Blackburn 4HPW – Frequently Asked Questions
1) What wire sizes does the Blackburn 4HPW split bolt connector take?
The Blackburn 4HPW handles 4 AWG solid down to 12 AWG solid, per its 4SLD-12SLD range. That covers a main run of 4 solid tapped down to a 12 solid branch or ground conductor, and anything in between within that span. Outside that range you need a different size in the split bolt family.
2) Can I use the Blackburn 4HPW to tap aluminum conductors, or is it copper only?
It is rated for aluminum as well as copper conductors, which is what the AL designation in the description signals. The body itself is copper alloy with an electro tin-plated finish, and that tin plating is what lets it sit against aluminum without the galvanic corrosion you get from bare copper on aluminum. It works for AL-AL, AL-CU, and CU-CU combinations inside its 4 solid to 12 solid range.
3) Is the 4HPW split bolt UL listed for an inspected job?
Yes. The 4HPW carries UL file E9809 as a mechanical connector, so it is a listed device for an inspected installation. Use it within the conductor range and combination it is listed for, and insulate the completed tap per your local code, since a split bolt is a bare mechanical connector and not self-insulating.
4) What does the W/SP mean on the Blackburn 4HPW?
W/SP means it comes with the spacer, the separator plate that sits between the two conductors inside the bolt. That matters when you are joining two very different wire sizes or aluminum to copper: the spacer keeps the small conductor from being crushed and keeps dissimilar metals from bearing directly on each other. It is included with the 4HPW, so you don't order it separately.
5) Should I use a split bolt like the 4HPW or a compression tap for a service tap?
A split bolt such as the 4HPW is a mechanical connector, tightened with a wrench and reusable, which makes it the practical choice for field taps, ground bonds, and anywhere you may need to break the connection later without special tooling. Compression connectors need a die and crimper and are the pick where you want a permanent, dressed-down joint or a factory-style submersible connection. For a 4 solid main tapped to a 12 solid conductor, the 4HPW does it with hand tools.
6) Can I use the 4HPW on stranded wire or only solid?
The stated range on the 4HPW is 4 solid to 12 solid. Size the connector to the conductor range printed on it, and where you are terminating stranded conductors choose the Blackburn split bolt whose range covers that stranded size rather than assuming the solid-only rating carries over.
7) Do I get one split bolt or a box when I order the Blackburn 4HPW?
The 4HPW sells each, one connector per unit, so an order quantity of 10 gets you 10 connectors. Count one per tap when you are estimating a job.
