Exterior splicing is this acceptable ?

Hi, who can assist me on if this exterior terminal end connectors, is this acceptable for the service lines or does it just need wrapped with electrical tape. To me it just doesn’t look right, your help will be greatly appreciated as Ive never seen this to be visually seen before.

I don’t have a problem with it. That connection is usually from the power company.

I doubt the power company used wire nuts. It also looks too small to be a service.

I don’t see the issue.

Where does the service entrance cable go after the masthead? into the attic? thats a no no unless the panel is up there too.

The blue wire nuts are unacceptable. Is this a service or power to an outbuilding? There could be several issues do you have more photos?
