Blackburn 500HPS – Frequently Asked Questions

1) What wire sizes does the Blackburn 500HPS split-bolt connector take?
The Blackburn 500HPS is rated for 500 kcmil down to 1/0 stranded conductor. The main run can be up to 500 kcmil and the tap can be as small as 1/0 STR. Going below 1/0 on either side means moving to a smaller split-bolt in the range, not shimming this one.
2) Can I use a tin-plated split-bolt like the 500HPS on aluminum conductors?
The 500HPS is a copper alloy body with an electro tin-plated finish, and the range is called out as 500-1/0 STR copper. Tin plating is there for oxidation resistance and connection reliability on copper work. For aluminum or combination copper-to-aluminum splices, use a connector specifically listed AL9CU for that service rather than assuming this one covers it.
3) Is the 500HPS split-bolt UL listed for electrical work?
Yes. It carries UL E9809, which is the listing referenced for this Blackburn high strength split-bolt. That is the standards reference an inspector or spec writer will want on a service entrance or panel splice.
4) What is the exact part number to order for the Blackburn 500-1/0 high strength split-bolt?
Order Blackburn 500HPS. That is the manufacturer part number for the high strength split-bolt covering 500 kcmil to 1/0 stranded, copper alloy with tin plating. The HPS suffix indicates the high strength version, so do not substitute a standard-strength split-bolt of the same wire range if the spec calls for high strength.
5) Do split-bolt connectors need to be taped or insulated after installation?
Yes. A split-bolt is a bare mechanical connector, so the completed splice has to be re-insulated to the level of the conductor insulation, normally with rubber splicing tape built up over the bolt and then overwrapped with vinyl electrical tape, or with a listed insulating cover. Nothing insulating ships with the 500HPS itself.
6) Should I use a split-bolt or a compression connector for a 500 kcmil splice?
A split-bolt like the 500HPS is a mechanical connector, tightened with a wrench, so no hydraulic crimper or dies are needed and the splice can be taken apart later for testing or re-tapping. Compression sleeves are the choice where you want a permanent, lower-profile splice or where a submersible or direct-burial rated connection is called for. For panel, service entrance, and industrial branch tap work where access is fine and tooling is limited to hand tools, the split-bolt is the practical pick.
7) How is the 500HPS sold, individually or in a box?
It is sold each, so quantity is per connector. On a three-phase plus neutral splice you are ordering four, and most electricians add a spare to the count.
8) Where is the Blackburn 500HPS connector manufactured?
Manufacturing origin is Mexico. That matters on public work with domestic-sourcing clauses, so check the job's procurement language before specifying it on a federally funded project.
9) Will a tin-plated split-bolt hold up in a damp or corrosive electrical room?
The copper alloy body with an electro tin-plated surface is there to resist oxidation, which helps in humid switchgear rooms and industrial environments. It is still a bare mechanical splice, so it needs proper insulating build-up and, in genuinely wet locations, a connector listed for wet or direct burial use is the better call.
