looks to have heat damage on the insulation

How you notice these things, from where you sit, and I don't even
*see* it when I'm directly in front of it, I'll never understand.


Hey. I even know what size shoes you have, remember g.

You're right! It's dark outside now (and I buttoned it all up),
but, here is a large-format picture that I had taken earlier.

What would make that huge neutral get that hot so as to melt
the insulation to a caramel color?


A poor connection? Age of the install? Look at the AL wire under the
heat damaged / rusted screw / corrosion. The insulation end is black
from heat melting it more.

Get this looked at and fixed. AL wire can cause fires when stuff gets
bad. Not to frighten you, but AL wires have caused plenty of fires in
homes..

Notice the Al wire under the heat damaged one also is colored with a
yellow tint.

Could it be as simple as that rusty screw?

And a poor contact at the screw. Seem to recall they use some type of
gel to reduce arching, etc.

As I stated, I'm not giving electrical advice but speaking from things
I've read. I'd have a pro look at it and fix it.
