Blackburn 20HPS – Frequently Asked Questions

1) What wire sizes does the Blackburn 20HPS split-bolt connector take?
The Blackburn 20HPS split-bolt handles copper conductors from 2/0 AWG down to 6 AWG. That range covers most service entrance taps and feeder splices, and it lets you join two different gauges within that window, say a 2/0 run to a 1/0 tap. Anything larger than 2/0 or smaller than 6 AWG needs a different size of split-bolt.
2) Can I use this split-bolt on aluminum conductors?
No. The 20HPS is specified for copper conductors only, 2/0 through 6 AWG. For aluminum or for a copper-to-aluminum transition you need a connector rated AL/CU and filled with the appropriate inhibitor compound. Using a copper-only split-bolt on aluminum risks galvanic corrosion and a loose joint over time.
3) Is a split-bolt connector UL listed for use in a panel or service entrance?
The Blackburn 20HPS carries UL file E9809. It is a mechanical connector, so it is made up with a wrench rather than a crimp tool, which is why electricians use them for panel connections, service entrance taps, and grounding electrode conductor splices where a hydraulic crimper is not on the truck.
4) Do I need a crimping tool to install the Blackburn split-bolt?
No special tooling. The split-bolt is a threaded mechanical connector, so the conductors are laid into the body and the nut is torqued down with a standard wrench or socket. That is the main reason it stays in the toolbag for field splices and repairs where a hydraulic or battery crimper is not available.
5) Does a split-bolt splice need to be taped or insulated after it is made up?
Yes. A split-bolt is a bare mechanical connector, so the completed joint has to be re-insulated to the level of the conductor insulation, normally rubber splicing tape built up over the connector followed by vinyl electrical tape, or a split-bolt insulating cover. The electro tin-plated copper alloy body gives corrosion resistance at the contact surfaces, but it provides no insulation on its own.
6) What part number do I order for a 2/0 to 6 AWG copper split-bolt from Blackburn?
The manufacturer part number is 20HPS. Blackburn sizes split-bolts by conductor range, so the 20HPS is the one that covers 2/0 through 6 AWG copper. It is made in Mexico.
7) Why is the connector tin-plated instead of bare copper?
The electro tin plating on the 20HPS slows corrosion at the contact faces and keeps the threads turning freely, which matters in damp service entrance enclosures, pull boxes, and outdoor gear. Underneath, the body is copper alloy for conductivity and thread strength.
8) Is the Blackburn 20HPS sold individually or in a box?
It is sold each, so you order the exact count the job calls for rather than a fixed carton. Handy when a panel change only needs three or four splices.
