Trumpy:
They looked like they were rated at 400 amp fuses? I will look again at the video to be sure this week. Your scenario about the "wire termination compound" is a good one.
I think that the gloves used are usually put into a bag for protection and should not be used for actual installations, but knowing that workers will use them sometimes can lead to what you are concerned with.
Now we should look for any restrictions or guidelines toward that additional safety rule, if any.
