Blackburn 1000HPS HSTRNGTH SPLITBOLT CONN 1000-500

The 1000HPS is sized for a 1000 kcmil run conductor down to a 500 kcmil tap, which is what the 1000-500 in the part designation refers to. It is a high strength split bolt, so both conductors are clamped between the bolt body and the pressure bar as the nut is drawn up. For anything smaller than 500 kcmil you want a different catalog number in the split bolt range rather than shimming this one.

Yes. It carries UL file E9809 as a mechanical connector, which is the listing an electrical inspector looks for on a tap or splice connector in a panel, pull box, or gutter.

The 1000HPS body is copper alloy with an electro tin plated finish. Tin plating is what allows a copper alloy connector to be used against aluminum without the bare copper to aluminum contact, so the plating is the detail to check against your conductor material and the connector's own listing markings before you make the tap.

Yes. A split bolt is a bare mechanical connector, not an insulated device, so the completed tap has to be built back up with rubber splicing tape and vinyl tape, or covered with an insulating cover, to the insulation level of the conductors. Nothing insulating ships with the connector itself.

High strength versions such as the 1000HPS are built for the torque required on large conductors, which is why they show up on 500 kcmil and larger taps where a standard duty split bolt would not take the wrenching. For smaller branch and feeder conductors a standard split bolt, or a compression tap if you want a permanent crimped connection, is the usual choice.

They are sold each, so order one per tap or splice you are making. On a three phase 1000 kcmil feeder tap that means three, plus one for the neutral if you are tapping it.

Country of origin is Mexico. That matters on federally funded work with Buy American or domestic sourcing clauses, so check the origin requirement in your spec before submitting it on a public project.
