I am not promoting sloppy ugly work I am just pointing out that electricity does not have eyes and a sloppy looking connection can perform fine.
Here is a motor switch in a roof top make up air fan. The liquid-tight conduit supplying it had literally rotted away leaving the THWN exposed to the weather. I think we can assume if it has been in service so long that the LFMC had rotted away that this has been like this for some time. I was there to replace the LFMC and I also swapped out the 10 AWGs with 12 AWGs so I could terminate them a bit neater.
I included a close up as I know someone will ask about the insulation damage on the black conductor. I don't know what caused that damage but it does not appear to be connection related to me.
