I’m changing the load panel in a mobile home with additions to gain additional circuits.
Outside a few feet from home is the service pole with meter and a 100 amp disconnect.
I became concerned about the entrance wire because it is a fine stranded wire like automotive battery cables or like welding equipment wiring. The picture shows the work in progress and it is complete now but I wonder if this type wire is anything to be concerned about especially since I will be adding to the load draw with a central heat pump.
In the red square you can sort of see the fine strands that the entrance wire has. I can’t get better pictures until I return to this vacation home.

it's not common for sure, and if it was fine stranded, then it's a 110.3 labeling/listing vio as loadcenter lugs aren't listed to accept it, but it's definitely possible

I see Mr. Snippy has been in the panel and cut back all but the minimum possible wire length. Better to leave enough length to allow hot+neutral to reach any space in the panel. Neutral too because GFCI+AFCI.

I can call it right now.
I don't see any markings on the wires. Now, perhaps the wires come out of a multiconductor cable, whose cable sheath has markings that indicate it is one of the NEC/UL rated types of wire legal for mains wiring. But if not...
Wires without insulation markings are no wires at all.
You don't even know what you're looking at here. You don't know what insulation temp column you should be pulling out of for 310.15(B)(16). You don't know if it's 600V insulation. We don't know if the insulation will hold up over time, in the environmental conditions, or with the heat of the wires working normally. For all we know it could be Chinese car battery cable.
Given that it's all 4 colors, there's a fair chance it's cable in sheath, or was shucked from cable in sheath (there go the markings). This is why you can't shuck NM to get wires for running in conduit.

We do know it has held up over time since the original setup of mobile home was in 1969. What I don’t know is if it will hold up in the future with a heat pump being added to the mix. There was no ac in this house only a small electric furnace which was rarely used since it is a summer destination. I’m thinking I will replace the short run from outside disconnect to panel.
