Service Wire Trimming

What’s the word on trimming service wire to make them fit the lugs on a panel. Had a 1/0 copper service wire today attached to a panel rated at 125 amps and a few of the copper strands in the cable had to be clipped to fit inside the panel lug.

Snipped strands of SEC?

I would write that one. Trimming off conductors is not allowed. I believe it is covered is 3 different NEC’s

It is damaged and needs to be repaired.
