Aluminum- Copper pigtail
The splice in this panel has me a little concerned. By the size and shape of the tape wads I would have to guess they are wire nuts and not copalum crimp splices. The house was built in 2000 and I think the purple wire nuts were code compliant at the time (and may still be), but can't tell if they are the Ideal #65 type or not.
There have been several threads regarding the different splices and the purple Ideal #65 is known to have failed.
What, if anything would you put in the report?
Thanks in advance.

It looks like they used a split bolt to change from alum to copper so the wire would fit on a 30 amp breaker. The only concern, if any, would be if they used a copper to alum split bolt. If I saw that and the rest of the panel looked OK I would not say anything.
Lot's of time the electrician does not know what is going to be installed so they run a wire to handle most anything. I bet this circuit is for an outside condensing unit or heat pump.

Re: Aluminum- Copper pigtail
Just for argument sake...
Assumming both wires are copper, is there an approved wire nut that would handle the two different wire sizes?
And you have 2 breakers feeding a single wire with the lower splice. Turn off one breaker and the wires are still engerized.
Get a sparky in there.

Re: Aluminum- Copper pigtail
Why the splice? A 30 amp QO breaker will accept 8 awg al/cu.

Maybe it is a #6?
