Blackburn 2HPW – Frequently Asked Questions
1) What wire range does the Blackburn 2HPW split bolt connector cover?
The Blackburn 2HPW is rated for 2 AWG solid down to 8 AWG solid conductors, which is where the "2SLD-8SLD" in the description comes from. The main run and the tap both have to fall inside that range for the connector to seat properly on the bolt.
2) Can I use the 2HPW split bolt on aluminum conductors as well as copper?
Yes. The 2HPW is an aluminum-rated split bolt connector (the "AL" in its description), built from copper alloy with an electro tin-plated finish. The tin plating is what makes it suitable for aluminum-to-aluminum and aluminum-to-copper connections, since it keeps the bare copper alloy from sitting directly against aluminum.
3) Is the Blackburn 2HPW UL listed for an inspected installation?
It carries UL file E9809. That is the listing number an inspector or a spec writer will look for on a mechanical connector, so the 2HPW can go into a UL-listed tap or splice without a separate submittal on the connector itself.
4) Can I use the 2HPW on stranded conductors, or is it solid wire only?
The rating on the 2HPW is stated in solid sizes, 2 AWG solid through 8 AWG solid. If the conductors on your job are stranded, match to a split bolt whose published range covers the stranded size you are running rather than assuming the solid range carries over, since the same AWG number is a different diameter stranded.
5) What does the "W/SP" mean on the 2HPW, and do I still need to tape the connection?
"W/SP" means the connector ships with its spacer, the insulating separator that sits between the two conductors on the bolt. The spacer is part of the connector, not a separate order line. It does not insulate the finished joint, though. A split bolt tap still needs to be taped or covered with an insulating cover to the voltage of the circuit.
6) Will a split bolt work for my tap, or do I need a compression connector?
A split bolt like the 2HPW is a mechanical connector, tightened with a wrench, so it is the practical choice when you have no crimp tool and dies on site or when the joint may need to come apart later. A compression (crimp) lug or C-tap is what you want for a permanent direct-burial or submersible connection, or where the spec calls for an irreversible compression connection. For a taped-up tap in a pull box or a gutter on 8 through 2 AWG solid, the split bolt is the normal answer.
7) Do I order the 2HPW split bolt individually or by the box?
It sells each, so you buy the exact count you need rather than a carton. For a panel change or a service tap where you are only making two or three connections, order the quantity of connections.
8) Where is the Blackburn 2HPW made? I have a domestic-content requirement on the job.
Country of origin on the 2HPW is Mexico. If your project carries a Buy American or domestic-content clause on electrical materials, this connector will not satisfy it and you will need a domestically produced mechanical connector instead.
