Here in NY The power companies won't allow split bolts anymore. I have repaired many, in years past. As soon as a customer says half my house is out that's where I look.
We now have to use either Hypress type connectors, most supply houses will rent you a mechanical crimper.
Or paralell groove connectors. Con Edison is only allowing a specific type of connector made by Richards, they come pre noaloxed and come with a plastic snap on cover.
