Blackburn 40HPS – Frequently Asked Questions

1) What wire sizes does the Blackburn 40HPS split-bolt connector accept?
The Blackburn 40HPS handles conductors from 4/0 AWG down to 4 AWG, so it covers most service-entrance and feeder taps as well as smaller branch conductors. Both sides of the bolt take conductors within that range, which is what lets you tap a smaller conductor off a larger run without changing connector sizes.
2) Can I use this split-bolt to connect copper to aluminum conductors?
The 40HPS is a copper alloy connector with an electro tin-plated finish. Tin plating is what protects the copper body against corrosion and keeps contact resistance stable over time. Copper alloy split-bolts are intended for copper conductors; for aluminum or mixed copper-to-aluminum taps you need a connector specifically marked AL9CU or dual-rated.
3) Is the Blackburn 40HPS split-bolt UL listed for inspected commercial work?
It carries UL file E9809 as a mechanical connector, which is the listing an inspector looks for on a split-bolt used in commercial or industrial installations. That covers use in service panels, utility distribution and general feeder tap work.
4) Do I need special tooling or a crimper to install a split-bolt connector like the 40HPS?
No crimper or die set required. A split-bolt is a mechanical connector: you seat the conductors in the bolt body and torque the nut down with a wrench. That is the reason crews reach for them on service and repair work where dragging a hydraulic crimper into a panel isn't practical. Plan on insulating the finished connection separately, since the split-bolt itself is bare metal.
5) Does the 40HPS come with insulation or a cover?
It ships as a bare connector only, sold individually rather than in a kit or pack. The bolt, nut and spacer are the connector; tape, a rubber pad and insulating cover, or a shrink boot are ordered separately and sized to the finished connection.
6) Is a split-bolt the right choice for an underground or wet-location splice?
A split-bolt is a dry-location tap and splice connector. The tin plating on the 40HPS resists corrosion, but the connection itself is not sealed, so direct burial or submerged splices call for a listed underground device such as a mold-filled or gel-filled splice kit, or a compression connector with heat-shrink. Use the split-bolt in panels, pull boxes, gutters and similar protected locations.
7) How do I order the exact Blackburn split-bolt for 4/0 conductors rather than a look-alike?
Specify Blackburn part 40HPS. The size suffix on split-bolts drives the conductor range, so a catalog number that differs by one or two characters can be a completely different AWG window. The 40HPS is the copper alloy, tin-plated version covering 4/0 through 4 AWG, made in Mexico.
8) Can I use one 40HPS split-bolt to land two conductors of different sizes, like 4/0 to 2 AWG?
Yes, as long as both conductors fall inside the 4/0 to 4 AWG range. That is the normal use for this size: a large feeder run with a smaller tap conductor pulled off it. Torque the nut so both conductors are fully seated against the bolt body and the spacer stays between them.
