Blackburn 750HPS – Frequently Asked Questions
1) What wire sizes does the Blackburn 750HPS split bolt connector take?
The 750HPS is rated for a 750 kcmil main down to 4/0 stranded run, which is what the 750-4/0STR in the part description means. It's a high strength split bolt, so both conductors sit in the same bolt body and are clamped by tightening the nut. Outside that range you want a different size split bolt, since over-sizing the connector leaves the smaller conductor loose in the groove.
2) Can I use this split bolt on aluminum conductors, or copper only?
The 750HPS body is copper alloy with an electro tin-plated finish. Tin plating is what makes a copper-alloy connector suitable for use with aluminum as well as copper, since it keeps bare copper off the aluminum surface. Use a listed oxide-inhibiting compound on aluminum terminations as you normally would.
3) Do I need to tape or insulate the 750HPS after I make the splice?
Yes. A split bolt is a bare mechanical connector, not an insulated device, so the completed tap has to be insulated to the level of the conductor insulation, normally with rubber splicing tape plus vinyl over it, or a split bolt insulating cover sized to the connector.
4) What is the difference between a high strength split bolt like this and a compression tap?
The 750HPS is a mechanical connector: you tighten a nut with a wrench, no dies and no hydraulic tool, and the joint can be taken apart later. A compression tap is crimped permanently with a tool and specific dies. On large conductors like 750 kcmil, a split bolt is the usual choice when you don't want to bring a hydraulic crimper to the location or when the splice may need to be opened again; compression is preferred where a sealed, non-reusable connection is specified.
5) Is the 750HPS sold individually or in a box?
It's sold each, so you can buy exactly the count the job needs rather than a carton. Part number is 750HPS.
6) Where is the Blackburn 750HPS made?
Country of origin is Mexico. Useful if you're filing origin documentation on a government or institutional contract.
